Step 3: Cal Unit
During the calibration phase the R&S
ZNB/ZNBT displays a "Cal Unit" screen that
guides the user through the actual correction data acquisition.
In each calibration step
●
the calibration unit has to be (re-)connected according to the depicted port assign-
ment; auto-detection is possible
●
the related test ports are calibrated with the "Calibration Type" selected in
●
a subsweep is performed for every required test port (pair), for every possible path
