Ok so before I swapped the three units RX, RX Synt and SA from (what I thought was) my working unit I run the complete RF_Diags and I was surprised that I now got ONE failure on the test and it was the 900 MHz, 114.3 MHz IF test that measures -2.306 dBm while the lower limit is -2 dBm.... Dough.... this unit used to work well without errors on the RF_Diag test.
Anyway, I swapped the three units RX, RX Synt and SA into the non-working unit and now I get only ONE error on the failing unit instead of 6 failures and now the only fail is in the RX assembly test and it is on the Down Converter test but now for the 500M MHz, 114.3 MHz if showing -3.275 dBm compared to the fail on the working unit where it fails on the 900 MHz frequency.
Am i correct in my conclusion now that it is a problem somewhere in the Down Converter path since I ONLY get one error in RF_Diag running the full RF_Diag tests and no errors in the SA tests? (The SA module in the failing unit is still having problems since if I put back that SA module I get more errors.)
I just realised that I forgot the results of running the RF_Diags WITHOUT the SA module installed. Will do that tonight and report back.
So instead of looking for only a SA module to test with (before attempting a repair of the SA module) I need to find a working RX module to test with.?
I am a little bit confused of the part number for the Receiver Module...
I see?08920-61828 in the Assembly Level Repair document but I have also seen?
08920-61028
08920-61102
Will all those part numbers work or are those two other ones different in some way?
