I'd love to play, but I don't have one of these scopes. I have an SDS2504X+ 500MHz scope.Well, it would still be an interesting data point. What's the lowest samples/sec rate it can do? The idea is to set it to the lowest sampling rate and connect it to a source that outputs a frequency sweep in the range from ~20% to ~60% of the sampling rate.
I can sweep up to 841MHz on my scope with the TinySA Ultra.It can actually output up to 5.4 GHz (or at least so the specs say), but it switches from sine to square wave above 800 MHz.
blk-grey-blk-blk?The value wouldn't start with black unless the multiplier band was silver, and 180 would be BROWN grey black black. The grey/silver band has a sheen to it that differs from the pigment bands so is probably metallic silver rather than grey. Perhaps this color-balanced zoomed in view of it will help.
180?
@KungFuJosh can you please set the scope to 500 Msa/s, low waveform acquisition rate (to make the TinySA's glitches less visible), low persistence, and record a video of a 30 seconds long frequency sweep from, say, 110 MHz to 270 MHz?
Coax connection with a 50 Ohm feed-through terminator, if possible, to make the test conditions the same as in my test.
It will be interesting to see at what frequencies (and at what ratio relative to the sampling rate) it will become first wobbly and then AM-like (if it will), to compare that to Rigol.
