Meas Off (Spectrum Analyzer) Measurement
Mode
External Sets an external input signal as the trigger source. A new sweep/measurement
will start when the external trigger condition is met by the signal applied at the External
Trigger Input.
RF Burst (Wideband) Sets the RF Burst as the trigger source. A new sweep/measurement
will start when an RF burst envelope signal is identified from the signal input to the RF
INPUT connector.
Trigger Level Sets the level where a trigger occurs. When the trigger signal level crosses
the specified level (for the selected slope), the trigger occurs. This level is displayed with a
horizontal line only if Video is the selected trigger source.
For RF Burst, sets the absolute trigger level for the RF burst envelope.
Example TRIG:SOUR EXT This selects the external trigger input.
