Silly question perhaps but it does have a frequency standard fitted and it
is switched to internal?
Apologies if this has been discussed before, head a bit sieve like these
days, but it's not unusual for some variants to be supplied without the
internal standard on the assumption an external reference will be used.
If the answer is "yes" then I would suggest using a 'scope, plus frequency
counter if possible, to track internally against the diagrams in the manual
to see just what signals are being produced and whether or not they're as
expected.
All the necessary information for signal tracing is in the manual and it
even suggests that most basic functional checks can be made with a DMM and
20MHz frequency counter.
