example: read1:pow?
->
+1.33555600E-006<END>
affects: All power meters and return loss modules and attenuator with power control
dual sensors: Can only be sent to master channel, slave channel is also triggered.
To read a simultaneous result from the slave channel, send
:FETCh[n][:CHANnel[m]][:SCAlar]:POWer[:DC]?
on page 88 directly after this command.
command: :READ[ n ][:CHANnel[ m ]][:SCALar]:RETurnloss?
syntax: :READ[ n ]:[CHANnel[ m ]][:SCALar]:RETurnloss?
description: 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 91), this command is identical to
:FETCh[n][:CHANnel[m]][:SCAlar]:RETurnloss?
on page 88.
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 89) and then reading the power meter value.
The return loss module must be running for this command to be effective.
parameters: none
response: The current power meter reading as a float value in dB.
example: read1:ret?
->
+1.33555600E-000<END>
affects: All return loss modules
command: :READ[ n ][:CHANnel[ m ]][:SCALar]:MONitor?
syntax: :READ[ n ]:[CHANnel[ m ]][:SCALar]:MONitor?
description: Reads the power value at the monitor diode (forward path). It provides its own software triggering and does not need a
triggering command.
If the software trigger system operates continuously (see Chapter , “:INITiate[n]:[CHANnel[m]]:CONTinuous?,” on page 91),
this command is identical to
:FETCh[n][:CHANnel[m]][:SCAlar]:MONitor?
on page 89.
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 89) and then reading the power meter value.
The return loss module must be running for this command to be effective.
parameters: none
response: The current power meter reading as a float value in W or dBm
example: read1:mon?
->
+1.33555600E-000<END>
affects: All return loss modules
