In the upper part of the "Cal Unit" screen, the R&S
ZNL/ZNLE shows the calibration
sweep diagrams for the currently measured S-parameter. The lower part visualizes the
active port assignment and the measurement progress.
Calibration Sweep Diagrams
During the calibration sweep, each diagram contains a single S-parameter trace and a
typical result trace for the measured calibration standard.
The purpose of the typical result traces "Trc1"" and "Trc2" is to avoid connection errors:
If the correct standard type is measured, and everything is properly connected, then
the measured trace is expected to be similar to the typical trace.
The S-Parameter traces are labeled P[
j
_
i
]_<standard type> S
ij
, where
j
indicates the
input (test) port and
i
indicates the output port, e.g. P[1_2]_Unknown_Through S21.
Start Cal Sweep / Abort Sweep
Starts the calibration sweep for the related port assignment or aborts it.
Detect Ports & Start Cal
Performs the "Detect Port Assignment" and "Start Cal Sweep" functions, one after the
other.
