Measurement details

No measurement yet.

Calibrate at the cable end

Use ideal OPEN, SHORT and 50 Ω LOAD standards.
Transmission calibration

Connect a THROUGH between both ports. For ISOLATION, terminate both ports with 50 Ω loads.

Calibration standard models

Use the values supplied with your standards. Zero gives ideal OPEN and SHORT.
