TinySA Ultra launched

I vote @shapirus reports the bug, he found it, I was just confirming it.

The creator Erik Kaashoeck is a regular user here on EEVblog, and likely quite ajour with this thread.

Even better! No effort bug reporting. 😉

Not via google groups, sorry. Not gonna go through the associated setup hassle.

But since the author is registered on this forum, let's mention him.

@erikka , do you consider this one a bug, a glitch, or a feature? :)

[KungFuJosh]

There's an option in the config settings for better accuracy OR cleaner signal. The glitches exist either way.

The tinySA does not do a continuous sweep but sweeps in discrete steps with possible silence in between. Set the scan speed slow and you will see the step

What are the random frequencies that appear between steps?

[erikka]

PLL's locking after the step
I do not mute the output as this would slow down the maximum sweep speed and created larger gaps which you will hear as stronger clicks.
Any stepwise sweep will always have some form of artifacts

Can you explain why these may be a problem?
Or is this just curiosity because of what you saw on the DSO?

[KungFuJosh]

For me, just curiosity.

[shapirus]

More like a cosmetic issue, having all those random waveforms displayed between steps, especially since it's not the primary function of this device.

It would be nice if it could be fixed without compromising other functionality, but otherwise no big deal.

[erikka]

Please explain why it should be fixed, except for cosmetic reasons when observing with a DSO?

It may be important in any practical application where a frequency sweep signal is used and it's expected that the signal won't contain any frequencies outside of those expected at any given time in the sweep range.

I'm not sure what those would be, I dont have any examples of my own.

[erikka]

If you need that, you should buy a SG that does a true continuous sweep.

I never argued with this. I just said that if it could be fixed without compromising anything, then it would be nice and would benefit everyone. If it's not possible, then it's not really an issue.

[KungFuJosh]

Maybe a "clean sweep" option in the settings to make it possible for those that prefer it. For those that might prefer the clean results to the speed of not having it muted between steps.
