[time-nuts] HP-53132A Faded and flickering display

[Azelio Boriani]

You will be using the counter much on the GPIB than looking to the display,
so try to keep the unit untouched. Better to use it and think about another
one, now that you have one, you are not in a hurry so you can select a
better one. You can also hunt for an SR620 or a Wavecrest... 25pS (or less)
instead of 150pS is better. Isn't it?
