Re: frequency correction

I checked.
On purpose I let the resolution filters overlap somewhat? so this helps the interpolation.
There is no I/Q signal and FFT but 57 resolution filters ranging 2.4kHz to 600kHz and then a

Re: frequency correction

That little bit of code I put here only really helps if the carrier of interest is somehow spread across 2 or 3 spot frequencies (bins in the FFT world). Otherwise it has little to no effect at

Re: frequency correction

You can get a better frequency estimate for a marker that is set to "Tracking the peak". I modified this bit with some extra code to estimate the actual carrier frequency ..

Re: Video bandwidth vs. RBW setting?
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.

Re: Video bandwidth vs. RBW setting?
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

Video bandwidth vs. RBW setting?
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.
