Need to gen 2 square waves of varing freq on 2 different channels at the same time

[Chris_Young]

Need to have 2 AO channels that can produce a square wave on each one indepd of each other. The freq has to ramp up to a defined point on each channel. I am trying to create a vi that will control 2 translators that will drive a two axis radio antenna. I have an E-DAQ and LabVIEW 5.0

[NI support]

Chris,

I am attaching an example that does exactly that for sine waves. You can replace the sine pattern VI with
the Pulse pattern VI included with the Full Development system:

From the functions pallette
Analyze >> Signal Processing>>Signal Generation

Hope this helps.

Thanks for contacting National Instruments

Example Program Document
-------------------------------------------------------
Title: Continuous Analog sine Output on multiple (two) channels with different frequencies
Description: This example is a modification of a continuous analog output example that ships with LabVIEW so that output can be done simultaneously on both analog output channels of an e-series type board
. Specifically, this program generates sine waves of different, user-specified frequencies on each channel.
