Hi Said,
My hp53310 shows the same artifacts if the input frequency is nearly
the reference frequency. If I use the reference as input frequency
the noise is lower. When I adjust the time/div to more than 2 times
the frame flyback time, I can see a disturbance at the fylback
interval with

We had a discussion about this, and some other folks did see it also.
Sometime around June last year or so, I need to dig up my measurements.

Nor have I. I have several 53131's and a 53132. The 53132 is always
logging data against one of my Cs's and an M12T.

Can you refresh me on the topic? I didn't see any

Hello Said,
I have seen something similar with my 53132A. I was checking
on the delay variation of an amplifier distributing 10 MHz, and
noticed a regular sinusoidal pattern, about a third of a nanosecond
peak-to-peak, with a period of about 70 seconds. This looked like
interference from a
Hello guys,
some time ago we talked about curious humps in the ADEV of the SRS PRS-10 Rb
at around 20s intervalls.
I think I may have more info on that (and as usually that raises more
questions):
