Preparation of Measurement Accessories
Adapter Setting
During each data measurement, the message “WAIT--MEASURING ADJUSTMENT
KIT” is displayed in the instrument state area in the LCD's upper-left side.
Step 1. Make sure that the 16451B is correctly connected to the four-terminal pair port of the
Agilent 4294A.
NOTE The 16451B Dielectric Test Fixture 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 16451B 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 16451B in accordance with “Adapter Selection”
on page 68.
Step 4. After performing Step 4 of “Adapter Selection” on page 68, press the
SETUP key to
display the Adapter Setup Menu.
Step 5. Put the device contacts of the 16451B into the OPEN condition. Refer to the operation
manual of the 16451B 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 PHASECOMP[DONE].
Step 7. Press
done key to start calculating the adapter setup data from the measured 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 42942A
Perform the adapter setup for the 42942A Terminal Adapter in accordance with the
following procedure (operation manual of the 42942A also describes the adapter setup
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.
During each data measurement, the message “WAIT--MEASURING ADJUSTMENT
