This section describes the calibration procedures to follow when the four-terminal pair port of the E4990A is extended with a 2-meter-long four-terminal pair configuration and the device is connected to the cable’s end with a minimal connection.
This calibration procedure is applied to the following connections:
The 16048H (2-m Cable) is connected to the E4990A and the device is connected to the cable’s end with a test fixture.
The 16048H (2-m Cable) is connected to the E4990A and 16452A (Liquid Test Fixture) is connected to the end of the cable.
Make sure that the adapter selection is set to 4TP 2m. Perform Adapter Setup if it is not done yet.
Perform the fixture compensation in accordance with Fixture Compensation.
When the measurement port is extended by 2 meter with the four-terminal pair configuration, neither user calibration nor port extension compensation is required for measurement (they cannot be performed).
