TinySA as an RF scope in zero span mode

 

Hi Folks,

I recently tried to use the TinySA in zero span mode at 433.92 MHz to look at the pulse train of a remote key fob.

It does show up, but the sweep speed is too fast and? I can't get the whole train in view, nor can I figure out if I can save it on screen.

I want to be able to identify the pulse widths in order to replicate the waveforms accurately with a 433 MHz eBay module.

Does anyone have any experience with this? I cannot afford a 500 MHz and up scope.
