New FW release: "audio AGC" option and reduced spurs

 

New FW release
Version V1.4197
For all tinySA Ultra and Ultra+ versions
?
Changes:
- Added CONFIG/EXPERT CONFIG/MORE/AUDIO AGC option. When disabled the PCB edge point PA4 will in listen mode have a voltage linear with the signal level in dBm Useful for integration of tinySA as selective power meter
- Reduced level of internally generated spurs on multiples of 10 MHz not being multiples of 30 MHz (ZS-407 only)

Re: Self-test error and does not continue

 

Just to rule out the obvious.
Did you test with different coax cable?
Is the call output set to 30 MHz visible on a scope?

Self-test error and does not continue

 

After checking the low RF output in the generator function, I ran the self test. But the self test failed, stopping at item 3 and not continuing.
I am attaching a photo of the test attempt.
I have had this for 5 years and have never updated it. But it has always worked perfectly.
The current firmware is version: tinySA4_v1.4-49-g4f5396a.
Model: TinySA ULTRA
I would greatly appreciate any help.

Re: connecting to macOS to issue commands

 

Thank you!
?
So I did
python ./tinySA.py -e 'leveloffset low output -1'
?
and also in the same vein
python ./tinySA.py -e saveconfig

Re: Pre-sale, tinySA ULTRA plus

 

I know it can be bought from the Zeenko store on AliExpress, but that means wasted time with customs formalities. It was preferable to be able to buy it from the European Union.

Yes, I did, the response is like this:
?
% python ./tinySA.py leveloffset low_output -1
Usage: tinySA.py: [options]
?
tinySA.py: error: no such option: -1

Did you forget the underscore between low and output?

Locked Re: Attenuation for Ultra

 

Let me add one reply and then close this topic.
?
Fur the ultimate spur free dynamic range you have to strike a very careful balance between the power level that arrives at the mixer and the noise floor.
If you want to measure very low harmonics (say below -70dBc) you can't do a simple calculation of the attenuation required as device variations in noise floor and mixer IIP3 need to be taken into account

Locked Re: Attenuation for Ultra

 

When one KNOWS the source power AND the input level to the test instrument that will yield a faithful
rendition of the input signal, one can EASILY determine how much attenuation is required.
PERIOD. P E R I O D......
..but unfortunately that figure for faithful rendition generally not known and has to be determined, as was the -25dBm for the TinySA, by trial and error, and does vary somewhat from unit to unit and with signal characteristics.

Re: connecting to macOS to issue commands

 

This is the response for calibrating the output level:
?
leveloffset low output -1.0
?
tinySA.py: error: no such option: -1
Re: connecting to macOS to issue commands

 

If you can capture the screen you do not need other drivers.
The tinySA is connected as a serial interface and you need something to send serial commands and show the serial responses.
This can be a terminal emulator or a python program

connecting to macOS to issue commands

 

Hello,
?
I want to connect to tinySA from macOS. I did it previously for updating a firmware (dfu-util) and now tried tinySA.py following the steps according to athome.kaashoek.com/tinySA/python/. Capturing the display was ok. The device is tinySA Basic with 1.4175 firmware.
?
Now I'd like to issue other commands, explicitly to calibrate the low output level.

But don't know which scripts are used in the drivers. I only found info that there are windows and linux drivers. Would like to try to install from source to macOS. Could someone provide a link? I searched github but appears that Ho-Ro/nanovna-tools are not the right ones.
?

Re: Ultra failing tests

 

If they don't want it back you can try to replace the switch

Re: Ultra failing tests

 

It looks like the RF switch on the RF port is damaged and Amazon may have sent you a return from another user. Suggest returning it for a replacement.

I don't see how it can be a clone, as it came 2 day shipping from amazon which
the tinysa site lists as a good seller. Don't the fakes also have firmware that
falsely shows the self-test as passing anyways?
You could try the latest firmware, perhaps?
