During remote operation of the Spectrum Monitor you should configure the trigger arm to single, see SETup:SMONitor .
The Spectrum Monitor may not return a result when the trigger arm is set to a setting other than single. When trigger arm is continuous, the Spectrum Monitor rearms itself and starts another measurement cycle. The fetch query may not be synchronized to the measurement cycle during remote operation (see Measurement States ).
The results returned will be unreliable if Trigger Source Immediate is used for burst modulated signals. Burst modulated signals should be measured with Trigger Source set to RF Rise or Auto. For RF Rise triggering to work correctly, the signal should be no less than 20 dB below the reference and greater than -20 dBm.
