The LAN/ GPIB Gateway
The Agilent E5810A LAN/GPIB gateway provides access to the system’s
GPIB instrumentation over an existing local area network. It allows the
use of SICL- or VISA-based applications designed for GPIB over the LAN
without modifying the application beyond a simple address change.
The gateway is a combination of hardware and SICL/VISA software. It
uses client/server technology to extend the standard remotely over the
LAN, allowing remote control from an alternative, more convenient, or
safer location.

RF Subsystem Performance Specifications
The overall performance of a network analyzer is dependent on the
individual instruments, system configuration, user- defined operating
conditions, measurement calibration, and cables.
In any high-frequency measurement, residual errors contribute
uncertainties to the results.
When the system is configured with a probe station, microwave probes, on-wafer
calibration standards, or test fixtures, additional uncertainties are contributed to the
measurement results. Refer to the manufacturer’s documentation for information on probe
station or test fixture characteristics.

To ensure your safety while using the system
This product has been designed and tested in accordance with
international standards. Bias current and voltage are supplied to the DUT
from the DC subsystem. This instrument can force dangerous voltages to
the FORCE, SENSE, and GUARD connectors. DC subsystem is connected to
the device through the bias networks and test fixture or probe station.
Failure to comply with the following precautionary safety instructions prior to
operating the system could result in serious injury or death.
WARNING
With some installed options, the Agilent 4156C or Agilent E5260A/ 70B used in
this system can supply voltages up to ±200 volts DC. Depending on operating
conditions, hazardous voltages can be present at points in the system that
could potentially come in contact with the system operator.
Before operating the system, follow these steps to ensure your safety.

indicator is not lit.
• Deactivate the standby mode (if used) by
pressing the Standby key and confirming
that the Standby indicator is not lit.
• Confirm that the HIGH VOLTAGE
indicator is not lit.
• Open the interlock connection.
6 Never use replacement
fuses with incorrect
ratings.
a After finding the cause of failure, replace
component fuses with fuses of the same
current rating and of the type specified in
the instrument’s product documentation.
• Failure to use correctly rated fuses
could result in a fire hazard and
damage to the equipment.
7 Install the instrument so
that the ON/ OFF switch is
readily identifiable and
easily reached by the
operator.
• The ON/ OFF switch is the system
disconnecting device. It disconnects
the mains circuit from the mains supply
before other parts of the instrument.
• Alternately, an externally installed
switch or circuit breaker (readily
identifiable and easily reached by the
operator) may be used as a
disconnection device.

Precautions for Performing Floating-Ground Measurements
IC- CAP measurements can be performed with the device in a
floating- ground configuration. This prevents ground- loop noise and, in the
case of a bipolar junction transistor, damage to the device under test.
A floating- ground configuration is created by removing the shorting bar
that connects the CIRCUIT COMMON and CHASSIS GROUND terminals.
A potential shock hazard exists when the shorting bar is disconnected for
WARNING
floating-ground measurements. Do not touch any of the DC subsystem rear
panel connectors while a floating ground measurement is in progress.
If you are making measurements in a floating-ground configuration, ensure
that the shorting bar is disconnected between the CIRCUIT COMMON and
CHASSIS GROUND terminals.
To perform floating-ground measurements
When floating ground measurements are necessary, remove the rear front
panel shorting bar connecting the CIRCUIT COMMON and CHASSIS
GROUND terminals.
When the shorting bar is removed, you must drive the DUT circuit
common with either an SMU, GNDU, or by connecting directly to the DC
subsystem circuit common. The circuit common can be found at the DUT
ends of the SMU and GNDU cables.
The circuit common is not connected through the bias networks.
NOTE
page 78, then follow these steps to connect the CIRCUIT COMMON to an
external ground.
To connect an external ground to the circuit common
Step
1 Remove the shorting bar connecting the CIRCUIT COMMON and CHASSIS
GROUND terminals.

Understanding the System Functional Verification Test
The system functional verification test is a standard IC-CAP measurement
and simulation procedure. The system performs DC and S-parameter
extraction, optimization, and simulation using a fixed 10 dB attenuator as
the device under test (DUT).
The procedure provided in “Performing the System Functional Verification
Test” confirms:
• the IC-CAP software can communicate with and control the system
instrumentation via GPIB (through the LAN/GPIB gateway, if so
configured)
• the system can make measurements and display the results
• the IC-CAP software can simulate data
• the IC-CAP software can converge the simulated data with the
extracted (measured) data
The system applies forward and reverse current to the attenuator and
monitors voltage at the attenuator’s input and output. IC-CAP then uses
the measured data to model the device-intrinsic resistances and
transmission line delay.

resistance values. The error between

be less than 2%.
• The error between the measured and
simulated S21 phase data should be
less than 2%.
• The value for T1.TD is the transmission
time through the attenuator, modeled
as transmission line delay. This value
(typically in the femtosecond to
nanosecond range) depends on the
length of the attenuator.
• The S21 magnitude and the S12/ S21
plots, of less significance, are included
for your interest.
• The S21 simulated trace is determined
from the measured DC resistances, and
therefore is not expected to converge
with the measured data over the full
frequency range. However, the
measured S21 data will show a normal
frequency response variation.
• The S12/ S21 plot (also displayed on
the network analyzer) confirms that the
system is capable of making forward
and reverse transmission
measurements.

