Individual Channel Trigger for multiples channels in PXIe-6378

Hello Every one,

Our requirement is to acquire multiple channels data from different Sensors.So we require different threshold for each channel /Sensor,when ever threshold crosses for individual channel then only the specific analog input channel should be acquired along with pretrigger samples.

So i need to use multiple triggers for multiple channels with pre trigger samples

Kindly help on this requirment whether it can be possible with NI PXIe-6378

No, the device does not have that capability.  Here's what you'll need to do instead:

 

1. Acquire all channels continuously, retain enough past data for your pretrigger samples.

2. Check for triggering conditions by processing the data in software.

3. Keep the channels that show triggering conditions, ignore the others.

(4. Profit!!!)
