Did you connect CAL and RF with the supplied coax before running the selftest?
If yes, can you try another coax?
If still fails, contact your seller for a resolution

On the touchscreen, the waterfall option is actually located at the DISPLAY tab which is fifth (5) from the top. So, is the wiki instruction a typo? Anyway, sending either 'menu 6 2' or 'menu 5 2' doesn't toggle the waterfall option. What is the correct syntax?

Are you running an old FW?
menu 6 2?
works for me

Sending 'freq 10M' can pause the sweep. So, how do I read back whatever information (freq or amplitude) that is at the measurement frequency?

Use the marker command after positioning the marker correctly
marker 1
reads out all the data from the marker

Re: Measure frequencies down to 500khz with tinysa?
500 kHz (please notice CORRECT abbreviation or kilohertz) using the TinySA?? Yes, it covers even lower than that.?
If you want 500 kHz, why do you reference a nominal 900 MHz (note correct abbreviation of megahertz) antenna.? No, this is not a loop antenna.? I really don't know what they are hawking for sale. ? Nor is it appropriate for 500 kHz.

Yes Toni,
V0.11.7 and v0.10.6 only show the top bmp

To access files on microSD? I use NanoVNA-app v 1.1215.0 (mod from DiSlord).

Re: #software QtTinySA v0.11.7 release

In the Windows executable when you look at the contents of the SDcard (File/Browse TinySA), if you select a .bmp file you see it on the screen, this is fine, but when you select another bmp file, the screen shows you the previous bmp file seen, and Save, it also saves the previous one seen. Does this happen to everyone or is there something I'm doing wrong?
?
Thanks,

Re: What to do when a selftest fails
Can you do a manual calibration??
Input a known level (CAL output should be OK) and use
CONFIG/MORE/LEVEL CORRECTION/INPUT LEVEL to set the actual input level
If this works and you now get the right level can you retry the calibration?
It seems there is something wrong with the LNA anyway.

Re: What to do when a selftest fails
Erik,
Please find photos attached..
ch> selftest 0 3
ch> selftest 0 4
ch> selftest 0 4
ch> selftest 0 10
ch> selftest 0 11
I checked with sig gen and oscilloscope for measured value and the value appears to be fairly close to scope value. The 30mhz calibration waveform also appear to be correct. The Signal generator was very weak output and not as selected on screen adusting the offsetvalue of output seemed to bring it up to expected value but it was still unable to perform either test with success. Have also tested with known good cables.
Have downgraded firmware also same issue..
Hope this makes sense..

Re: What to do when a selftest fails
Before calibration restart the device with jog button pressed to the side?
After this the level indicators should be red as the calibration is removed and all settings are factory defaults
Then try again the calibration
If this fails post a picture of all failing selftests using the usb command
selftest 0 x
where x is one of the failing tests

Re: What to do when a selftest fails
elecshop is NOT?on the vendor approved list in the WiKi.So despite what the vendor said, it might not be true. I have been told by a few vendors that said their TinySAs were original, so I purchased one and it was a knock-off. So, if a vendor is not on the approval list in the WiKi, you are probably not going to get an original. Just saying. CLYDE KC7BJE?

Would really appreciate to determine if this is a hardware fault or can be fixed.
Attenuation test passes as per wiki advise.

Asking about the option -N in python code
Hi all,
I recently bought an ultra tinySA, and it’s amazing that we can fully control the device using Python. Thank you to the team for such great work!
I followed the code from , using the -N and -o arguments to set the number of points and output the measurements to a file. However, the code always selects the number set by the device itself (in Display/Sweep Points) rather than using the number specified in the -N argument.
Could you please help with this issue?
Thank you

Uli,
I am running latest version here with no problem on bookworm (Debian 12), I use the git repo.

ldd (Debian GLIBC 2.36-9+deb12u8) 2.36
Hope it helps your fault finding.

Re: Level calibration question
Thanks to everyone responding, I'll try at that frequency and level?

Re: Level calibration question
after calibration at different signal levels the error does not exceed -+0.5dBm
why not? for ultro it is applicable, only you need to take into account cal= -36dBm 30mhz and perform calibration according to this example, or as I previously dropped using rtl-sdr comparison method.

The Ultra uses a different calibration level,?