Step
Action
Notes
1 Inspect device
connections for foreign
materials or connector
damage.
a Prior to connecting the DUT, inspect the
bias network and semi-rigid RF cable
connectors for foreign materials or
damage.
• Before using connectors for a critical
measurement, inspect the connector
interfaces with a microscope (~20X).
Look for dirt, contaminants, dented or
scratched outer conductor mating
surfaces, and damaged center
conductors.
b Replace any damaged connectors.
2 Clean the connectors.
a Remove the systems power cord from the
power supply or place the supply breaker in
the tripped position.
• Be careful not to let the alcohol get on
the insulator bead, as this may damage
the bead.
b Move the connectors to a well ventilated
area.
c Use a swab dipped in clean isopropyl
alcohol to cleanse the outer conductor
mating surfaces and the ends of the center
conductors.
d Blow off the remaining alcohol with clean
compressed air.
e Allow adequate time for the alcohol fumes
to disperse before activating the system.
• Be careful not to exert too much force
on the center conductors, as they may
be damaged.
• Compressed air can reduce the
temperature of connectors
dramatically, and this can have a
significant effect upon the performance
of calibration and verification
components.
• If the connector components being
cleaned are to be used in a critical
measurement application, allow the
temperature of these components to
stabilize prior to use.
3 Ensure proper system
a Switch on line power to all of the system
components.
b Allow at least 1 hour warm-up prior to
making measurements.
• Do not switch off line power to the
system unless the system will not be
used for an extended period of time.

Enhancing Measurement Accuracy
Understanding System Measurement Calibration
Measurement accuracy is degraded by the effects of three different types
of measurement errors: systemic, drift, and random.
Systemic errors are caused by imperfection in the test equipment and test
setup.
Drift errors occur when a test system’s performance changes after a
calibration has been performed. Drift errors are caused primarily by
variations in the ambient temperature of the measurement environment.
Random errors are caused by instrument noise (sampler noise, IF noise
floor, etc.), switch repeatability and connector repeatability. These errors
vary randomly as a function of time.
You can compensate for systemic and drift errors by performing a system
measurement calibration prior to measuring a device. (Performing a
measurement calibration has no effect upon random errors.)
To increase the accuracy of your measurements, perform a system
measurement calibration before performing device measurements. Repeat
the measurement calibration if the ambient temperature of the
measurement environment has deviated 1°C since the last measurement
calibration.
This procedure performs a modified full 2-port measurement calibration to
remove the following errors:
• Directivity
• Source- load match
• Reflection tracking
• Transmission tracking
The isolation calibration (crosstalk correction) has been omitted. Isolation
calibration is only required when measuring high- isolation devices such as
a switch in the open position or high- dynamic range devices such as
filters with a high level of rejection.
Required Tools
• Agilent 85225F performance modeling system
• Agilent 85056A 2.4 mm calibration kit, or

Using the Agilent 11612V K11 and K21 bias networks, you can
simultaneously supply DC bias and RF energy to the device under test
(without the need to use patch cables or adapters) to make convenient
and accurate DC and S-parameter measurements.
Each bias network provides:
• floating triaxial FORCE connection to input current or voltage
• floating triaxial SENSE connection to monitor voltage or current
• floating triaxial GNDU connection to implement an active ground
• 2.4 mm coaxial RF input
• 2.4 mm coaxial combined RF/DC output
• device bias oscillation suppression

Understanding the Bias Networks
Operation
Each bias network includes two bias tees, one for force and one for sense.
The force bias tee includes a capacitor in the RF signal path that functions
as a high-pass filter and DC block. The sense bias tee provides a through
path for DC. Both force and sense tees include resistive-capacitive
oscillation suppression circuitry to help prevent low frequency bias

Dynamic Range
System dynamic range is calculated as the difference between the noise
floor and the source maximum output power. Reflection measurements are
limited by directivity. Therefore, system dynamic range only applies to
transmission measurements.

Measurement Uncertainty
Measurement uncertainty curves utilize an RSS (Root Sum Square) model
for the contribution of random errors such as noise and typical connector
and test set switch repeatabilities. These are combined with a worst- case
model for the contributions of dynamic accuracy and residual systemic
errors.
Curves show the worst-case magnitude and phase uncertainty for
reflection and transmission measurements, using the specified cal kit, with
10 Hz IF bandwidth, and no averaging during the measurement.
