Aux trigger problems for PS6000SetSimpleTrigger

Post by Picoscope0815 » Wed Jan 18, 2017 10:02 am

Hi all,

I noticed some irregularities using the Picoscope6000ExampleBlock.vi with AUX triggering.
I used a block form trigger Signal with approx. 2.5V on the Picoscope 6404C, Labview 2013 64bit.
Observations:

-by triggering on channel B everything works fine! It can be triggered on the falling and on the rising edge without a problem.

-by using the AUX input channel, triggering works somethings. That means if the falling edge is chosen, 3 out of 4 times it already triggers on the rising signal. It doesn't matter if the tigger threshold is on 32500 adc (~1V) or 16000 or 8000.

-with the same hardware configeration using the Picoscope 6 software the aux trigger works fine!

How can that be? Is there maybe an error in the ps6000setsimpletrigger.dll? Someone has similar experience or advice?

Thanks alot for your help!

Hi,

We have had a recent fix for an AUX IO trigger issue - please e-mail support@picotech.com and we can provide you with an updated ps6000 driver.

Thanks,
