In the upper part of the "Cal Unit" screen, the R&S ZNC 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
Each diagram presents an S-parameter trace and a typical result trace for the measured
standard type.
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]_Through S21.
Remote command:
n/a
Start Cal Sweep / Abort Sweep
Starts the calibration sweep for the related port assignment or aborts it
Detect Port Assignment
Starts a procedure by which the R&S ZNC (with a little help from the attached calibration
unit) auto-detects the connected ports. The automatic assignment replaces the config-
ured one.
In case auto-detection fails
●
an error report is shown as a warning dialog
●
the undetected port connections are overlayed by warning signs
