What is the easiest way to generate an analog square wave output?

[tlantz]

I am a new user to LabVIEW, and what I would like to do is create a 10Vdc output for about and hour, and then a 0Vdc output for about 5 minutes, and then repeat this whole process about 1000 times. I am assuming it would be easiest to do this by outputing a square wave, but I don't know how to accomplish this. If you have any suggestions they would be appreciated.
Thanks.

You basically have two choices, you can do it with an analog output, or you could use a dio bit to control an external switch.

What is this signal going to be driving, and how much drive capability is it going to need?

Mike,

Thanks for the help, I think I figured it out yesterday. But just in case, I need to have about 10Vpp square wave with a 5Vdc offset, so that I can turn on and off a power supply over about 1000 hours.
