functions to verify the trigger and channel settings

Post by kanth_tvs »

Hello,

Can some one point to me whether there are functions within ps4000.dll which allow me to verify whether the picoscope has accepted the settings for trigger and the channels, after they are set.

I do look at the status given by the corresponding set functions, but I would also like to double check the settings by reading them from the scope.

I am using a Pico 4424 scope.

Hi

There aren't any functions to check the settings. All you need to do is check the the returned status code is PICO_OK (0). If any values are out of range or there are any other problems, the status code will be non-zero

Hi
I was recently trying to do exactly the same thing (but eventually decided to rely on pico_status)

However- the ps4000 manual (page37) does mention a command called "ps4000IsTriggerOrPulseWidthQualifierEnabled"
I tried this, but 'triggerEnabled' always returned as zero, regardless of whether or not the trigger successfully fired a few lines later.

Personally, I dont actually need this line of code any more, but it could be useful to know if this command works- or at least does what it implies it should do!

Hi

The value of triggerEnabled enabled appears to not be changed by the dirver.

I have submitted a bug report.

Thanks
