How can I get a square wave with a duty cycle of 50% and 0 to 5 volts?

[wana be prog]

I have a new PXI-6723 DAQ card.  I need to produce a 50% duty cycle, 0 to 5 volt,  square wave.  I have tried the examples and found a one that puts out a sqare wave but it dips below the 0 volt range, and has no DC off set to counter act this.  It is very important for the wave to NOT go negative.  Thanks, Fred

Hi Fred,

         The best way to make a square wave from 0-5 volts is to use one of your counters. I attached a picture where this done rather simply through LabVIEW, will this work for you?
