Calibration
D. Calibration When an Exclusive Fixture is Connected to the 42942A
See “Adapter Setting” on page 67 for adapter selection.
Step 2. When performing calibration for the 7-mm port of the 42942A with a user-defined
calibration kit, be sure to use the proper calibration kit. Refer to “User Calibration” on
page 147 for the user calibration procedure.
User calibration is not required if you do not use a user-defined calibration kit.
Step 3. Connect a test fixture to the 7-mm port of the 42942A Terminal Adapter. See the operation
manual of each test fixture for the appropriate connection setup.
Step 4. Perform the fixture compensation at the device contacts (electrodes) of the fixture. See
“Fixture Compensation” on page 151 for the fixture compensation procedure.
NOTE When an exclusive test fixture is connected to the 7-mm port of a 42942A that is also
connected to the four-terminal pair port of the Agilent 4294A, port extension compensation
is not required.
