I have no idea what happened, and no idea
how it was fixed. I am just grateful that my spectrum
analyzer is alive again. I felt "blind" without it.
It is both a massive relief and deeply worrying when this sort of thing
happens. My 7L5 has got a similar quirk - the spectrum will shoot off
800kHz up the display from the reference dot - and then will come back and
jitter around, settle down for a while then - back up to 800kHz.
OK - an intermittent fault I hear you say - probably in the PLL. Heh - so
far it has defied attempts to find it; seems to obey some qunatum mechanical
behaviour: as soon as you offer it violence by trying to fix it, it settles
down for a few hours. Until I really want to use it again, that is.
But good luck with the 2753P - at least like my 7L5, it isn't *really* bust,
just being an awkward SOB.
