Re: Linux Mint USB #tinysa

 

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 am able to use both my tinySA and my tinySA Ultra with Linux Mint 20.3 Cinnamon and tinySA-saver 0.2.2.? Are you using the latest version of tinySA-saver from github?



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.

Forgot to mention this wiki entry that explains how calibration above 5.34GHz is done:?

Simplest is not to enable the LNA and everything will be correct

Re: "CALIBRATE above 5.34GHz" throws a "Signal level too low or not on frequency" error #bug_report

 

Did you input a 5.34GHz signal between -50 and -10dBm when calibrating above 5.34GHz?

"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.

?
Any ideas on how to proceed prior to returning it to the vendor?

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

Sure that would be great.

Re: Harmonic measurement. Question for Eric

 

John.
Could that be done as with a second keypad when you enable harmonics measurement asking for the attention of the fundamental?

Harmonic measurement. Question for Eric

 

Eric,
When I measure harmonics I always use? well defined high pass filters that suppresses the fundamental by >50db. The commercial spectrum analyzer I use at work lets me input the attenuation of the fundamental as a value in db. This permits the measurement of harmonics that are very small (-110 to -120dbc) without overloading the front end. Would it be possible to do with the ultra? It should be just a mathematical function that doesn't impact the function of the analyzer it self. The read out would be the reduced fundamental + offset , and harmonics in dbc to the combined fundamental value.

Re: My tinySA Ultra Signal level Critical #ultra

 

There is either something wrong with the first switch or with the LNA
The new FW detects this and refuses to calibrate

Re: My tinySA Ultra Signal level Critical #ultra

 

When I turn off LNA? I generate CAL out at 30Mhz it work fine .




But I turn on LNA look like this.




I backed to the old firmware.

With the latest FW the selftest will do a better check on the LNA

Where can this be bought, please, Larry?
Not that it's likely to be economic for the UK, though.

I did search and find:

but no purchase price.
