Triggering Problems

[TimUIUC]

I'm trying to use a trigger to collect only a small portion of data at a high scan rate on my PCI-6036E card. Does anyone have a sample VI that has this already implimented? I'm trying to use an impact hammer to do the modal analysis on my test apparatus, and I need to collect two channels for accelerometers.  Any help would be appreciated.

hi there

see Help->Find Examples and browse (see attachment). unfortunately you can only use digital triggers (TTL level 0V/5V) with 6036. You'll need other hardware if you want to use an analog trigger.

So it wouldn't be possible to trigger off of one of my analog input channels then???

would I be able to do it with a 6110, cause we also have one of those laying around?

Also, I'm using Labview 6i too....

Hi TimUIUC,

That's correct, the PCI-6036E can only do digital triggering, so you would not be able to trigger off of an analog input channel.  The PCI-6110, on the other hand, does support analog triggering, so you could do that. 

This information is listed on the Data Sheets for these cards, which are linked to from the product pages.  For example, go to ni.com and type 6110 in the search box on the top of the page.  There will be a link to "NI PCI-6110".  This is the product page for that card, and from there you should see a link to "Data Sheet" right under the product description.  There is a chart on the first page of the Data Sheet which summarizes the hardware capabilities of the device.  You will see that under "Triggers" it lists both Analog and Digital. 

Once again, use the Example Finder to find examples of analog input using an analog trigger.  I hope this information helps!

Best regards,
