Before I dive into this beast, I thought I'd better consult you folks
first...
I have a Tek 7704A, working and mostly looking good.
One thing I notice though is that the readout characters shift a bit
to the right while the beam is sweeping from left to right. When the
beam is blanked (and goes back to the left) the readout characters pop
back. Readout Mode switch is in 'Free run' position, by the way.
It is only a minor shift, say 1/20th of a graticule unit, but annoying
nevertheless, especially at low sweeptimes when using a 7L12.
Offhand, I'd say there is a power supply that isn't stable. Or is this
normal behaviour? Nah....
I'd be grateful for any pointers before I whip out the schematics and
DVM...
Bart.
There may be a 'NOSPAM.' (mind the dot!) in front of my E-mail address.
It is there to fool machines, not people. Please remove it when you want to reply to me personally.
