Transporting the Oscilloscope
When transporting the oscilloscope, wrap the cord around the handle as shown
below. Use the supplied cord retainer if the power plug does not have a
molded-in retainer. The oscilloscope front cover has a convenient place to store
the Reference Manual.
If you are not using a battery, use the accessory tray in the battery compartment
to store probes and other accessories.
CAUTION. To avoid damage to the disk drive, do not transport the oscilloscope
with a floppy disk in the disk drive.

Operating Information
Connecting Power
To connect a power cord, do these steps:
1. Open the strain relief and slip it over the power cord.
2. Snap the strain relief into its hole in the rear panel of the oscilloscope.
3. Connect the power cord to the power input connector.
You can operate the oscilloscope from a grounded mains supply with line voltage
between 90 VAC and 250 VAC and frequency between 47 Hz and 440 Hz. The
oscilloscope is grounded through the power cord. The line fuse is internal and is
not user replaceable.
Using Battery Power
You can operate the oscilloscope continuously for approximately two hours from
the rechargeable battery pack. A triangle icon in the display ( ) shows when the
battery is in use, a power-plug icon (
) shows when line power is connected,
and a gauge icon ( ) shows the charge level in the battery. The oscilloscope
turns off automatically when the battery runs low; a low-battery message appears
in the display about ten minutes before the automatic shutdown.
NiCad batteries appear to lose capacity if not allowed to occasionally discharge
completely. Every few months, run your oscilloscope until it shuts down and
then recharge the battery completely to keep your battery pack at peak perfor-
mance.
Refer to the General Safety Summary for information about proper nickel-cad-
mium battery disposal.

Operating Information
Operating Safely with
Battery Power
WARNING. To avoid electric shock, always connect the rear-panel ground
terminal to earth ground when operating the instrument from battery power.
For safe operation, the oscilloscope chassis must remain at earth ground potential
even when operating from battery power. Without a connection between the
chassis and earth ground, you can receive a shock from exposed metal on the
chassis if you connect an input to a hazardous voltage (>30 VRMS, >42 Vpk).
Protection against this condition is provided when you attach the Tektronix-sup-
plied grounding wire from the terminal on the rear panel to earth ground. If you
use a different grounding wire, it must be at least 18 gauge.
When you start to use the battery pack, an on-screen message reminds you to
connect the grounding wire between the ground terminal on the rear panel and
earth ground.

Installing an Application Module
CAUTION. To avoid damage to the oscilloscope or application module, observe
the ESD precautions described on page ix.
Optional application modules are available to extend the capability of your
oscilloscope. You can install up to four application modules at one time.
Application modules can go into the two slots with windows in the upper right
corner of the front panel. Two additional slots are located behind the two you can
see. To install an application module, do these steps:
1. Save any oscilloscope settings and/or reference waveforms you want to keep
to floppy disk before doing these steps.
2. Turn the oscilloscope power off.
3. Open the small door in the upper right corner of the front panel.
4. Slide the application module into any available slot with the module contacts
facing the circuit board. If it is necessary to make space for a new application
module, use a small flat-bladed screwdriver in the molded depression on the
end of a module to slide an installed module out of a slot.
NOTE. If you remove an application module, the features provided by the
application module become unavailable. You can reinstall the module to restore
the features.
5. Close the module door.

6. If the application module came with one or more floppy disks, insert the
firmware upgrade floppy disk into the disk drive. If there is more than one
floppy disk, insert firmware upgrade floppy disk number one into the disk
drive.
7. Power on the oscilloscope. The oscilloscope determines whether the
firmware update is necessary. If no firmware update is necessary, the
oscilloscope powers on with no messages. Go to step 9.
8. Push OK Load New Firmware to begin loading the firmware. During the
process, the oscilloscope may instruct you to insert a second floppy disk;
insert the second firmware disk at that time. When the firmware upgrade is
complete, the oscilloscope will restart automatically with the new firmware.
NOTE. If you power off the oscilloscope, eject a floppy disk, or there is a power
outage during the upgrade process, you must power off the oscilloscope and do
the firmware upgrade procedure, starting at step 6, before you can use the
oscilloscope.
9. Remove the floppy disk.

Theory of Operation
Battery Board
The battery board provides the following functions:
Interfaces to the optional battery pack (powers the oscilloscope from the
battery pack or charges the battery pack when the oscilloscope is connected
to AC line).
Turns on AC power to the oscilloscope.
Converts 15 VDC from the power supply to 5 VDC for the main and front
panel boards and ±15 VDC for probe power.
Powers the cooling fan.
Routes 15 VDC from the power supply to the external power connector for
powering external devices.
Main Board
The Main Board module contains the following functions.
Acquisition System
The acquisition system begins with the analog signal path and ends with a
digitized signal in memory. The signal enters a channel input and then passes
through an attenuator and preamplifier. The analog signal from each preamplifier
goes through a sampler and digitizer, a time base controller, and then into
acquisition memory. The analog signal from each preamplifier is also distributed
to a trigger circuit.
Trigger System
The trigger system processes the analog signals from the preamplifiers and sends
trigger information to the time base controller. Advanced trigger functions are
enabled only when the appropriate application modules and supporting software
is installed.
Display System
The display system combines live waveform data from acquisition memory with
menus and text and stores this information in display memory. It then uses this
data to refresh the VGA display module (LCD).
Processor System
The processor system contains a MPC680DC Power PC microprocessor that
controls the entire instrument. The processor system also contains flash ROM,
system RAM, and interfaces to communication modules, the parallel printer port,
and the floppy disk drive.

