[time-nuts] HP 5345A Noise Floor

[Bob kb8tq]

Hi

According to page 1-3 in https://bama.edebris.com/download/hp/5345a/5345a_6.pdf <https://bama.edebris.com/download/hp/5345a/5345a_6.pdf>

The 5345 is a 2 ns counter. Roughly speaking, that normally gets you around  2x10^-9
at 1 second.

That would suggest there is something a bit off in your setup.
