Hello Nuts,
Looking for some help with an FEI FE-5650A. This is one of the units that
is surplus from the telecom industry with the Option 02 serial interface.
Unit was working fine - locked, and was able to control the frequency by
issuing commands to the serial port. Then something funny happened,
oscillator went unlocked and cycling the power does not help. I have
dumped what data I can (see attachments) and the software inside the 5650
appears to be corrupted.
Attached are two files, one from a good 5650A and one from the bad 5650A.
It appears that several of the data areas have been over-written with the
9-byte sequence 2D 09 00 24 00 00 00 00 24. This would be the response to
the 2D query command, except the data in the frequency register was
probably not 00 00 00 00 at the time of failure and 24 looks like the
checksum for the header and is not the checksum for 00 00 00 00 (which
would be 00).
Is there an ex-FEI engineer out there in time-nuts land?
Has anyone else seen such behavour?
Is there any known way to reset the software for the 5650?
Has anyone dumped the 5650 microcode (I vaguely recall one of the rubidiums
having been dumped)?
I took the processor board from a good 5650 and put it on the bad unit and
it locks fine. My next step is to write a control word to the bad unit
then read it back and see if it shows up in the memory dump, to see if the
memory over-write is dynamic (the program has been premanently changed) or
if it looks like it happened only once.
Any information would be helpful, or suggestions on debug.
Thanks in advance.
