WARNING
WARNING
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.
If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used only in a
normal condition (in which all means for protection are intact) only.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE. Do not operate
the instrument in the presence of flammable gases or flames.
WARNING
DO NOT REMOVE THE INSTRUMENT COVER. Operating personnel
must not remove instrument covers. Component replacement and
internal adjustments must be m a de only by qualified service
personnel. Instruments that appear damaged or defective should be
made inoperative and se cured against unintended operation until
they can be repaired by qualified service personnel.

6Installation and User’s Guide
Installing additional instrument s may dest abi l ize the rack cabinet.
Installing additional instruments into the ca bine t electrical system
could produce excessive leakage current. If the protective earth
conductor is interrupted or faulted, the user risks serious inj u ry or
death.
Prior to adding any additional instruments, review all wiring and
cooling capabilities to verify adeq uate design margins for nor mal and
under single fault conditions.
Mains power
CAUTION
Ground the system
WARNING
WARNING
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.
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 grounded power
cable, with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet.
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.
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 page4 and Table B, “Instrument
Markings,” on page5.
CAUTION
CAUTION
CAUTION
Installation and User’s Guide7
It is recommended that the premise wiring contain an adequate circuit
breaker for system protection.
To remove power from the cabinet, remove the mains supply from the
premise electrical supply.
Before switching on this system, make sure that the supply voltage is
in the specified range.
CAUTION
Fuses and breakers
The front panel LINE switch disconnects the mains circuit from the
mains supply. Ho wev e r, the mains supply to the po wer d is tr ib ut io n u n it

WARNING
Before cleaning the system
WARNING
Overcurrent protection
CAUTION
For continued protection against fire hazard, use only fuses with the
required rated current, voltage, and specified type (normal blow ,
time delay). Do not use repaired fuses or short-circuited fuse
holders. Replace only with an identical fuse.
There are two resettable thermal bre a ke rs located on the power
strips. These are in the “hot” and “neutral” lines.
To prevent electrical shock, disconnect the system from mains before
cleaning. Use a dry (or slightly water-dampened) cloth to clean
external case parts. Do not atte mpt to clean internally.
If the power outlet strip breaker trips once, reset the breaker. If the
breaker trips twice, call a qualified/licensed electrician to service the
test system.

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

Introducing the Agilent 85225F Performance Modeling System1
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

Installation and User’s Guide19
1Introducing the Agilent 85225F Performance Modeling System
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
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.
*
to 50 GHz.
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 Semi conducto r Par a meter 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.
20Installation and User’s Guide
Introducing the Agilent 85225F Performance Modeling System1
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.
CAUTION
The Bias Networks
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 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.
