Using the 10Mhz cal output and one of the cheap Chinese MAX2870 PLL's sold at the different places (Amazon link only to show the model) modified to accept an external clock of 10Mhz gives me a 5.34Ghz

Are you in the dialout group? The error suggests you haven't got permissions to the device... Good Luck! Paul

Hi Erik and Kurt Thanks for the more 'manual' level calib. Certainly brings back memories of 'old time...' Will try it (ie.? play with) tomorrow. Be safe???? Joe

Hi Joe One detail I forgot to mention. In config set repeat to X10 to stabilized the marker level fluctuation Kind regards Kurt Fra: [email protected] <[email protected]> P? vegne af josephlevy via

Hi Joe You already got an answer from Eric, as the frequency must be 5.34GHz within 1KHz. However, the predefined harmonic offset is after a firmware update set to 10.5 and is not far away to what is

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"?
