If the S-parameter device and/or the offset correction are disabled, the trigger thresh- old and its input limits are adjusted as necessary.
Page 85: Trigger:slope
® Remote control commands R&S NRPxxA(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.

The sampling values are subjected to weighting (raised-von-Hann win- dow), which corresponds to video filtering. If you deactivate the smoothing filter, 300 to 3000 periods are required to obtain the same effect.

Page 96: Offset Corrections
® Remote control commands R&S NRPxxA(N) Configuring basic measurement parameters 9.7.3.2 Offset corrections The offset accounts for external losses by adding a fixed level offset in dB. The attenuation of an attenuator located ahead of the sensor (or the coupling attenua- tion of a directional coupler) is considered with a positive offset.
Page 97 ® Remote control commands R&S NRPxxA(N) Configuring basic measurement parameters All NRP sensors allow compensating for the influence of any two-port device- between the signal source and the sensor input. As a result, the firmware can calculate the power that the signal source actually delivers. Examples of such two-port devices- include attenuators, matching pads, minimum-loss pads and waveguide adapters.
