If the measurement has been started as a single measurement (INITiate[:IMMediate]), the sensor goes into the idle state. However, if a continuous measurement is in progress (INITiate:CONTinuous ON), the trigger system of the sensor enters the waiting for trigger state.
Page 73: Triggering
® Remote control commands R&S NRPxxT(N) Controlling the measurement Manual operation: "Measurement" on page 46 9.5.2 Triggering In a basic continuous measurement, the measurement is started immediately after the command, see also Chapter 9.5.2.2, "Waiting for a trigger INITiate[:IMMediate] event", on page 73.
Page 74 ® Remote control commands R&S NRPxxT(N) Controlling the measurement 9.5.2.3 Trigger sources The possible trigger conditions and the execution of a trigger depend on the selected trigger mode and trigger source. If the signal power exceeds or falls below a reference level set by the trigger level, the measurement is started after the defined delay time.
Page 75: Controlling The Measurement Results
® Remote control commands R&S NRPxxT(N) Controlling the measurement The RF power between the slots is below the threshold defined by the trigger level and the trigger hysteresis. Therefore, the trigger hysteresis alone cannot prevent triggering at B or at C. Therefore, set the dropout time greater than the time elapsed between points D and B and between E and C, but smaller than the time elapsed between F and A.
Page 76: Interplay Of The Controlling Mechanisms
® Remote control commands R&S NRPxxT(N) Controlling the measurement Useful if you expect slow changes in the results, and you want to avoid outputting redundant data. Moving termination control Outputs intermediate values to facilitate early detection of changes in the measured quantity.
Page 77 ® Remote control commands R&S NRPxxT(N) Controlling the measurement Example: Repeating termination control Further settings for this example: ● [SENSe<Sensor>:]AVERage:TCONtrol REPeat The measurement is started by the trigger event. Due to the chopper phases, one measurement lasts twice the defined aperture time. As defined by the average count, after 4 measurements, the result is averaged and available.
Page 78 ® Remote control commands R&S NRPxxT(N) 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 84: Trigger:slope
® Remote control commands R&S NRPxxT(N) Controlling the measurement If enabled, select the output port for the trigger signal using TRIGger:SENDer:PORT. Typically, the trigger sender uses its internal trigger source. But you can also trigger the trigger sender externally, because the sensor has two external trigger connectors. If you trigger the trigger sender externally, use EXTernal1 as external trigger input port (trigger source) and EXTernal2 as trigger sender output port or vice versa.
