I insist that with lower frequency (everything else being equal) the voltage at the filter capacitor falls further. Model an AC voltage source, followed by a rectifier bridge, a capacitor and a constant current load. My prediction is that the voltage at the capacitor and load falls further with decreasing frequency. It must be obvious to anyone.
I meant I get a clean sine wave up to 841MHz.Ah, I see. Well, that's just one point in time, and the display persistence hides the deviation of the peaks from the real value. What we're interested in is observing dynamically how the waveform becomes wobbly as the signal frequency increases and gets closer to that point.
It's clearly better than the Rigol, though, which is much worse at 1/2.5x the sampling rate. I wonder how the SDS800X HD scopes perform in this scenario.
Here's, BTW, a 500 MHz sine wave captured at 1.25 GSa/s sampling rate:
I keep wondering what that 1N4148 is even doing there? It's the oddest circuit I've seen.
