BIPHASIC square wave pulse trains?

[IMPLANT GUY]

    For stimulation of nerves I need to generate biphasic square wave pulse trains, i.e., trains with no net charge over the period of each cycle.  I would like to be able vary the phase duration and the pulse frequency independently. I could do this in LabView v.2, but I cant find any way to do it in my new v.8 software.

Hi IMPLANT GUY,

Thank you for posting to the NI forums.  Could you give us some more information about your data acquisition (DAQ) device?  What type of device is it, and which driver are you using for it?  There shouldn’t be any functionality in LabVIEW 2 that there isn’t in LabVIEW 8.0. 

Post back with some more info, and we’d be glad to point you in the right direction for your DAQ needs.  Thanks!
