rf signal generator pll

[sperelat]

What I;m doing now is doing test of a rf signal generator.




When I turned it on, it showed Uncal warning and generated no rf
signal.


Meaning of error code was that PLL is unlocked.


I'm ,however, newcomer to RF generator world.

What does "PLL unlocked " means for RF signal generator.


The model I'm doing test is


fluek 6060 B

PLL = Phase Lock Loop

Check here for service manual: http://www.fullnet.com/~tomg/manuals.htm

Also check e-bay.

If error is related to the phase loop, it can be in the forward gain stage
or anything related to the feed-back loop. Oftentimes, this happens when
someone tries to feed power into the RF OUTPUT and damages it. The forward
gain-block is the next most common fault.

Good luck,
