Preface

This manual uses certain conventions that you should become familiar with.

ManualConventions

Some sections of the manual contain procedures for you to perform. To

keep those instructions clear and consistent, this manual uses the following

conventions:

Instructions for menu selection follow this format: FRONT PANEL BUTĆ

TON! Main Menu Button! Side Menu Button. For example, Press

UTILITY! Misc! Config...! Reset to Factory! O.K."

Names of front panel controls and menus appear in the same case

(initial capitals, all uppercase, etc.) in the manual as is used on the

AWG2005 front panel and menus. Front panel names are all upperĆcase

letters; for example, MODE MENU, CH 1, etc.

Instruction steps are numbered unless there is only one step.

Modules

Throughout this manual, any replaceable component, assembly, or part of

the AWG2005 is referred to generically as a module. In general, a module is

an assembly (like a circuit board), rather than a component (like a resistor or

an integrated circuit). Sometimes a single component is a module; for

example, the chassis of the AWG2005 is a module.

Safety

Symbols and terms related to safety appear in the Safety Summary near the

beginning of this manual.

Preparation for Use

This subsection describes how to prepare the AWG2005 Arbitrary Waveform

Generator for use. The information describes these items:

Proper operating environment

Checking power cord and line voltage configurations

Checking the fuse

PowerĆon and powerĆoff cycles

To ensure proper AWG2005 operation and long life, note these environmenĆ

tal requirements.

Operating

Environment

Operating Temperature

The AWG2005 operates in an environment with an ambient air temperature

between +10_ĂC and +40_ĂC. The AWG2005 storage temperature ranges

from -20_ĂC to +60_ĂC. After storage at temperatures outside the operating

limits, allow the AWG2005 chassis to stabilize at a safe operating temperaĆ

ture before applying power.

Ventilation Requirements

Air drawn in and exhausted through the cabinet side and bottom panels

cools AWG2005 internal circuits. To ensure proper cooling, allow the followĆ

ing clearances:

Top and back

Left and right

7.6Ăcm (3 in.)

15Ăcm (6 in.)

The feet on the bottom of the AWG2005 cabinet provide the required clearĆ

ance when it is set on a flat surface. The top of the AWG2005 does not

require ventilation clearance.

CAUTION

To prevent temporary shutdown of the AWG2005, do not restrict air

flow through the chassis. If the AWG2005 shuts down unexpectedly,

improve ventilation around the AWG2005 and wait a few minutes to

allow it to cool down; then switch the power on again.

Preparation for Use

Before installing the AWG2005, note these precautions:

Supplying Power

WARNING

To avoid equipment failure and potential fire or personal shock

hazards, do not exceed the maximum rated operating voltage of

250ĂV between the voltageĆtoĆground (earth) and either pole of the

power source. The AWG2005 operates from a singleĆphase power

source and has a threeĆwire power cord with a twoĆpole, threeĆterĆ

minal grounding plug. Also, before making connection to the power

source, be sure the AWG2005 has a suitable twoĆpole, threeĆtermiĆ

nal groundingĆtype plug.

To avoid personal shock hazard, do not contact conductive parts.

All accessible conductive parts are directly connected through the

grounding conductor of the power cord to the grounded (earthing)

contact of the power plug. The AWG2005 is safety Class 1 equipĆ

ment (IEC designation).

To avoid personal shock hazard, do not defeat the grounding

connection. Insert the power input plug only in a mating receptacle

with a grounding contact where earth ground has been verified by a

qualified service person. Also, for electricalĆshock protection, make

the grounding connection before making connection to the

AWG2005 input or output terminals.

The AWG2005 ships with the required power cord as ordered by the cusĆ

tomer. Table 2Ć1 gives the colorĆcoding of the conductors in the power cord.

Figure 2Ć1 shows information on the available power cords.

code. To exit the diagnostics menu, press any key; then the system displays

the SETUP menu. See section 6, Maintenance, for information on diagnosĆ

tics and fault isolation.

