Analog Discovery 2 AWG Pulse Jitter

[Tobi]

Hello,

I use the Analog Discovery to trigger the beginning and duration of an experiment. Therefore, timing is pretty critical. When I set the frequency of the "pulse" wave form to 10.33Hz with a duty cycle of 0.05% (=pulse width of 48.4us) I see some sort of jitter (see attached video). The amount of jitter seems to depend on the frequency, i.e. increasing the frequency leads to less jitter at an equal pulse width. My question is: Has anyone else noticed this and is there anything I can do to prevent/reduce the jitter or have I simply reached the limit of the instrument? 

Thanks for your help!

Hi @Tobi

Please select "Auto sync".
The limited run will force the signal to restart from phase zero for each period.

With continuous run the signal might generated at different samples phases in each period. This is useful for signals except for square.
