9.5.5.5 Calibration validation
This feature allows you to validate the active channel calibration against the expected
result from a stored characterization. It requires an R&S calibration unit.
●
Cal validation works with 2- and 4-port calibration units.
●
Currently, cal validation is limited to automatic calibrations. Furthermore, the same
calibration unit has to be used for calibration and validation.
Calibration validation provides an automated, single-click (basic) mode, and an
advanced mode for detailed validation and adjustment of limit tolerances, reporting,
and SCPI automation.
Basic mode
When "Cal Validation" is launched for the first time, it runs in basic mode. In this mode,
the R&S ZNL/ZNLE automatically detects the instrument ports connected to the cal
