No new App version now or expected in the near future
--

Just uploaded/installed the firmware 1.1-59 DFU file via the app V1.0.240.5.

It works fine - Thank you Erik.

Question regarding the windows App.

I am using the version 1.0.240.5. Do you have a new version available at this date?

All the best

Even worse, I forgot it was already implemented.
Use the "offset" command, just like when in SA mode

New FW release : see http://athome.kaashoek.com/tinySA/DFU/
Version v1.1-59

Changes:

Not yet (I forgot.....)

Very nice feature!
Is the function implemented as a console command too? I could not find anything in the response from the "help" console command...
I have tried it with a screen input and it's very nice!

Output level to be set as -6dBm, 20dB external amplifier resulting in an output signal og 14dBm and the output level indication is 14dBm. Output level can now be adjusted to 10dBm and the "internal" level will automatically be adjusted?to -10dBm, but not shown on the display.... is this correct?

Example is correct. Amplification can also be negative (attenuator)
The value displayed is the level after the amplifier/attenuator. Goal is to eliminate the user having to do a calculation everytime the output level is changed.

Hi Karl,

I can not replicate the bug.
These are the commands used:
mode low output
level -50
output on
levelchange 30
and the 10MHZ signal swept from -50dB to -20dB.
Can you list the commands that replicate the bug?

I did a quick test using an ADE-1-24 mixer and a 433.9MHz TX module. I don't know if I ran the risk of burning tinySA, but the result was interesting, considering that I didn't use any filtering on the 433.9MHz TX.

? ?I performed a similar tracking generator test using an external mixer, and my dynamic range was limited to around 30dB. Quoting Erik ...

? ?The 30dB limit comes from leakage of the external LO through the external mixer from its LO port to its RF port to the tinySA high input port into the tinySA mixer. As your external LO has probably something like +10dBm and the LO-RF isolation of both mixers is maybe 20dB you get -30dBm on the RF port of the tinySA mixer. To block this leakage path you best use a 30dB attenuator and a 25dB amplifier connected between the tinySA LO output and the RF port of the external mixer. This provides substantial extra isolation and thus extra dynamic range.? I get at least 80dB dynamic range.

? I get equal or better dynamic range from my NanoVNA-H4 using S21 two port measurements, so I never got around to actually testing the isolation amplifier/attenuator set-up.

Hi Erik!
I have tested the sweep generator function, and I think there is a bug in this function. The console command for increasing amplitude is not working, "levelchange 30" should start with a "low amplitude and increase it 30dB. This is not working, while the "levelchange -30" workes nice!
I'm not sure, but I think this was working earlier, but I don't remember which version I was running, perhaps the version I got when it was new. I have tested both version 1.1.59 and 1.1.52. I also tried version 1.1.32, but the "levelchange 30" is not working in any of these.

Very nice job you are doing, thak you very much!

I will soon publish tinySA Generator program soon, it's a Windows program controlling the generator functions on the LOW output only...

A Japanese tinySA user made a nice tinySA-App manual,
Thanks to google translate also easily readable for those that do not understand Japanese

Another suggestion. Wouldn't it be better to change the value from -76 ..- 6 on this screen, to the corresponding value by adding or subtracting the value of the external AMP?

Yes, but I was too lazy to change the help text, its a static text and making it depend on the amp setting is a nuisance. The text is not used to limit the input so you should be able to use the whole range. (-116..-46 in your example)
Changing the help text is for the todo list

Erik, I am so happy to see that you added the external AMP in RF generator mode. Thank you very much for accepting my suggestion. Of course I ran to do the tests, I noticed a small problem. If you turn on tinySA, go into generator mode, set it to -67dBm and add AMP to -40dBm everything looks perfect,?


but only if you typed it once, because the second attempt is already wrong.

(NOTE: the APP was unable to take a picture of this screen, I had to use a cell phone. I use a Portuguese to English translator, I hope it is easy to understand.)

Hug and a lot of peace.

I would like to thank all of the learned members for their sage advice over the year and wish you ALL a very Merry Christmas.
