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 3.5-mm connector
of the 42941A Impedance Probe. Enter electrical
length or delay time for the extension.
Compensation performed at the device contacts of the
test fixture using OPEN, SHORT, LOAD.
Fixed points or user points determined by sweep
setups
23 ± 5°C
Beyond 23 ± 5°C, the measurement accuracy
decreases to half the value described.
Within ± 5°C from the adapter setup temperature.
Measurement accuracy applies when the adapter
setup is performed at 23 ± 5°C. When the adapter
setup is performed beyond 23 ± 5°C, the
measurement accuracy decreases to half the value
described.
