Entry number 386924

This entry is a followup to: 386921

Looking at the output of the offset/attenuator boards on L-HRS we see
a ringing of amplitude 20 mV peak-to-peak on a signal of nominally 200 mV.
The ringing has a period of 6 usec and affects all channels.  The output
shifts slightly (30 mV) when we unplug the input.

We moved a board to another NIM crate -- similar ringing.

This looks like the source of noise but I'm not sure how to solve it at
the moment.
