If a measurement is completed, the sensor does not return to the idle state but enters the waiting for trigger state again. Ends the continuous measurement mode, and sets the sensor to the idle state.

Remote control commands R&S ® NRPxE Controlling the measurement 8.5.4 Interplay of the controlling mechanisms In the following examples, continuous measurement scenarios are used. But these scenarios also apply to single measurements. The only difference is that a single mea- surement is not repeated.
Page 54 Remote control commands R&S ® NRPxE Controlling the measurement Example: Moving termination control Further settings for this example: ● [SENSe<Sensor>:]AVERage:TCONtrol MOVing ● TRIGger:COUNt Every measurement is started by a trigger event. Due to the chopper phases, one measurement lasts twice the defined aperture time. During each measurement, the trigger synchronization is high (TRIGger:SYNC:STATe ON).
Page 55 Remote control commands R&S ® NRPxE Controlling the measurement Example: Average count = 1 [SENSe<Sensor>:]AVERage:COUNt For average count 1, the setting of the termination control has no impact. In both cases, the measurement runs for the duration of one aperture time. Then, settled data is available, and the sensor returns to the idle state.
