In the tinySA Ultra, there is a bug in the USB interface output. Compared a signal -40dbm signal on tinySA and tinySA Ultra,
tinySA.exe and also the tinySA-App.exe (211),? => the Ultra shows level shifted up by ~ +45dbm
bug or feature - or did I mess up my settings on the Ultra ?
Wolfgang The tinySA.exe does not automatically recognize you are using an Ultra and it does use the wrong scaling factor as herb previously explained. tinySA-App.exe should be ok though, at least I do not see something wrong there. ? --

Re: Unable to get Listen to work on Ultra
For narrow FM band you can set RBW to 30 kHz.

Re: TinySA Ultra - Hardware version "unknown"
I had the protection film at the beginning, too. But it worked.
I just remembered something. Is it possible to move the calibration points for touch calibration a little bit to the middle of the screen? At the moment they are exactly in the corners of the screen. You need a very thin pen to calibrate. Most of touch pens are a little bit bigger and you can't reach the corner exactly.

Re: Preferred behavior of MARKER->REF LEVEL
?Thanks.? I forgot I¡¯d downloaded that. It¡¯s quite good, and it shouldn¡¯t take too much effort to revise it to match the Ultra.

Re: [tinysa Ultra] readability improvement
I have a minor complaint regarding the way zero digits appear in the display. Along the left side and across the bottom, 0¡¯s do not have a slash through them, but values shown on the grid do have a slash. My old eyes often mistake the slashed zeros for 8s. It would be more legible (and consistent) if the slashes were removed, unless there¡¯s a good reason for them.

I just watched IMSAI Guy's video on using the SD card, and learned
to click on the SD icon to save the screen. Cool! I did so, and it
worked without the wrapping mentioned before.
Someone will surely produce a manual for this pocket miracle
eventually, and it will be a great help to many users.

With my TinySA Ultra it works, but the noise level which is -90 dBm on the TinySA is shown as -45 dBm in NanoVna-App 1.1.211. Am I doing something wrong?

? ? Looks like a scanraw conversion error by the programmer.? The tinySA uses a scanraw conversion value of -128, whereas the tinySA Ultra uses a scanraw conversion value of -174.? That's a difference of 46 and pretty much matches your error. Herb
