:FETCh[n][:CHANnel[m]][:SCAlar]:MONitor?

:FETCh[n]:[CHANnel[m]][:SCAlar]:MONitor?

Reads current power value at a return loss module’s monitor diode (forward path). It does not provide its own triggering and so must be used with either continuous software trigger- ing (see “:INITiate[n]:[CHANnel[m]]:CONTinuous?” on page 89) or a directly preceding im- mediate software trigger (see “:INITiate[n]:[CHANnel[m]][:IMMediate]” on page 88).

It returns the monitor value the previous software trigger measured. Any subsequent FETCh command will return the same value, if there is no subsequent software trigger.

none

The current value as a float value in W or dBm. fetc1:mon? → +6.73370400E-00<END>

All return loss modules
