4. Preparation of

Measurement Accessories

Agilent 4294A.

NOTE The 16334A must be directly connected to the four-terminal pair port of the Agilent

4294A. If another accessory such as a cable or adapter is inserted between the 16334A and

the four-terminal pair port of the Agilent 4294A, the correct adapter setup data cannot be

obtained and correct device measurement cannot be performed after the adapter setup.

Step 2. More than 30 minutes warm-up time is required after turning on the Agilent 4294A.

Step 3. Make the correct adapter selection for the 16334A in accordance with the “Adapter

Selection” on page 68.

Step 4. After performing Step 4 of the “Adapter Selection” on page 68, press the

SETUP key to

display the Adapter Setup Menu.

Step 5. Put the device contacts of the 16334A into the OPEN condition. Refer to the operation

manual of the 16334A for instructions on switching to the OPEN condition.

Step 6. Press the

PHASE COMP [-] key to start the phase compensation data measurement.

NOTE The traces on the LCD display do not change during the phase compensation data

measurement.

When the phase compensation data measurement is completed, the softkey label changes

to PHASE COMP [DONE].

Step 7. Connect a 100 W LOAD device to the 16334A.

Step 8. Press the

LOAD [-] key to start the load data measurement.

NOTE When the load data measurement is completed, the softkey label changes to

LOAD [DONE].

Step 9. Press the

done key to start calculating the adapter setup data from the measured phase

compensation and load data. The adapter setup data is automatically saved to the EEPROM

(nonvolatile memory) in the Agilent 4294A.

NOTE Press the cancel key to cancel the adapter setup process. If the adapter setup process is

canceled, the previously obtained data is saved as the available adapter setup data.

Adapter Setup Procedure for the 16451B

Perform the adapter setup for the 16451B Dielectric Test Fixture in accordance with the

following procedure:

NOTE Adapter setup should be performed at an ambient temperature as close as possible to the

temperature in which the device measurement will actually be made.

If the ambient temperature for your measurement is outside the range of ±5°C from the

adapter setup temperature, it is recommended that you perform adapter setup again at the

appropriate temperature.

It takes a few minutes to complete each setup data measurement.
