I checked both CMU voltages and the are the same.
The CMU-B68 are not interchanged !!!!
I gues that both CMU-B68 are irrearable, the reason for the bad caps will be probably too high voltage on some way generated into the CMU-B68.
This will demaged some other components on that PCB too, without a decent schematic it will be inpossible to find out wat is wrong.
But as I said before I can use the CMU200 without CMU-B68.
I tested the spectum analyser and RF generator and both are working.
But the " Internal RF Loop Selftest " is not OK : ERROR
I did connect RF2 ( as output ) to RF1 (as input)
Level Tx -10dB give me -25dB on the analyser screen. A loss from -15 db
??
I can solve this by putting RF 1 to +15.0dB but that is not the right way.
That is my next problem now