NOTE

If the ambient temperature goes outside the specified operating

temperature range, an error occurs during the diagnostics at powĆ

erĆon. If this happens, power off the AWG2005 and wait until the

chassis temperature is appropriate; then switch the power on

again.

PowerĆoff Cycle

CAUTION

To prevent loss of internally stored adjustment constants, DO NOT

power off the AWG2005 when doing the internal calibration deĆ

scribed in section 5, Adjustment Procedures.

Wait for the AWG2005 to finish the operation when doing internal calibration

or saving waveform or sequence files. Improper powerĆoff or unexpected

loss of power to the AWG2005 can result in the corruption of data stored in

nonvolatile memory.

Instructions for Operation

Before servicing the AWG2005, read the following operating instructions.

These instructions are at the level appropriate for servicing the AWG2005.

The user manual contains complete operator instructions.

In addition, section 4, Performance Verification, includes instructions for

making the frontĆpanel settings required to check AWG2005 characteristics.

To powerĆon the AWG2005, follow these steps:

How to Power On

1. Set the PRINCIPAL POWER SWITCH (on the back of the AWG2005) to

the ON position. This switch is the main power switch; it routes power to

the standby circuit in the AWG2005.

2. Then, press the ON/STBY (standby) switch on the front (lowerĆleft corĆ

ner) of the AWG2005. This switch applies power to the remaining circuits

of the AWG2005. Allow at least 20 minutes for the AWG2005 to warm up.

WARNING

To avoid personal shock hazard, turn off both the ON/STBY switch

and the PRINCIPAL POWER SWITCH before servicing. The PRINCIĆ

PAL POWER SWITCH on the rear panel is the true power disconĆ

nect switch. The ON/STBY (standby) switch simply toggles

operation on and off. When connected to a power source and when

the PRINCIPAL POWER SWITCH is on, the internal power supplies

and much ofthe other circuitry ofthe AWG2005 remain energized

regardless ofthe setting ofthe ON/STBY switch.

To avoid personal shock hazard, set the PRINCIPAL POWER

SWITCH off before connecting or disconnecting the line cord to or

from the power source.

At powerĆon, the AWG2005 performs internal startĆup diagnostics. These

diagnostics check internal circuit function and report any failures. In addiĆ

tion, you can initiate internal diagnostics; these diagnostics differ from the

startĆup diagnostics in that they do more extensive memory checking.

Internal Diagnostics

Routines

The AWG2005 also contains internal calibration routines, which check

internal circuit function and adjust calibration constants. Run these calibraĆ

tion routines whenever the AWG2005 undergoes a temperature change. For

Instructions for Operation

instance, run the calibration routines after the AWG2005 warms up at powerĆ

on. This warmup period and subsequent calibration assures AWG2005

operation at optimum performance levels.

The AWG2005 uses a combination of frontĆpanel buttons, keys, a knob, and

onĆscreen menus to control generator functions. Some frontĆpanel controls

select menus and manipulate menu items. Others enter values and units,

allow manual triggering, and turn on/off AWG2005 output. OnĆscreen graphĆ

ics show various aspects of the current AWG2005 configuration.

User Interface

OnĆscreen menus set all AWG2005 functions except manual triggering and

output control. Main menus provide access to lowerĆlevel nested submenus.

Buttons in the center of the front panel select the main menus.

When you select a menu, the display shows the items controlled by that

menu and numeric values currently in effect. Buttons around the display

select lowerĆlevel menus, change menu selections, modify numeric values

and units, and execute functions.

Instructions for Operation

The AWG2005 operation is primarily controlled by means of menus that

correspond to the SETUP, MODE, EDIT, LOAD/SAVE and UTILITY buttons in

the MENU column. To display one of these main menus on the screen, push

the corresponding button. The button LED indicates which menu is currently

selected. Refer to the User Manual for more details concerning these meĆ

nus. The F.G button under the MENU column selects function generator

operation.

