tune action stopped :MSD Fault 2 : RFPA Difficulty ?

Hi

Did you check PFTBA level.

Did you check column length.

May be pftba is low or column length coming out from transferline in MS is more.

How old is Electron multiplier horn..

Check this link for column and make sure it is with correct lenth and not broken..

dear ISH

checking  column length was 1 mm after tip.

checking PFTBA level. was ok

 Electron multiplier horn. is 3 years old and give emv 1600 

Okay..

Can you share last tuning report..

You are sure that no one did any dope frequency test..

dope means what?

Means Quad frequency adjustment.

Check again all wires are connected properly otherwise it looks electronics problem to check onsite..

i sent a pic to tune file