Theory of Operation
Power Converter
The power converter receives 15 VDC (or battery voltage) from the battery board
and generates voltages for the analog and digital circuitry on the main board.
Display Module
The display module consists of a color liquid crystal display (LCD), a display
driver, a pair of fluorescent back light tubes, and a high-voltage back light power
supply.
Front-Panel Board
Disk Drive
The front-panel board contains a microprocessor that reads the front-panel
buttons and controls and then sends this information to the processor system.
The front-panel board also generates the probe compensation output signal and
provides an interface to the application modules.
The disk drive module consists of a 3.5 inch, IBM format, floppy disk drive. The
disk drive is controlled by circuitry on the Main Board.

Adjustment Procedures
Overview of the Adjustment Process
The oscilloscope is protected from inadvertently changing factory adjustments
by a rear-panel switch. To perform the factory adjustment, you must push and
hold the switch while you power on the oscilloscope.
Before performing adjustment procedures, you must warm up the oscilloscope at
least ten minutes in an ambient temperature between 20° C and 30° C. Adjust-
ments performed prior to warm-up or outside this temperature range may result
in poor performance.
The factory adjustment procedure consists of a series of steps; as you move
through these steps, the oscilloscope display provides instructions that describe
the specific input signal requirements for each step. If the the step passes, the
oscilloscope moves on to the next step. If any step fails, you can repeat the step
or choose to abort the procedure.
NOTE. During some steps, the instrument may appear to be idle for several
minutes while it is processing information internally. Please have patience.
If all steps in the procedure are completed successfully, a “Pass” message is
displayed and the new calibration constants take affect. If the procedure fails for
any reason, the oscilloscope reverts to the previous calibration settings.

Adjustment Procedures
Signal Connections
The adjustment procedure requires three types of equipment setups if you are
adjusting a four-channel oscilloscope, or four types if you are adjusting a
two-channel oscilloscope. For each step of the procedure, the oscilloscope
display indicates which setup is the correct one to use. The equipment setups are
described below.
Apply DC Voltage to
Channels
The first steps require a DC voltage (or zero volts) to be applied simultaneously
to all the channels. A typical on-screen instruction might read:
When you see an instruction similar to this, connect the oscilloscope to the DC
voltage source to all the channels as shown below and then set the DC voltage to
the specified value.

NOTE. If the DC voltage source you are using has an output head, use a
female-to-female BNC adapter and a short BNC cable to make the connection to
the first BNC tee.
When you are given the instruction to apply a 0 V DC signal, turn off or ground
the output of the DC voltage source to be sure that no DC voltage is present.
Apply Pk-Pk Voltage to a
Channel
Later in the procedure, a leveled sine wave needs to be applied to each channel,
one channel at a time. A typical on-screen instruction might read:
When you see an instruction similar to this, connect the leveled sine wave
generator to the specified channel and then set the amplitude and frequency to
the specified values.

about using the oscilloscope.
Preventing ESD
When performing any service which requires internal access to the oscilloscope,
adhere to the following precautions to avoid damaging internal modules and their
components due to electrostatic discharge (ESD).
CAUTION. Static discharge can damage any semiconductor component in this
instrument.
1. Minimize handling of static-sensitive modules.
2. Transport and store static-sensitive modules in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
modules.

Maintenance
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules. Do service of static-sensitive
modules only at a static-free work station.
4. Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
5. Handle circuit boards by the edges when possible.
6. Do not slide the modules over any surface.
7. Avoid handling modules in areas that have a floor or work-surface covering
capable of generating a static charge.
Inspection and Cleaning
This section describes how to inspect for dirt and damage, and how to clean the
oscilloscope. Inspection and cleaning are done as preventive maintenance.
Preventive maintenance, when done regularly, may prevent malfunctions and
enhance reliability.
Preventive maintenance consists of visually inspecting and cleaning the
oscilloscope, and using general care when operating it. How often to do
maintenance depends on the severity of the environment in which the oscillo-
scope is used. A proper time to perform preventive maintenance is just before
adjustment of the oscilloscope.
General Care
Protect the oscilloscope from adverse weather conditions. The oscilloscope is not
waterproof.
Do not store or leave the oscilloscope where the LCD display will be exposed to
direct sunlight for long periods of time.
CAUTION. To avoid damage to the oscilloscope, do not expose it to any sprays,
liquids, or solvents.
Inspection and Cleaning
Procedures
Inspect and clean the oscilloscope as often as operating conditions require. The
collection of dirt on internal components can cause them to overheat and
breakdown. Dirt acts as an insulating blanket, preventing efficient heat dissipa-
tion. Dirt also provides an electrical conduction path that could cause an
oscilloscope failure, especially under high-humidity conditions.
