command: :FETCh[n][:CHANnel[m]][:SCAlar]:MONitor?
syntax: :FETCh[n]:[CHANnel[m]][:SCAlar]:MONitor?
description: Reads current powe r value at a r eturn loss mod ule’s monitor diod e (forward pa th). It does
not provide its own triggering and so must be used with either continu ous software trigger-
ing (see “:INITiate[n]:[CHANnel[m]]:CONTinuous?” on page8 9) or a directly preceding im-
mediate software trigger (see “:INITiate[n]:[CHANnel[m]][:IMMediate]” on page88).
It returns the monitor value the previous software trigge r measured. Any subsequent FETCh
command will return the same value, if there is no subsequent software trigger.
parameters: none
response: The current value as a float value in W or dBm.
example: fetc1:mon ? → +6.73370400E-00<END>
affects: All return loss modules
command: :INITiate[n]:[CHANnel[m]][:IMMediate]
syntax: :INITiate[n]:[CHANnel[m]][:IMMediate]
description: Initiates the software trigger system and completes one full trigger cycle, that is, one mea-
surement is made.
parameters: none
response: none
example: init
affects: All power meters, return loss modules.
dual sensors: Can only be sent to master channel, sl ave channel is also affected .
command: :INITiate[n]:[CHANnel[m]]:CONTinuous
syntax: :INITiate[n]:[CHANnel[m]]:CONTinu ous<wsp><boolean>
description: Sets the softwa re trigger system to continuous measurement m ode.
parameters: A boolean value: 0 or OFF: do not measure continuously
1 or ON: measure continuously
response: none
example: init2:cont 1
affects: All po wer meters, return loss modules.
dual sensors: Can on ly be sent to master channel , slave channel is also affected.
