:READ[n][:CHANnel[m]][:SCALar]:RETurnloss?
:READ[n]:[CHANnel[m]][:SCALar]:RETurnloss?
Reads the current return loss value. It provides its own software triggering and does not
need a triggering command.
If the software trigger system operates continuously (see
":INITiate[n]:[CHANnel[m]]:CONTinuous?" on page 71), this command is identical to
":FETCh[n][:CHANnel[m]][:SCAlar]:RETurnloss?" on page 70.
If the software trigger system does not operate continuously, this command is identical to
generating a software trigger (":INITiate[n]:[CHANnel[m]][:IMMediate]" on page 70)
and then reading the power meter value.
The return loss module must be running for this command to be effective.
none
The current power meter reading as a float value in dB.

:SENSe[n]:[CHANnel[m]]:CORRection[:LOSS][:INPut][:MAGNitude]
:SENSe[n]:[CHANnel[m]]:CORRection[:LOSS][:INPUT][:MAGNitude]<wsp>
<value>[DB|MDB]
Enters a calibration value for a module.
The calibration factor as a float value
If no unit type is specified, decibels (dB) is implied.

Master and slave channels are independent.
:SENSe[n]:[CHANnel[m]]:CORRection[:LOSS][:INPut][:MAGNitude]?
:SENSe[n]:[CHANnel[m]]:CORRection[:LOSS][:INPUT][:MAGNitude]?
Returns the calibration factor for a module.
none
The calibration factor as a float value. Units are in dB, although no units are returned in
the response message.
