Re: RFI Source Identification Signature Storage Application

 

Will be a good solution for a future 4" version of the tinySA. In the 2.8" version there is not enough spare space at the edge of the PCB to place the SD cardslot

As the internal flash can endure above 10k write cycles I assume using the internal flash with a warning not to store too often is OK.

Saving settings to one of the internal memory slots now also saves the stored trace and loading a saved setting will restore the stored trace.

This provides 4 memory slots to save traces?
At this moment i implement SC Card support for NanoVNA H4, it very simple and good work. Use SPI interface some as display, need only SD_CS,?SPI_MOSI,?SPI_SCLK signals (SPI shared vs display and work on some speed), good if exist SD_CD (for SD card insert);

It very low cost solution, need ~7kB flash and ~600 bytes RAM for full dile read/write Fat16/32 support (can extend, use FatFS lib)
Re: TinySA Frequency Range

 

And some practical?examples
First DECT traffic just below 1.9GHz and second WiFi traffic around 2.45GHz. Red line is current signal, yellow line is power envellop

Re: TinySA Frequency Range

 

Having full control over the internals of the tinySA allowed some experiments at higher input frequencies using the mixer and BPF in a creative way. This of course required the elimination of the low input low pass filter.
Here you have a short set of screen captures that demonstrates a slightly modified tinySA is able to measure higher input frequencies with some limitations as at least the power level is not reliable. Once solved, this has promise to? become a "tinySA special", or an opportunity for hackers
The input is an ADF4351 set to 2.3GHz, 2.4GHz, 2.5GHz and 2.6GHz. TinySa settings are identical in all 4 measurements.

Re: Hardware availability?

 

I will adapt the wiki to show the status of the availability of the HW
Re: Hardware availability?

 

Thank you all that responded. I only wanted to be sure that the hardware was available or still not. Since I read a lot of messages in the group I was not sure if I had missed the launching announcement.

Thank you again.

Best regards,

Ignacio EB4APL

The usual response to questions like that regarding products still in development is:? "It'll be ready when it's ready."
Re: Hardware availability?

 

Shipping times are terrible and not all beta testers have received the HW yet. Once they have access we have to wait for their feedback.
Re: Hardware availability?

 

Hola Ignacio,

I have made the very same question today! And because of the same reasons...

Anyway, I was redirected to:

???? Yep, it works now.? Thanks a bunch!? I like being able to get it on the "big screen."? These old eyes don't like that small stuff anymore.? I had to get headband-type magnifier with 5 different lenses to solder some surface mount stuff recently.
Re: TinySA-saver updated

 

Jim,

Everything in tinysa-saver now only uses the tinysa name and (if I did not make any mistakes) you should be able to install it on your system next to having nanonvna-saver.
You can also download the repo and run it directly from the commandline
python tinysa-saver.py

Remember:
- In display setup: close all views except "S21 Gain" and check "enable lines"
- Set tinySA in low or high input mode as tinysa-saver can not do this.
- One sweep contains 290 points and you can set as many segments as you like
- Any manual tinySa setting like attenuation or RBW has to be done on the tinySA itself. Nothing available yet in tinysa-saver. But as these are by default in automatic mode everything should work.
- Make sure you keep the start/stop frequencies in the selected low/high mode range

Multiple segments is now working in tinySA-saver


The tinySA data is in the S21Gain (dB) graph. Suggest to remove all other displayed charts except S21 Gain
Make sure you set the tinySA in high or low input mode before running tinySA-saver
Screen capture works. See "manage"/"screenshot"
Apart from making the data visible I did not do ANYTHING to make it robust

Hi Erik and others

It works OK when remembering to set frequency start and stop before doing a sweep. On the TinySA the Attennuation and reference level must be set to manual in particular for Multiple segments and if so set I got it to work just fine

Thank you for the effort

Kind regards

Kurt

Re: TinySA-saver updated

 

I cloned the tinySA repo, then attempted to install just as I had installed NanoVNA-Saver in the past, substituting "tinySA-saver" for "NanoVNA-Saver"? in the command.? It didn't install.? Looking through the files, I see that everything in them is still named NanoVNA-Saver. If I install this, will it uninstall any previously installed versions of NanoVNA-Saver (which, of course, many of us have)?? Does it retain all the original NanoVNA-Saver functions, so that one program now works for both SA and VNA?
New measurement example: Spur Free Dynamic Range

 

A new measurement example is added to demonstrate the dynamic range of the tinySA in measuring harmonics coming from a transmitter
