Unfortunately it has to be very accurate, within 1 kHz, See? Let me see if there is a possibility to relax this requirement. --

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.

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 answer.
There is a learning curve to Linux but I want to thank all of you who guided me in the right direction.?

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 accurate, but I suspect that it would be closer than with the step, particularly around the transition point.

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 failed: [Errno 13] could not open port /dev/ttyACM0: [Errno 13] Permission denied: '/dev/ttyACM0'
For some reason in the TinySA program the USB port is /dev/ttyACM0 but there is no communication with the unit and I did rescan and I get /dev/ttyACM0 again no communication when I press Connect.
I have the TinySA Ultra on the way from RL Electronics and would like for that to work.
Thanks Ed kj4fgi

I have heard some have had problems connecting with USB3, but USB2 works OK.? If you have problems with one, you might try the other.? Try hitting the rescan button if saver doesn't see your tinySA.
I hadn't used tinySA-saver in some time and just installed the latest version recently when I got the Ultra.? I used
git clone
in a terminal to download, then used cd to switch to the newly created folder and followed the directions for Ubuntu in the README.MD file, except that I just used python3 where the instructions specified python3.7 since Mint 20.3 is using python 3.8.10 and will use that automatically when given the command python3.? Python3 and pip were already installed, so I ignored that part of the instructions to install those.

"CALIBRATE above 5.34GHz" throws a "Signal level too low or not on frequency" error
#bug_report
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 100kHz to 5.34GHz" passes.
?
Did Config/Clear Config/Config/calibration several times using both provided leads, resulting in same error when calibrating above 5.34GHz.
?
Version: tinySA4_v1.4-40-g2f63e1c
Build Time: Jan 13 2023 - 17:56:59
HW Version: V0.4.5.1 (167)
?
Any ideas on how to proceed prior to returning it to the vendor?

Re: My tinySA Ultra Signal level Critical

If I temporarily disable LNA, will all my measurements still be correct?

Re: Harmonic measurement. Question for Eric
Sure that would be great.
Thanks