Menus

SETUP Menu Ċ The SETUP menu sets the following waveform output

parameters for each channel: clock source and frequency, waveform or

sequence file selection, operation, filter, amplitude, and offset.

MODE Menu Ċ This menu sets the operation output mode. The

operation modes are the trigger modes (Cont, Triggered and Gated)

and the modes which display a waveform in sequence for each trigger

(Waveform Advance and Autostep modes). This menu also has an item

for setting the system configure to either master or slave.

EDIT Menu Ċ The EDIT menu allows you to edit an existing file saved

in internal memory or to create a new file. To modify files in internal

memory, use one of the four editors, depending on the waveform file

type: waveform edit, sequence edit, equation edit, and autostep edit.

Instruments with Option 05 installed also have a clock sweep editor

which provides linear, log and arbitrary sweep output for clock frequenĆ

cies. Instrument with Option 09 installed have an FFT editor to permit

editing in the frequency domain and a convolution editor to operate the

waveforms convolution in high speed.

LOAD/SAVE Menu Ċ Here are the functions for this menu:

LOAD menu Ċ loads files from the AWG2005 floppy disk drive or

nonvolatile internal memory into internal memory.

SAVE menu Ċ saves files from the AWG2005 internal memory onto

a floppy disk or into nonvolatile internal memory.

UTILITY Menu Ċ Use this menu to rename or delete files saved in the

floppy disk or internal nonvolatile memory, to set the parameters of GPIB

or RSĆ232ĆC, to set AWG2005 date and time, to change display brightĆ

ness, to set the catalog order, to set the system configure, to set the

hardcopy port and format, to check interface status, and to execute

internal diagnosis and calibration routines.

The AWG2005 generates waveform output from four different types of waveĆ

form files:

Waveform Files

AWG2005 Service Manual

2Ć11

Download from Www.Somanuals.com. All Manuals Search And Download.

Instructions for Operation

Waveform data file (filename.WFM). This is the basicwaveform data file.

It contains the waveform data that the AWG2005 loads into memory and

reads when generating waveform output. The data in this kind of file can

be created using the waveform editor, generated from equations made

using the equation editor, transferred in over an interface, or directly

transferred in from certain Tektronix instruments. In addition, the waveĆ

form editor displays the data in a waveform data file in three formats:

graphical, table, and timing.

Waveform equation file (filename.EQU). The waveform equation file

contains equations that express waveform characteristics. Compilation

of the waveform equation file generates a waveform data file. The

AWG2005 generates the waveform output from this file.

Waveform sequence file (filename.SEQ). The waveform sequence file

specifies a series of waveform data files. When the AWG2005 executes a

waveform sequence file, it sequentially generates waveforms from each

waveform data file, in the order specified.

Waveform autostep file (filename.AST). The waveform autostep file speciĆ

fies a series of waveform data files and/or waveform sequence files.

When the AWG2005 executes a waveform autostep file, it generates the

waveform for the first file specified. Then it waits for a trigger before

generating from the next specified file. The autostep file includes output

conditions for each channel.

The AWG2005 has both internal memory and internal nonvolatile memory

(NVRam) for waveform file storage. The AWG2005 generates waveforms

from files residing in internal memory. To save a file that is in internal

memory, copy it to nonvolatile memory or floppy disk. Only nonvolatile

memory retains files at powerĆoff.

Waveform Storage

and I/O

The AWG2005 also has a floppyĆdisk drive for loading files from floppy disk

into internal memory or internal nonvolatile memory and for saving files from

either memory to floppy disk. The disk drive accepts 3.5Ćinch MSĆDOSĆforĆ

matted floppy disks.

The following steps explain how to load files from a floppy disk into internal

memory.

Loading Files

1. Push the LOAD/SAVE button in the MENU column.

2. Turn the disk so the side with the arrow is on top; insert the disk into the

AWG2005 floppy disk drive.

Instructions for Operation

The following explains each item in the bottom menu.

Clock Ċ This item sets the clock source and clock frequency. The

clock source can be set to either internal or external.

