Page 48: Controlling The Measurement Results
® Remote control commands R&S NRP18S-xx Controlling the measurement 1 = Dropout time 2 = Trigger hysteresis 3 = Trigger level 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.
Page 49: Interplay Of The Controlling Mechanisms
® Remote control commands R&S NRP18S-xx Controlling the measurement Repeating termination control Outputs a measurement result when the entire measurement has been completed. This means that the number of measurement cycle repetitions is equal to the set aver- age count. If the average count is large, the measurement time can be very long. Useful if you expect slow changes in the results, and you want to avoid outputting redundant data.
Page 50 ® Remote control commands R&S NRP18S-xx 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 51 ® Remote control commands R&S NRP18S-xx 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 52 ® Remote control commands R&S NRP18S-xx 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 power sensor returns to the idle state.

® Remote control commands R&S NRP18S-xx Configuring basic measurement parameters Sets the duty cycle for measuring pulse-modulated signals. The duty cycle defines the percentage of one period during which the signal is active.

Page 80: S-Parameter Correction
® Remote control commands R&S NRP18S-xx Configuring basic measurement parameters 8.8.4.3 S-parameter correction S-parameter correction compensates for the losses and reflections introduced by a component — such as an attenuator, directional coupler, or matching pad — that is attached to a power sensor. Using S-parameters instead of a fixed offset increases measurement accuracy by accounting for the interaction between the power sensor and the component.
