I've updated this page: https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Harmonic to include a manual method to calibrate the harmonic jump in case you have a generator at 5.34GHz with lesser frequency

Hi Erik, I missed that one part in the tinysa.org wiki. Thanks. Unfortunately, I don't have an accurate 5.34GHz source. I can work with just the initial calibration and lower frequencies available. I

Thanks Erik Jeff

Yes -- For more info on the tinySA go to https://tinysa.org/wiki/

Unfortunately it has to be very accurate, within 1 kHz, See https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Harmonic Let me see if there is a possibility to relax this requirement. -- For more info on

Thanks Martin!

Hi Erik. How accurate must? the frequency? be? I inject a 5.3420 (that's what my source steps manages) and abt.-20 dbm, and still get the 'Signal level too low or not on frequency'. TIA??? Joe.

Ed, Just remenber: Linux is really user-friendly. It's just very picky about who its friends are. Martin

Thanks Erik Kaashoek.

Problem Solved! Thanks to all who helped, my problem was Did you install the udev rule? Are you member of the Group "dialout"? I googled Permission denied: '/dev/ttyACM0' and was able to find an

Thanks Erik I assume that leveloffset harmonic is accessible from the console commands? 73 Jeff G8HUL

There is already a default value set to minimize the step when transitioning to harmonic mode but due to manufacturing tolerances this step is not equal for all tinySA Ultra. The uncertainty is

Hi Erik On a similar theme; I do not have a 5,4GHz source, so is there a way of manually entering a cal value so as to smooth out the step at 5.4GHz? I realise that the calibration would not be

Ho-Ro I have no idea, I am new to linux, I am not a member of dialout, I don't even know what it is Thank you for such a quick response Eddie kj4fgi

Did you install the udev rule? Are you member of the Group "dialout"?

Thanks Jim, I did that, the program opens but won't connect to the TinySA. I get this in the terminal window 2023-01-18 02:08:23,923 - TinySASaver.TinySASaver - ERROR - Tried to open /dev/ttyACM0 and

Forgot to mention this wiki entry that explains how calibration above 5.34GHz is done: https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Harmonic -- For more info on the tinySA go to

Simplest is not to enable the LNA and everything will be correct -- For more info on the tinySA go to https://tinysa.org/wiki/

Did you input a 5.34GHz signal between -50 and -10dBm when calibrating above 5.34GHz? -- For more info on the tinySA go to https://tinysa.org/wiki/

I just purchased a tinySA from one of the vendors listed at tinysa.org. When running the "CALIBRATE above 5.34GHz", the test throws a "Signal level too low or not on frequency" error. "CALIBRATE
