Did you use an analog oscillator or an analog notch filter? There is a much larger difference when doing that. Dacs not so much because the foot stays narrow. I’ll post some results using an analog notch tomorrow showing much larger differences.
I thought you were saying that a one octave discrete notch filter will make a large difference in noise measurement at 10k but not at 1k. That’s not what those results show. What would the analog notch demonstrate?Did you use an analog oscillator or an analog notch filter? There is a much larger difference when doing that. Dacs not so much because the foot stays narrow.

I needed a break so decided to implement the units for the level sweep (@pma). Unfortunately, the setting is still called 'vertical units' in settings There's also more to work on in the sweeps, but at least this part can be tested now:

Ah, I assume you switched the units selector a few times after the sweep was completed, am I right? I think it just keeps adding the last point to the end of the plot, each time you do that. I'll fix it.

EDIT: Should be fixed now https://app.box.com/s/ue7ll9xmvwogst817x2l1xg09opvgy47
Should be fixed now, thanks!Yeah, actually I did. I didn't realize that it was because of that, but now it's clear.
Every second time (about) I do a log chirp the signal green bar stays on after it finishes as if some short of signal still plays:

(did the same with level sweep some time ago but it was fixed in the next versions)
Yes,it stops.If you press the Stop button again, does it stop then?
Still have them.Me too, problems with stability. Had it for years.
Wait, are we talking about the software?

Specially after some alcohol .
Yes,it stops.
Probably my ancient drivers
Here's a couple findings:
1) Sometimes I get this error when I change the vertical unit selector to dBV after a sweep (Sweep made for example using the dBFS unit as selector):

Usually it happens when changing the unit for the first time. For the second changing it's usually ok.
2) Every time I change the vertical unit selector to W after a sweep (Made for example using the dBFS unit as selector) I get a black screen and no graph.
3) It still is unable to stop the measurement when sweeping sometimes. It seems to happen more often when the sweep end is set to "0" and the signal clips heavily. Not so often or even ever when using the negative values.
1) Do you have a full capture of that error message? It might tell me where it's occurring, as I can't reproduce it
2) Do you have Resistance and Volts (FS) configured to something other than 0? A zero would result in no data being displayed:

3) When you say you can't stop a sweep, do you try to press the stop button and it doesn't stop, or does it not stop on its own, after reaching the end of the sweep?
