Re: New tinySA control program for Windows
I'm a bit confused with respect to scattering parameters S11 and S21 being shown on the display, when being used as a SA.
Regards,
Martin

Description:
This is the nanoVNA-app adapted for use with the tinySA.
It should also still be compatible with the nanoVNA
The conversion is not finished yet so co-existence with nanoVNA-app.exe may cause problems with the ini file

Re: Detecting a noise source
You have an excellent tool to trace it.
Set the span to scan ( some of) the interference frequencies, eg 3-14mhz.
Put the telescopic aerial on the lower sma socket.
Extend the aerial and see the noise spikes on the screen, then walk around the house/ garden/ street, observing the amplitude of the noise spikes. ?As you get nearer and the spikes get larger, collapse the aerial down a bit. Eventually you might get to within a few feet.
I identified a switch mode psu in the house which powered an electric reclining chair within minutes this way - one if the first uses of the device. It is possible to use handheld directional aerials ( or a mw ferrite rod aerial from sn old aerial) so that you can triagulate the source if distantly generated noise.
On the wiki for the SA, you will find info on using an external lna (low noise amplifier) to increase sensitivity so as to be able to detect more distant noise sources. I am in the process of making one, which I will probably velcro to the sa case.

Yes. The latest build is V1.0-91 and you are running V1.0-61 Pleas upgrade. Read the wiki for guidance how to upgrade

Hi Kurt, Hope this finds you well.
With regard to the User Guide you produced for your presentation about TinySA in Danish language.
I think you indicated you may produce a copy in english, forgive me if I missed it but would be very interested in getting a copy.
I have read several of your documents and I'm sure it will be a very handy asset for the shack.
Thanks in advance.

Why do you use TDR instead of? log mag S11?

Hi Herb, I used the settings I see on your example to the letter, but no luck yet. How did you get that pic of the device in there?
? Sorry you are still having no luck with a scan.? The program has a 'Capture Screen' button on the left hand side of the screen which pops up a screen capture window.? I just overlaid that window on top of the chart.? You might try doing a screen capture just to prove to yourself that everything is connected correctly.

Dave, DfuSeDemo can only be used to back-up your current firmware or load new firmware.? If you want to view your current correction data you have to do the following: From a serial terminal enter 'correction' and the tinySA should respond with your current correction factor table, refer to this wiki page:???. - Herb? ?

Hi Herb, I dropped a screenshot in reply to Erik's request. I have my device set at 240-900 MHz since there is some activity on 750 and 850 MHz around here. When I select Log Mag S21 I get nothing. To get the black trace at 10dB I have to select log Mag S11 and S21. Curious and interesting.
? I hadn't used the control program on the high port yet, but I just tried it and it seems to work - as shown in the following screen shot.? As you can see selecting Log mag S11 and then the 'Single' or 'Scan' controls results in a trace of the tinySA display.? Selecting Log mag S21 and then the??'Single' or 'Scan' controls gives you a solid line because the active trace data is contained in S11 and not S21.? Give the settings below a try and see if they help. ? ?  ?- Herb

Re: New tinySA control program for Windows
Yes if he gets stuck I'll guide him if he needs it. There is like 20 or 30 thousand lines of code (or more) there I've already written for the VNA past month or so, so he's off to a good start there !
I fancy a holiday now though, can't go anywhere (the UK has just gone exponential again with this virus so lock downs are on their way back) but I can relax and do nothing and do what ever takes my fancy when I fancy :)

Hi all,? I downloaded this app but am unable to get it to show a valid trace from the device. Are there any settings I should be changing to have it read? All it does is give a black solid trace at the 10dB level.
If I select log mag S21 from the drop-down box (as in the following screen shot), I will get a solid trace but not at 10dB level.? The active trace is S11 in the tinySA control program and has to be selected in the drop-down box (or select log mag s11 and s21).? Give that a try.? Use the example below for other settings.  - Herb
