analyzer.
Its integrated synthesizer supplies a swept or CW RF source signal from
10 MHz* to 50 GHz.
The integrated test set separates the RF source signal into reference and
test signals, and provides RF connection via cables and adapters to the
external bias networks.

The DC Subsystem
Precision DC characterization and bias for the S- parameter measurements
are provided by one of the following three DC subsystems.
The DC subsystem may contain one of the following three instruments.

Agilent 4156C Precision Semiconductor Parameter Analyzer
The Agilent 4156C precision semiconductor parameter analyzer provides
DC force (supply) and sense (measure) capability from its HRSMUs (high

Optionally, the Agilent 4156C may be configured with a 41501B SMU PGU
expander is connected to and controlled by the 4156C via the expander
box interface. The 41501B provides a GNDU (active ground unit) and,
depending on option configuration, an HPSMU (high- power source/monitor
unit), two MPSMUs (medium- power source monitor units), and/or two
PGUs (pulse generator units).
The DC signals are routed through feedthrough panels via triaxial cables to
the bias networks.

Agilent E5260A 8-Slot High Speed Parametric Measurement Mainframe
The Agilent E5260A provides DC force (supply) and sense (measure)
capability from its plug- in source/monitor units.
The Agilent E5290A plug- in high speed high power source/monitor unit
provides up to 200 volts of potential and 1 amp of current to the device
under test.
The Agilent E5291A plug- in high speed medium power source/monitor unit
provides up to 100 volts of potential and 200 milliamps of current to the
device under test.
* Due to the minimum operating frequency of the bias networks, the performance modeling system low end
frequency range is 45 MHz.

Installation and User’s Guide

Introducing the Agilent 85225F Performance Modeling System

Agilent E5270B 8-Slot Precision Parametric Measurement Mainframe
The Agilent E5270B provides DC force (supply) and sense (measure)
capability from its plug- in source/monitor units.
The Agilent E5280A plug- in high power source/monitor unit provides up
to 200 volts of potential and 1 amp of current to the device under test.
The Agilent E5281A plug- in medium power source/monitor unit provides
up to 100 volts of potential and 200 milliamps of current to the device
under test.

CAU TI O N

Exposing the bias networks to currents greater than 500 milliamps or voltages
greater than 40 volts will result in severe damage. Do not exceed these values
while using the bias networks. Remove the bias networks from the circuit if
greater voltages or currents are required.

The Bias Networks
The Agilent 11612V Option K11 and K21 bias networks combine the DC
and RF signals and apply them simultaneously to the device under test
(DUT). The bias networks are configured with 2.4 mm DC/RF output
connectors for connection to a DUT, a test fixture, or probe station, as
shown in Figure 21 on page 54.

CV, RF, and DC Measurement System Configuration
With the addition of a precision LCR meter, the Agilent 85225F
performance modeling system measures the DC, RF, and CV performance
of active and passive devices. The IC- CAP software then extracts the
device parameters and displays the results.
The Agilent 85225F performance modeling system for CV, RF, and DC
measurement is the integration of rack- mounted RF, DC, and CV
subsystems, bias networks, and a system controller, as shown in Figure 8.
Figure 8

System Block Diagram

Installation and User’s Guide

Introducing the Agilent 85225F Performance Modeling System

The CV Subsystem
The Agilent 4284A precision LCR meter provides a wide 20 Hz to 1 MHz
test frequency range and superior test- signal performance, allowing CV
testing to the most commonly- used test standards, such as IEC/MIL, and
under conditions that simulate the intended application.
Optionally, the system can be configured with the Agilent E5250A low
leakage switch mainframe. The Agilent E5250A is used for precise
parametric test. It improves measurement efficiency by eliminating the
need to manually change the probe positions on a manual probe station.
The E5250A is used to route signals from the DC and CV subsystems to
the probe card cable, and on to the probe card and probe station.

Component Integration
System component integration is performed at the Agilent Technologies
factory. The individual components are placed into the rack, and the
required cabling is connected between the instruments.
After factory integration, the system is tested to verify functional
performance.
The Agilent 85225F performance modeling system includes the following
components, as shown in Figure 18 on page 49:
• Agilent E8364B PNA Series vector network analyzer
• Agilent 4156C precision semiconductor parameter analyzer (or
optionally Agilent E5260A or E5270B)
• Agilent 11612V Option K11 bias network (port 1)
• Agilent 11612V Option K21 bias network (port 2)
• Agilent 4284A precision LCR meter
• Agilent 85133F flexible test port cable set
• Agilent E3661B 1.6 meter rack cabinet
• filler panels, feedthrough panels, work surface, cables, and adapters
System front panel connections are listed in Table 10 on page 50 and
illustrated in Figure 19 on page 51.

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.

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.

WA RN ING

Failure to comply with the following precautionary safety instructions prior to
operating the system could result in serious injury or death.
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.

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.

WA RN ING

A potential shock hazard exists when the shorting bar is disconnected for
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.

NO TE

The circuit common is not connected through the bias networks.

Read “Precautions for Performing Floating- Ground Measurements" on
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.
2 Connect the external ground to the CIRCUIT COMMON of the DC subsystem.

Verifying System Functionality

To choose a verification process
System functionality can be verified using several different processes,
depending on the level (system or subsystem) of functional verification
required and the available tools.
The procedure provided in “Performing the System Functional Verification
Test" on page 95 verifies that all of the system instruments interface
correctly, and that the system can make software- driven measurements
using a controller running the IC- CAP software.
Manual functional verification procedures for DC, RF, CV, and 1/f noise
subsystem components can be found in:
• Appendix B, “DC Subsystem Functional Verification Test,”
starting on page 119
• Appendix C, “RF Subsystem Functional Verification Test,”

Verifying System Functionality

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.

complete, IC-CAP displays plots of the
S12/21, 20×log10 of the S21
magnitude, and S21 phase.**
IC-CAP also lists the attenuator’s
resistance values. The error between
measured and simulated data should
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.

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.

Understanding the Bias Networks

Features
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

Do not exceed the maximum ratings of the bias networks. Failure to
comply can result in severe damage.

139

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
oscillation of the device under test. Refer to Figure 24.

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.
