Generate Quadrature signals with NI-6602

[Co]

Hi,

We are currently trying to generate a  "A,B quadrature signal" with a number of set pulses.

We use LabwindowsCVI to create the code for this used on a NI-6602.

How can we create a stable signal using DAQmx with exactly +/-90 degree phase shift?

Kind regardes, Mo & Co

Hi,

You have to start two counter tasks. One of them should have an initial delay.

Here are some links.

Thanks bas,

Thats what we did, use two tasks and start them with the same trigger.
