For now there are sufficient candidate testers.

Hi Erik Agree, removing any additional contribution on the two sideband frequencies from the two signal generators by using power combiners with isolation and other means such as isolators, will

But the internal generated IIP3 can not be higher then what is measured so I assume this measurement set a lower limit for the IIP3 of the tinySA, it could even be better. Correct?

Hi Erik I have a few comments/suggestions. I do not know how you test setup was, but there is a need to ensure the IIP3 level is not influenced by cross modulation between the two signal generators.

With FM modulation the zero span graph does not show the modulation but a simple trick can help. When you look at the close in spectrum of a FM signal using a wide but steep RBW the signal looks like

The tinySA can be used as a signal generator and in low output mode there are some options for modulation. Using the AM modulation to create a 10MHz signal with another tinySA in zero span mode it is

I hope you remember us little people when you become rich and famous :) Can you share when you think the commercial version will be available?

Erik, I would love to test out this TinySA and have been with the project since December of 2019 and have a version built up like you did on protoboards. I have A LOT of test equipment at hand

Greetings Erik, A common problem for radio amateurs is the proliferation of modern day RFI sources that cause significant interference particularly to the HF bands. IMHO a portable low cost spectrum

Erik, Once you are ready to release the full list of console commands for the tinySA, I would like to see if I can translate? the python nanovna.py class library to the tinySA (tinysa.py?).? No

Hello, i can help you vs test tinySA My main job is the development, repair, maintenance of aviation communications systems. Therefore, I have the opportunity to test it on various equipment (compare

Hello, i can help you test tinySA My main work is development, repair, support of aviation communication systems (i not programmer, it my hobby, but i can help vs software) It is possible to check

I have no idea, I only do "back end" development and these days it is almost 100% in Go on Linux. Mono is supposedly .NET compatible and supported by Microsoft so libraries should be compatible but I

1. Very, happy to see selectable front end attenuation.? One of the best ways to determine if a signal is real or not is to add rf attenuation.? If the signal stays at the same level you know it is

Does mono have a decent graph object?

If I remember correctly you are using .NET? Maybe look into Mono for future cross-platform projects?

===================================================================== Erik, 1. Very, happy to see selectable front end attenuation.? One of the best ways to determine if a signal is real or not is

================================================== That's pretty nifty.? Sort of like the old HP8445/HP8568 set-up.? The synchronous tracking should allow for additional depth when sweeping filters.

Kurt, Can you confirm I'm doing the IIP3 measurement as it should be done?

I'm not able to create such an application but as the tinySA console commands are very similar to the nanoVNA a derivative of nanoVNA-saver becoming tinySA-saver should be not too much work.