The clock period is the time between the data points for the waveĆ

form created. Therefore, the product of the clock period and the

number of waveform points is the waveform or sequence period. For

example, if the clock frequency is 1 MHz (period of 1 µs) and there

are 100 waveform points, the waveform period is displayed as 100

ms.

The clock source and clock frequency setting will be applied to all

channels.

Operation Ċ This item performs an arithmeticoperation between

the CH1 waveform and CH2 waveform or external waveform, and

outputs the result at the CH1 output connector. The operations are

addition (Add, External Add) and multiplication (AM, External AM).

Filter Ċ This item selects a filter that restricts the frequency band

for the output channel. Choose a 5, 2, 1 MHz, or 500ĂkHz filter, or

you can select Through (no filter).

Ampl Ċ This selection sets the voltage value for the 12Ćbit, fullĆ

scale, output amplitude on the vertical scale. The amplitude can be

set in steps of 1ĂmV within the range from 0.05ĂV to 10ĂV.

Offset Ċ This item sets the offset level of the output waveform. The

offset can be set in steps of 5ĂmV within the range ±5ĂV.

Operation Mode Settings

The MODE menu initiates the waveform output with the output conditions

set using the SETUP menu.

1. Push the MODE button in the MENU column. The MODE menu in

Figure 2Ć6 appears.

2. Select the operation mode from the bottom menu. The operation modes

are Cont, Triggered, Gated, Waveform Advance, and Autostep.

In all modes except Cont, the trigger or gate signal source can be the

external signal applied to the TRIGGER INPUT connector or can be

generated by pushing the front panel TRIGGER MANUAL button. The

following text describes the individual modes.

Cont Mode Ċ When you push the Cont button, the AWG2005

immediately outputs the specified waveform or sequence waveform

continuously.

Instructions for Operation

Figure 2Ć6:ăMODE Menu

Triggered Mode Ċ Intriggered mode, the AWG2005 outputs the

specified waveform or sequence waveform once, when a trigger

occurs.

Gated Mode Ċ In gated mode, the gate signal controls the waveĆ

form or sequence output.

As long as the front panel MANUAL button is pushed, (or the gating

signal is high) the AWG2005 outputs the specified waveform or

sequence. When the MANUAL button is released (or the gating

signal goes low), the waveform output stops. When the MANUAL

buttonis pushed again, the output resumes from the level at which

the waveform or sequence output stopped.

Waveform Advance Mode Ċ Whena sequence file has been

designated in the SETUP menu, Waveform Advance mode is used

to advance a waveform in sequence each time a trigger is received.

The waveform output conditions in waveform advance mode can be

set to either Continuous or Step depending on the selection for the

Run side menu item.

2Ć16

Instructions for Operation

Continuous Ċ In this mode, the first waveform is output over and

over again for each channel when a trigger signal is received. When

the next trigger signal is received, output of the first waveform stops

after the end point of that waveform and then the second waveform

is output in the same manner. The next waveform is not started at

the moment a trigger is received, but rather at the completion of the

previous waveform.

In this way, waveforms are output for each channel one by one in

sequence each time a trigger signal is received. When a trigger

signal is received while output of the last waveform is in progress,

the output stops at the end point of that waveform and then the

process begins again from output of the first waveform.

Step Ċ In this mode, the first waveform is output on each channel

when a trigger signal is received, but only for the number of times

set with Repeat in the sequence editor. The next waveform is output

when the next trigger signal is received. Other operations are the

same as Continuous output.

Autostep Mode Ċ Use Autostepmode to start an Autostepfile

created with the EDIT menu Autostepeditor. An Autostepfile stores

a program that specifies a waveform or sequence file (including

output parameters) for each channel for each step.

Autostepmode resembles Waveform Advance mode in which each

time a trigger is received, the display advances one waveform.

However, in this mode the output parameters for each waveform

change as well. The operating mode for each step can be set with

the waveform output conditions to either Continuous or Step, as in

the case of Waveform Advance mode. Just as in other operating

modes, the Autostepmode trigger signal can be generated from the

external trigger signal or by pressing the front panel MANUAL butĆ

ton.

