Calibration
Calibration
User calibration
Port extension
Calibration performed with user-defined calibration kit (OPEN, SHORT, LOAD)
Compensation performed when the measurement terminal is expanded from the 7-mm connector of the
42942A Terminal Adapter or the test port of the 42941A Impedance Probe. Enter electrical length or delay time
for the extension.
Fixture compensation
Calibration points
Compensation performed at the device contacts of the test fixture using OPEN, SHORT, LOAD.
Fixed points, or User points determined by sweep setups
