7.8.5 How to Calibrate the Power Level with an R&S NRP Power Sensor
Using a R&S NRP and the user correction function of the instrument, you can achieve
a stable output level of high accuracy over a specified frequency range. The
R&S SMW utilizes the readings of the power sensor and creates a correction value
table for controlling the output level during operation.
To connect the R&S NRP to the R&S SMW
1. Connect the power sensor.
See Chapter 7.8.4.1, "Connecting R&S NRP Power Sensors to the R&S SMW",
on page 540.
2. Select "RF" > "RF Measurement" > "NRP Sensor Mapping".
3. If the sensor is not detected automatically, select "Scan > Start".
The instrument scans the network and the USB connections for connected sensors
and lists all detected R&S NRP sensors in the mapping table.
4. In the "Mapping" column, assign the sensor to a sensor channel (see Chap-
ter 7.8.4.2, "NRP Sensor Mapping", on page 541
5. Close the dialog.
To configure and calibrate the R&S NRP in the R&S SMW
Provided the power sensor is connected to the R&S SMW and is assigned to a sensor
channel, we recommend that you calibrate and configure the power sensor in the "NRP
Power Viewer" dialog.
1. In the block diagram > RF A, turn off the RF output signal.
2. Select "RF" > "RF Measurement" > "NRP Power Viewer".
