6.12.5 How to Calibrate the Power Level with an R&S NRP Power Sensor
Using a R&S NRP power sensor and the user correction function of the instrument,
you can compensate external frequency responses. The R&S SMBV100B 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 SMBV100B
1. Connect the power sensor.
See Chapter 6.12.4.1, "Connecting R&S NRP Power Sensors to the
R&S SMBV100B", on page 393.
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 6.12.4.2, "NRP Sensor Mapping", on page 394
5. Close the dialog.
To configure and calibrate the R&S NRP in the R&S SMBV100B
Provided the power sensor is connected to the R&S SMBV100B 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, turn off the RF output signal.
2. Select "RF" > "RF Measurement" > "NRP Power Viewer".
3. If the R&S SMBV100B has detected several connected power sensors, select the
tab of the sensor you want to use.
4. Select "Zero" to start zeroing of the sensor.
Note: Always turn the RF power off or disconnect the sensor from RF before zero-
ing, since the function calibrates the power sensor at zero signal power.
The zeroing process takes a few seconds, depending on the power sensor type.
5. Configure additional parameters for the selected sensor as required.
6. Select "State > On".