Continuous Ċ In this mode the programmed Step:1 waveform is

output over and over again when a trigger signal is received. When

the next trigger signal is received output of the Step:1 waveform

stops after the end point of that waveform and then the Step:2

waveform is output in the same manner. The waveform is started at

the moment a trigger is received.

In this way, the current waveforms advance for each channel one by

one in sequence each time a trigger signal is received. When a

trigger signal is received while output of the last waveform in the

step is in progress, the output stops at the end point of that waveĆ

form and then the process begins again from output of the Step:1

waveform.

Instructions for Operation

Step Ċ When a trigger signal is received, the Step:1 waveform for

each channel is output once. When the next trigger signal is reĆ

ceived, the Step:2 waveform is output (once). When the next trigger

signal is received while waveform output is in progress, output stops

after the end point of that waveform and then the waveform for the

next step is output.

3. Set the trigger (gate) conditions for the external trigger (gate) source.

The external trigger (gate) signal is input from the TRIGGER INPUT

connector on the front panel. The input impedance is 10 kW and the

maximum input voltageis "10 V.

When an operating mode other than Cont is selected, the AWG2005

displays a side menu for selecting the trigger (gate) conditions for

the external trigger (gate) source. The following describes each of

these items.

Slope Ċ This item sets the slope for external trigger signals. To

select a positive or negative slope, push the side menu Slope butĆ

ton. For a positiveslope, theAWG2005 applies thetrigger at the

rising edge of the external trigger signal; for a negative slope, the

trigger is applied at the falling edge of the external trigger signal.

Polarity (Gated Mode) Ċ This item sets the polarity for the gate

that outputs the waveform or sequence based on the level of the

external gate signal. To set the polarity, push the side menu Polarity

button. For a positivepolarity, theAWG2005 outputs thewaveform

or sequence waveform while the gate signal level is higher than the

gate level parameter set with the side menu Level item. For negative

polarity, waveform output occurs while the gate signal level is lower.

Level Ċ This item sets the external trigger (gate) signal level. To set

this parameter push the side menu Level button, then use the nuĆ

meric keys or the general purpose knob to change the value. The

trigger (gate) level can be set in steps of 0.1ĂV within the range from

-5.0ĂV to 5.0ĂV.

Theory of Operation

This section describes the basic operation ofthe major circuit blocks or

modules in the AWG2005. Section 9, Diagrams, includes two block diaĆ

grams and an interconnect diagram. Figure 9Ć1 shows the modules and

functional blocks of the AWG2005 with Option 02, 04, 05 and 09 installed.

Figure 9Ć2 shows how the modules interconnect.

The module overview describes the basic operation ofeach functional circuit

block.

Module Overview

The AWG2005 Arbitrary Waveform Generator is a portable, twoĆ or fourĆ

channel instrument. For each channel, the AWG2005 reads the digital waveĆ

form data loaded into its waveform memory. The point rate clock determines

the rate at which the data is read. The AWG2005 converts the data from

digital to analog format and outputs the resulting arbitrary waveform.

Clock Oscillator(A1 Clock Board)

The clock circuit is a PLL oscillator that uses a 12.8 MHz reference crystal. It

supplies a point rate clock that is adjustable from 20 MHz to 0.01 Hz for

reading data from channel waveform memory.

When an external clock source is selected, the external clock signal is

passed directly through to the Clock board and used for reading waveform

data in memory.

Clock Sweep Oscillator(A31 Clock Sweep Board)

In addition to the description for the Clock Sweep Oscillator, it provides the

clock sweep from 20 MHz to 0.03 Hz.

Sequencer(A2 AWG Board)

This sequencer block controls the waveform memory addresses read out

according to the contents ofa sequence file.

Waveform Memory (A2 AWG Board)

Self Tests

This subsection describes how to use AWG2005 internal selfĆtest routines.

