2.11 Error Code Interpretation Examples

This section presents three different examples of RF error code interpretation.

2.11.1 Example 1

ST_CDSP_RX_PLL_PHASE_LOCK self test gives "Fatal" result with error code:
This means that the total error code is
look a flowchart in section
for the code is "Hinku PLL is not locked".

2.11.2 Example 2

Some of the self-tests can return multiple errors at the same time.
For example: RF-BB interface (ST_CDSP_RF_BB_IF_TEST) self test gives "Fatal" result with
This means that the total error code without measurement values is
"0000 0000 0000

there are errors with two error codes:

2.11.3 Example 3

Supply test for Hinku and Vinku (ST_CDSP_RF_SUPPLY_TEST) is slightly different self test from others
because there are both Vinku and Hinku errors shown in the same error code (
explained in section
For example: ST_CDSP_RF_SUPPLY_TEST gives "Fatal" result with error code:
This error code means that there are probably no errors in Hinku RX ASIC supply voltages because the
main part of the error code for Hinku is
Anyway, there are many errors with Vinku TX ASIC supply voltages. The main part of the error code for
Vinku is 0x0B, 0xBC
