4.7.6.2 Sensor test with applied RF
Testing the sensor with the RF reference signal requires option R&S NRP2-B1, Sensor
Check Source.
► Open the "Sensortest" dialog box in the "System"
→
"Test..." menu and select the sec-
ond page.

This page of the "Sensortest" dialog box provides testing the sensors with the reference
signal supplied by the R&S
NRP2-B1 test generator option.
In the case of sensors with a lead-in attenuator (pad) (R&S NRP-Z22, R&S NRP-Z23 and
R&S NRP-Z24), the test measurement can be made with or without an attenuator. Since
the power sensors of the R&S NRP-Z series are absolutely calibrated, a regular calibra-
tion measurement after switching on the instrument is not necessary and also not plan-
ned.
The outcome of the tests is not considered during subsequent measurements.
Test at Power Ref
Starts a test measurement for a sensor. The sensor must be connected to the sensor
check source.
If an attenuator is present, it must first be removed.
This way, you can test all measurement paths of R&S NRP-Zxx multi-path sensors.
Additionally you can test an attenuator in the "... with pad" setting.
During test procedure, the instrument indicates that the test is currently running.

After completion, the instrument shows a results message.
