Agilent Technologies, Inc. assumes no liability for the customer’s failure to
comply with these requirements.
For additional safety precautions, including precautions for making device
measurements in a floating ground configuration, see “To ensure your
safety while using the system" on page 76.
WARNING This is a Safety Class 1 Product (provided with a protective earthing
ground incorporated in the mains supply cord). The mains plug shall
be inserted only in a socket outlet provided with a protective earth
contact. Any interruption of the protective conductor inside or
outside of the product is likely to make the product dangerous.
Intentional interruption is prohibited.
WARNING If this product is not used asspecified, the protection provided by the
equipment could beimpaired. This product must be used only in a
normal condition (in which all means for protection are intact) only.
WARNING DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE. Do not operate
the instrument in the presence of flammable gasesor flames.
WARNING DO NOT REMOVE THE INSTRUMENT COVER. Operating personnel
must not remove instrument covers. Component replacement and
internal adjustments must be made only by qualified service
personnel. Instruments that appear damaged or defective should be
made inoperative and secured against unintended operation until
they can be repaired by qualified service personnel.
WARNING Installing additional instruments may destabilize the rack cabinet.
WARNING Installing additional instruments into the cabinet electrical system
could produce excessive leakage current. If the protective earth
conductor is interrupted or faulted, the user risks serious injury or
death.

Mains power
Ground the system
Before applying power
CAUTION The mains cable shall be permanently connected to the premise circuit
breaker or connected using an agency approved twist-lock connector.
WARNING To minimize shock hazard, the rack cabinet must be connected to an
electrical protective earth ground. The power distribution unit (PDU)
must be connected to the AC power mains through a groundedpower
cable, with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet.
WARNING Any interruption of the protective (grounding) conductor or
disconnection of the protective earth terminal will cause a potential
shock hazard that could result in personal injury.
CAUTION Verify that the product is set to match the available line voltage, the
correct fuse is installed, and all safety precautions are taken. Before
applying power, note the product’s external markings described in
Table A, “Safety Symbols,” on page 4 and Table B, “Instrument
Markings,” on page 5.
CAUTION It is recommended that the premise wiringcontain an adequate circuit
breaker for system protection.

Performance Modeling System Configuration Overview
The standard Agilent 85225F performance modeling system measures the
DC and RF performance of active and passive devices. You may configure
the Agilent 85225F performance modeling system to measure CV and 1/f
noise with the addition of optional instrumentation and IC- CAP 1/f noise
measurement modules.
For RF and DC performance measurement system configurations, see “RF
and DC Measurement System Configuration" on page 19.
For CV, RF, and DC performance measurement system configurations, see
“CV, RF, and DC Measurement System Configuration" on page 29.
For 1/f noise, CV, RF, and DC performance measurement system
configurations, see “1/f Noise, CV, RF, and DC Measurement System
Configuration" on page 45.

RF and DC Measurement System Configuration
In conjunction with a compatible controller running 85190- Series IC- CAP
software, the Agilent 85225F performance modeling system measures the
DC and RF 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 is the integration of
rack- mounted RF and DC subsystems, bias networks, and a system
controller*, as shown in Figure 1†.
* The systemcontroller is not included and must be provided.
† This block diagram shows a system with an Agilent 4156C as the DC subsystem. Other instrumentation may
be used. See “The DC Subsystem" on page 20.
Figure 1 System Block Diagram

20 Installation and User’s Guide
1IntroducingtheAgilent 85225F Performance ModelingSystem
The RF Subsystem
S- parameter device characterization is provided by the RF subsystem.
The RF subsystem contains the Agilent E8364B PNA Series vector network
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
resolution source/monitor units).
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.
