Hi all,

This is a _fantastic_ device. ?I'm having tons of fun. ?Quick UI question: for a normal SA, there is the video bandwidth (VBW) setting independent of the RBW to average down the noise. ?Where is this equivalent function located? ?I'm sure it is in an averaging setting, but having trouble finding it.

There is no left/right pixel averaging (or filtering) as in a regular sweeping SA but in the LEVEL/CALC menu you can choose AVERAGE 4 or AVERAGE 16
These are both running averaging filters, good are removing noise but they maintain the information of each pixel as these average over sweeps i.s.o. measurement points
It is possible to add a VBW setting but does this add so much value?

And yes, the CALC menu will move under the DISPLAY menu instead of the LEVEL menu in a next FW release

I should have answered: Read the wiki:?

Thanks, Erik. ?No need to implement VBW - I can use the averaging functions. ?The only final comment is that if someone is coming in from a full-featured SA, they might wonder the same as I do. ?One could solve that by perhaps putting a VBW entry in the Wiki and pointing them to the existing averaging feature?

Good suggestion
