Perform the following calibration when a probe adapter supplied with the 42941A Impedance Probe is directly connected to the test port of the 42941A, which is connected to the four-terminal pair port of the E4990A, and a device is connected to the probe adapter.
This calibration procedure is applied when the following probe adapters are connected to the test port of the 42941A (see the operation manual of the 42941A for details of probe adapters):
Pin Probe (with ground electrode or ground lead)
BNC(m) Adapter
BNC(m) Adapter with alligator clip leads
Make sure that the adapter selection is set to PROBE 42941A. Perform Adapter Setup if it is not done yet.
When performing calibration at the test port of the 42941A with a user-defined calibration kit, perform user calibration with the proper calibration kit. Refer to User Calibration for the user calibration procedure. User calibration is not required when you do not use a user-defined calibration kit.
Connect a probe adapter to the test port of the 42941A Impedance Probe. See the operation manual of the 42941A for the appropriate connection setup.
Perform the fixture compensation at the device contacts (electrodes) of the probe adapter. See Fixture Compensation for the fixture compensation procedure.
When a probe adapter is connected to the test port of a 42941A that is also connected to the four-terminal pair port of the E4990A, port extension compensation is not required.