No equipment is required to do these procedures. The self tests include

these internal routines:

Diagnostics

This selfĆtest procedure uses internal routines to verify that the

AWG2005 functions, and passes the internal circuit tests.

Calibration

The second procedure checks the AWG2005 internal calibration

constants and changes them if needed.

The internal diagnostic routines check AWG2005 characteristics such as

amplitude, offset, trigger level, clock, filters and attenuation.

Diagnostics

The AWG2005 automatically performs the internal diagnostics at powerĆon;

you can also run the internal diagnostics using the menu selections deĆ

scribed in this procedure. The difference between these two methods of

initiating the diagnostics is that the menu method does more detailed

memory checking than the powerĆon method.

Equipment Required: None.

Prerequisites: Power on the AWG2005 and allow a twentyĆminute warmup

period before doing this procedure.

Procedure:

1. Verify that internal diagnostics pass: Do the following substeps to verify

passing internal diagnostics.

a. Display the diagnostics menu and select all tests: Push

UTILITY! Diag/Cal! Diagnostics xxxx! All. See the menu in

Figure 4Ć1.

The Diagnostics column on the left shows the tests available for

diagnostics. In addition to selecting all of the tests shown for DiagĆ

nostics, you can select only the test(s) you want to run using the

general purpose knob. In Figure 4Ć1, the symbol to the left of Cpu

indicates that test is one of the tests selected.

Before Maintenance

Preventing ESD

CAUTION

Static discharge can damage any semiconductor component in the

AWG2005.

Precautions

When performing service which requires internal access to the AWG2005,

follow these precautions to avoid damaging internal modules and their

components due to electrostatic discharge (ESD).

1. Minimize handling of staticĆsensitive modules.

2. Transport andstore staticĆsensitive modules in their staticĆprotected

containers or on a metal rail. Label any package that contains staticĆsenĆ

sitive modules.

3. Discharge the static voltage from your body by wearing a grounded

antistatic wrist strap while handling these modules. Only service staticĆ

sensitive modules at a staticĆfree work station.

4. Do not remove the AWG2005 cabinet unless you have met precaution

number 3, above. Consider all internal modules staticĆsensitive.

5. Do not allow anything capable of generating or holding a static charge

on the work station surface.

6. Handle circuit boards by the edges when possible.

7. Do not slide the modules over any surface.

8. Avoid handling modules in areas that have a floor or workĆsurface coverĆ

ing capable of generating a static charge.

9. Do not use highĆvelocity compressedair when cleaning dust from

modules.

Susceptibility to ESD

Inspection and Cleaning

This subsection describes how to determine whether the AWG2005 needs

cleaning, and how to do the cleaning. Inspection and cleaning are prevenĆ

tive maintenance procedures. When done regularly, preventive maintenance

may prevent AWG2005 malfunction and enhance reliability.

Preventive maintenance consists of visually inspecting and cleaning the

AWG2005 and using general care when operating it.

How often to do maintenance depends on the severity of the environment in

which the AWG2005 operates.

The cabinet helps keep dust out of the AWG2005 and is a major component

of the instrument cooling system. The cabinet should normally be in place

when operating the AWG2005. The AWG2005 front cover (optional accessoĆ

ry) protects the front panel and display from dust and damage. Install it

when storing or transporting the instrument.

General Care

Inspect and clean the AWG2005 as operating conditions require. The collecĆ

tion of dirt on components inside can cause them to overheat and break

down. (Dirt acts as an insulating blanket, preventing efficient heat dissipaĆ

tion.) Dirt also provides an electrical conduction path that can cause an

instrument failure, especially under highĆhumidity conditions.

Inspection and

Cleaning Procedures

WARNING

To avoid personal injury or death due to electric shock, unplug the

power cord from the line voltage source before cleaning the

AWG2005.

Inspection and Cleaning

CAUTION

To prevent damaging the plastics used in the AWG2005 do not use

chemical cleaning agents. Use only deionized water when cleaning

the menu buttons or frontĆpanel buttons. Use a ethyl alcohol soluĆ

tion asa cleaner, and rinse with deionized water.

