Hi,
Yes outliers removal creates gap in Stable32.
The « fill » function can fills gaps with interpolated values.
It does not change much the graphs, except in the low Tau area (see attached).
Do you know a discussion of impact of outliers removal ?
Gilles.

My noise floor is fuzzy. The bottom is -110, even when the display goes down
to -120. The fuzz is ~3 dB.
My 10 MHz birdie looks like it is
Hal, my 10 MHz birdie is at a level of about -95 dBm, which puts it a

I've found that the "spur removal" function sometimes works, but not
always, if I
change the IF frequency setting to 433.9 MHz. It's mostly bimodal behavior-
sometimes

Hi
As you throw away samples that are far off the mean, you reduce the sample
rate ( or at least create gaps in the record). Dealing with that could be
difficult.

Have you looked carefully? I have to zoom in on the bandwidth in order to see
it. Somebody else called it a birdie.
My unit came from R I'm reasonably sure it's genuine.
If I look at 10 MHz center and 25 or 100 k span, there is

Hi,
I tried something with the idea to consider night records fluctuations as

BTW, I did purchase my 10MHz-"leaky" TinySA through R & L. Had I not had
the clue that R & L was a reliable source, I would never have ordered one ot
these things at all.
Tom, I don't walk around- I pedal around on a recumbent trike.

The software is basically open source so anyone could theoretically make
