Self test troubleshooting
Troubleshooting with RF Self tests
Context
RF ASIC contains test structures that can be used to detect certain RF related errors. In order to use these self
tests the most efficient way, it is very important that the tests are performed in a certain order, or at least
that the error data is analyzed in this order. The tests are designed so that by going through them in this
order it is easy to find the problem component without any redundant checks. The flowcharts presented in
this document are based on that idea.
The testing order recommended and used in this troubleshooting guide is the following:
1 ST_CDSP_RF_BB_IF test (ID hex. 56)
•
Tests the functionality of the BB/Linko serial interface & reset lines.
•
If this test fails, it means that there is a problem in programming of the N7512 and all of the following
tests cannot give correct data.
2 ST_CDSP_RF_SUPPLY_TEST (ID hex. 53)
•
Tests the functionality of N7512 bias block, regulators, reference voltage line and supply connections,
as well as almost all Aura (N7509) regulator voltages..
•
If this test fails, all other N7512 tests can/will fail.
3 ST_CDSP_DIGI_RXTX_IF_TEST (ID hex. 7D)
•
Test checks that the digital RX and TX lines between BB and N7512 are properly connected.
4 ST_CDSP_STROBE_TEST (ID hex. 7C)
•
Tests the functionality of the RFStrobe signal..
5 ST_CDSP_PA_ID_PIN_TEST (ID hex. 7F)
•
The purpose of this test is to identify the PAs of the different vendors.
•
Tests also the functionality of the temperature sensor V7502.
6 ST_CDSP_TX_WCDMA_POWER_TEST (ID hex. 4B)
•
Tests the basic functionality of the WCDMA transmitter.
To get the best out of these instructions you need to be have the valid schematics at hand.