To prevent damaging AWG2005 components, do not use highĆpresĆ

sure compressed air when cleaning dust from the interior of the

AWG2005. (High pressure air can cause electrostatic discharge.)

Instead, use low pressure compressed air (about 9 psi).

Inspection Ċ Exterior

Inspect the outside of the AWG2005 for damage, wear, and missing parts,

using Table 6Ć2 as a guide. If the AWG2005 appears to have been dropped

or otherwise abused, check it thoroughly to verify correct operationand

performance. Repair any defects that may cause personal injury or lead to

further damage to the AWG2005.

Troubleshooting

The AWG2005 has internal diagnostics that verify circuit functionality. The

AWG2005 automatically executes the internal diagnostics at powerĆon. You

can also run the internal diagnostics by using the UTILITY menu. See

Checking Diagnostics Tests below. The difference between the two methods

of running the internal diagnostics routine is that the powerĆon method does

not do as much memory checking.

AWG2005

Diagnostics

If the internal diagnostics indicate a test in the internal diagnostics failed,

use the troubleshooting procedures in this subsection to determine which

module to replace.

Checking Diagnostics Tests

Prerequisites Ċ Power on the AWG2005 and allow a 20 minute warmup

before doing this procedure.

1. Push the UTILITY! Diag/Cal! Diagnostics

2. Select All with the general purpose knob.

3. Select Execute from the side menu. This executes all the diagnostics

automatically. As each test finishes, the result is displayed on the

screen.

4. Check the diagnostic test results. If any test failed, go to TroubleshootĆ

ing Procedure 4 Ċ Module Isolation on page 6Ć68. The table in the

flowchart shows which module is related to each diagnostic test. If the

tests pass but there is still a problem, go to the Primary Troubleshooting

Procedure on page 6Ć59.

Pins other than above are connected to ground. The pin assignments are identical for both

CH1 and CH2.

Operation

Basically, operations are in correspondence with analogoutput for the

AWG2005 arbitrary waveform generator. When a waveform is not being

output, the waveform's initial data may be output to the connector. At this

time, the clock is not generated.

When startingthe waveform output, the clock is generated and the data is

updated.

NOTE

Excess output can be generated in the data clock (see Figure 7Ć3)

when loading a new waveform into waveform memory, when resetĆ

ting the waveform memory, or during the hold off.

Output Circuit and Output Waveform

Figure 7Ć4 shows a diagram of the output circuit. After first passing through

an output resistance of 50 Ω, the buffer output proceeds to the output conĆ

nectors. The AWG2005 can be used without terminating the receiving (user)

side with a resistance of 50 Ω, but when waveform distortion is greater the

50 Ω termination is required.

The skew of the data output is held to "15 ns. The rising and falling times

will depend on the bufferICs, but neitheris greaterthan 4 ns. See Figure

7Ć5. This figure shows the specifications for the waveform at the output

connectorwhen a cable is not being used.

Figure 7Ć5:ăOutput Waveform

If a cable is used these waveforms have transmission distortion. It is necesĆ

sary to latch the data with a clock before using the waveform in actual

circuits at the cable receiving side (user side) and to reproduce the waveĆ

form. Delay the clock with the delay line in order to reproduce the data

reliably (see Figure 7Ć6).

Cable

Option 04 comes with a digital data out cable. The cable connecting the

AWG2005 rear panel output connectors and the user circuit is extremely

critical for operation at the maximum clock frequency. Figure 7Ć7 shows the

digital data out cable provided as a standard accessory and the receiving

connector.

Connector : Female

Figure 7Ć7:ăDigital Data Out Cable

If you use a cable other than the one provided as the standard accessory

the cable must meet the following conditions.

It must be a coaxial cable with a characteristic impedance of 50ĂΩ for all

DATA and CLOCK lines.

Keep cables as short as possible. The acceptable length depends on

the characteristics of the coaxial cable used, but lengths under 1Ămeter

are preferable.
