Trigger Delay on Picoscope 2206B

Post by m.a.t »

Hi, using a Picoscope 2206B in Matlab, I want to output a waveform at 25ms delay after an input trigger. I've been working with the Example files in the 2000 Series A API, and I can generate my waveform with AWG when the trigger arrives, but I have not worked out how to introduce a trigger delay.

The trigger and AWG are defined as follows

% Trigger
triggerGroupObj = get(ps2000aDeviceObj, 'Trigger');
triggerGroupObj = triggerGroupObj(1);

set(triggerGroupObj, 'autoTriggerMs', 0);
[status.setSimpleTrigger] = invoke(triggerGroupObj, 'setSimpleTrigger', 1, 80, 2);

% AWG output
[status.setSigGenArbitrary] = invoke(sigGenGroupObj, 'setSigGenArbitrary', 10, 2, y, 0, 0, 0, 200, 0, 0, 1, 0);




I have tried "set(triggerGroupObj, 'delay',1e5)", and while the delay property appears to be updated, the output stays exactly when the trigger is input. Is there another way to set up the triggering that will work for the delay?

Thanks

Hi

Where in the code are you updating the delay value in relation to the setSimpleTrigger function?
