Receiver self test
Context
Receiver self test can be used to check the correct functionality of the receiver core. For the test, GPS software
configures internal test source to generate synthetic GPS-like data, processing it in the baseband and writing
the results into the channel processor memory. The test compares the data in the channel memory against
the expected value and reports a PASS/FAIL status.
Steps
1. Start Phoenix service software.
2. From the Testing menu, select GPS Control. This opens up
GPS Control
dialogue box and enables the GPS.
In the
Rx Control
window, go to the Simple Tests section, select Receiver Self Test and click Start. The
test returns a PASS/FAIL result.
Note: The Oscillator Test should not be run after the Receiver Self Test. This sequence of tests may
cause the Oscillator test to prolong and result in Phoenix timing out. If you are carrying out both of
these tests, run the Oscillator Test first, after which you can run the Receiver Self Test.
