Glen, with the new chassis we can standoff at least another 3/4"...

All over but the testing and shakedown....
Great. I got mine at 1-5/8 high, so probable leave the ones I did alone. I was doing it just to allow extra air between the board and backplane.

Joe , that was in "Level" mode, there are no filter options in "Level" mode. However, in Amplitude/Noise mode i can switch in Band Pass filters, Bandwidth Limiting Filters and Weighting Filters......I did not do that.........yet.....

You usually kick in the 30KHz filter. Noise in the 30-80KHz spectrum is interesting but not very relevant.

To be consistent between us, is that the filter you use for checking residuals??
I check with 30KHz on Lee but also look with the 80KHz filter as information only. I also measure with the HP3478A which has a 100KHz bandwidth for correlation. At these low levels, cables, shielding and proximity are contributors.
