Testing Receiver Sensitivity

You can carry out a basic test of the receiver's
equipment. The test only works if the receiver has a 50 ohm load and is not
receiving any RF signal. You can set this up by connecting up a test set and
switching its RF off.
1. Disconnect the antenna and connect a 50 ohm load.
2. Select Diagnose > Reciter > Receiver.
3. If necessary, alter the receiver's frequency and channel spacing in the Set
receiver test frequency area.
4. Click Test Rx Sensitivity. The Result box indicates whether the receiver
passed or failed the test. If the receiver was receiving any RF, the test result
will be 'fail.'
You can measure the strength of RF signal that the base station receives across
a band of frequencies. A bar graph displays the results.
This test lets you see what signals are out there; it does not determine the
receiver's sensitivity.
