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.

Use DISPLAY/SWEEP TIME setting to reduce the sweep speed
Use LEVEL/TRIGGER menu to enable a pre-trigger so the whole screen is used and set trigger to NORMAL and set the trigger level
You only have limited amount of pixels horizontally some many transmissions will not fit on one screen
