Cable Rider ZPH

User Manual 1321.0950.02 ─ 07
This automatic routine makes sure that the signal power level does not overload the
R&S Cable Rider ZPH or limits the dynamic range by too small an S/N ratio.
To determine the best reference level, the R&S Cable Rider ZPH aborts current mea-
surements and performs a series of test sweeps. After it has finished the test, it contin-
ues with the actual measurement.
This command is an event and therefore has no *RST value and no query.
The numeric suffix at CALCulate is irrelevant for this command. The numeric suffix at
MARKer selects the marker.
