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 33

1 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

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.

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.

WARNING

Failure to comply with the following precautionary safety ins truct ions 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 thes e step s to ensur e your saf et y.

To ensure your safety while using the system

Step Action Notes
1 Never operat e the sy st em

without a safety earth
ground.

2 Never attempt to service

a Ensure that a safety earth ground is

connected between the system power
distribution unit and the line power source.

b If it is likely that the safety earth ground

has been impaired, the system must be
rendered inoperative and secured against
unintended operation .

a Contact Agilent Technologies if service is

required.

• Capacitors within the system

components can remain charged even
after the system is disconnect ed from
its line power source.

• The system may only be serviced,

adjusted, maintained, or repaired by
qualified personnel.

3 Open the DC subsystem

interlock connection
whenever possible.

a Close the DC subsystem INTLK (Interlock)

connection only when voltages greater

• Alternately, an externally installed

switch or circuit breaker (readily
identifiable and easily reached by the
operator) may be used as a
disconnection device.

2 Installing the System

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.

WARNING

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.

NOTE

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 CIRCUI T COMMON and CHASSIS

GROUND terminals.

2 Connect the external ground to the CIRCUIT COMMON of the DC subsystem.

3 Verifying System Functionality

Understanding the S ystem 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.

Required Tools

• Agilent 85225F performance modeling system

• A system controller

• Agilent 85190A IC- CAP software

• Test port cables

• This removes th e instrument from GPIB

control, activates the front panel
interface, and returns the instrument to
its factory preset condition.

• Actions c through h prepare the

network analyzer for a full range 2-port
calibration using the same instrument
state settings used by the IC-CAP
functional verification test macro.

• For detailed instructions, see

“Performing a Coaxial System
Measurement Calibration"on

page115.

• This begins a modified full 2-port

calibration.

• When prompted to connect a standard

to either Port 1 or Port 2, connect the
standard to the semi-rigid cable
attached to the Por t 1 or Port 2 bias
network.

• An isolation calibration is not needed

for this measurement.

f As IC-CAP performs an optimization,

observe the simulated data trace converge
with the measured data trace.

b In the IC-CAP/Status window, observe the

final DC/RF values parameter and the Final
RMS error.

• This opens the Atten model window’s

Macros tab folder.

• This starts a sequence of prompts and

responses.

• IC-CAP performs measurements of the

attenuator’s DC and RF parameters.

• When complete, IC-CAP displays plots

of the forward and reverse DC voltage
transfer through the attenuator. The
solid line is the measured data, the
dashed line is the simulated data.

• IC-CAP be gins the optimization process

using default simulated data. These
values are optimized to converge with
the measured data.

• When the S-parameter measurement is

complete, IC-CA P displays plots of the
S12/21, 20×log
magnitude, and S21 phase.

• IC-CAP also lists the attenuato r’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. Thi s v alue
(typically in the femtosecond to
nanosecond range) de pends on the
length of the attenua tor.

• The S21 magnitude and the S12/S21

plots, of less significance, are included
for your interest.

• The S21 simu lated 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.
