sync mode in Digital Discovery - providing a sample clock

[kevin vannorsdel]

Can you comment on the function    FDwfAnalogInTriggerPositionSet()    when using sync mode (where the trigger becomes a clock used for sampling data in)?

 

It seems based on the examples that perhaps this becomes a count of samples but it is not spelled out as such in the SDK reference manual.  I need to understand a little more about sync mode and this is the first step.

 

THANK YOU!

Hi @kevin vannorsdel

The Digital Discovery has not oscilloscope so  FDwfAnalogIn functions can be used with this device.
For Record with FDwfDigitalInTriggerPositionSet you specify how many samples to capture or 0 for unlimited streaming.

Sorry,  I copied in the wrong function and meant to ask about  FDwfDigitalInTriggerPositionSet() so thank you for anticipating and answering that.   :)

Where can we find documentation on the use of these functions in sync mode?   The SDK PDF doesn't seem to include much about it that I have found.   Is it just the example scripts that show how its used?   Thanks!!!

There is not much to explain about this. In sync mode the trigger detector is used as sampling conditioner.
