Erik, I updated the new firmware and PC software, but it still doesn't work.

Hi Hans, Thanks, excellent investigation. The SI5351 SW used was optimized for fast sweep for my DIY VNA so it is terrible with spurs.

Sorry guys, must have been a bit confused yesterday. Please use a new executable found here http://athome.kaashoek.com/tinySA/Windows/ and for those that already have the v0.2 HW, do update the FW of

erik, I connected the tinySA with PC software and the PC software is not displaying the spectrum properly and the spectrum on the tinySA LCD is not displaying properly anymore.

Hi Erik The Si5351A is prone to crosstalk between outputs, if the outputs are heavily loaded (e.g. 50-ohm loads). There's only a single supply pin into the chip. Other suffix versions of the Si5351

Erik, I receive a did different exception than Kurt.? ?The new version starts up O.K. automatically in the mock-up mode, but if I hit single the single sweep or run button I get the same string

Hi Erik After the nice warning clicked OK it started Repeated start it gave no error message, but in the mockup it gives new meassge, but of course I have no idea what is allowed Kind

Tom, For now there is no analog output foreseen. Display demodulated AM in volt (Vrms of the carrier) is being worked on so effectively it will behave like a digital scope. Now all I have to add is

Can you test if the updated version works better?

An analog AM bandwidth of 1KHz would be sufficient for tracking down utility power noise sources which typically generate 100 or 120 Hz fundamentals along with a few harmonics. The amplitude

=================================================== You're right Erik, The application loads OK in the mock-up mode, but clicking single sweep or run results in a "Input string was not in a correct

=============================================== Too late Erik.? I tried the executable before I read your reply and it ran without dll error on my Windows 10 x64 system (see attachment).? I received

==================================================== Kurt, In case you missed Erik's reply he has already re-uploaded a release version that runs in a mock-up mode. I just tried it and it runs fine

Argggggg Do not try, something wrong

Hi Herb Thank you for the info, then I was right ? I am sure Erik will send me one when needed or put it on the group Kind regards Kurt Fra: [email protected] <[email protected]> P?

My mistake, Release version uploaded. Can you test if this runs? When the selector bock pop's up you can select "mockup" and the SW will run with a simulated source

Kurt, You are correct, the "D" suffix indicates the executable that created the error is not a release version and not normally intended for distribution ( for software debugging as you noted).? The

Hi Erik I downloaded the http://athome.kaashoek.com/tinySA/Windows/ and when starting it reports MSVCP100D missing. As far I have figure out it is a file implemented in the code for debugging code

Internal flash allow minimum 10k write cycles (as in datasheet) Possibly use external SD card for this, and use simple SPI transfer mode (easy connect to display SPI
