Unit / Info
Returns
• "1", if an Auto- modulation
frequency was detected on the
incoming signal.
• "0" otherwise
Returns
• "0", if the incoming signal is not
modulated or Auto- modulation
frequency is detected.
• the modulation frequency [Hz]
otherwise
Response type: <NR1>
Fetches the values measured by the
device depending on its mode:
POW: input power fetched
Resonse type: <NR3,NR3,NR3>
Response unit:
• Absolute display
(:POW:REF:STAT 0)
- in dBm for :POW:DISP:UNIT LOG
- in W for :POW:DISP:UNIT LIN
• Relative display
(:POW:REF:STAT 1) in dB
RET_LOSS: Return loss fetched
Response unit: dB
+9.91E37 overflow
9.91E37 underflow
The number of values fetched (1...3)
depends on the number of
wavelengths measured on the
incoming signal.
