Hey,
Does the picoscope have something called trigger holdoff and how would I go about doing it in Labview.
Without the trigger holdoff the signal that I measure has a lot of jitter and is hard to get any measurements out of it.
Trigger hold off
Re: Trigger hold off
Picoscopes do not have a trigger holdoff feature.
What is the exact nature of the signal, it may be possible to set up an advanced trigger that will perform a similar function to holdoff. If you post a psdata file, File->SaveCurrentWaveform, we can take a look.

Re: Trigger hold off
Hey,
Attached,
This is pulsed operation since it exaggerates the problem,
On the picoscope software I can get it to be stable but not in labview whatever trigger type or levels I use.
Also the trigger levels should be as low as possible since this wave form will be changing(the amplitude and possibly the duty ration, not the frequency)

Re: Trigger hold off
It should be possible to trigger in Labview with this signal, it looks clean enough, and as you say Picoscope 6 copes with a simple rising edge trigger.
Your issue may be that you need to add some hysteresis when you set the trigger, we use 2560 in our console examples.
