[time-nuts] HP 53310A

[time-nuts at quackers.net]

Arg, Chan A on mine just died. If you don't know what these are, they 
are a real gem, far better than HP ever marketed them to be. Geller Labs 
did a writeup back in 2019, but my link doesn't work anymore. 14 digits 
of frequency precision possible, sub-nanosecond rise-time measurements, 
etc. without all the horrible analog tweaking the classic HP 5370 
required. Trivial calibration procedure.

Anyway, two actual comments - anyone know of common failure modes? Mine 
is clearly on the input channel analog side, the led for signal doesn't 
blink. Fortunately, I have a spare unit, but I'd like to fix this one. I 
do have the CLIP for it.

Second comment, wow, prices have gone insane on EPray! Why? I have 3 of 
these, 2 with the 2.5Ghz mixer and one without. I got all of them for a 
couple of hundred bucks some few years ago.
