I have repetitive pulses which come every 80ms. The length of a pulse is approx. 2ms.
I would like to measure the jitter of the time difference from pulse to pulse.
I can do this by triggering to a pulse and set the scope to persitent mode. I then can see the jitter of the next pulse.
My challenge however is that I would like to see this jitter with as high a resolution as possible.
One possibility would be to set a low time/dev and then set the delay time to a high number so I can see the next pulse in the screen.
My problem however is that I can not set the delay time high enough. I have noticed that it's limited to 10x the time/dev (e.g. 1ms/dev limits the time delay to 10ms). Where does this delay limit come from? The memory of the scope?
I would like to set 250us/dev and then set the delay to 80ms.
I'm using the PicoScope 2205.
Is this a limitation of the 2205? Would a larger PicoScope help?
I hope you can help
