:INITiate[n]:[CHANnel[m]]:CONTinuous
:INITiate[n]:[CHANnel[m]]:CONTinuous<wsp><boolean>
Sets the software trigger system to continuous measurement mode.
A boolean value: 0 or OFF: do not measure continuously
1 or ON: measure continuously
none
init2:cont 1
All power meters and return loss modules
Can only be sent to master channel, slave channel is also affected.
:INITiate[n]:[CHANnel[m]]:CONTinuous?
:INITiate[n]:[CHANnel[m]]:CONTinuous?
Queries whether the software trigger system operates continuously or not
none
A boolean value: 0 or OFF: measurement is not continuous
1 or ON: measurement is continuous
init2:cont? → 1<END>
All power meters and return loss modules
Can only be sent to master channel, slave channel parameters are identical.
:READ[n][:CHANnel[m]][:SCALar]:POWer[:DC]?
:READ[n]:[CHANnel[m]][:SCALar]:POWer[:DC]?
Reads the current power meter 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]:POWer[:DC]?" 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 power meter must be running for this command to be effective.
none
The current power meter reading as a float value in dBm, W or dB.
If the reference state is absolute, units are dBm or W.
If the reference state is relative, units are dB.
read1:pow? → +1.33555600E-006<END>
All power meters and return loss modules
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 70 directly after this
command.
