how to generate 2 rectangular signals with pxi 6221

[J3n5]

Hi everyone,

 following problem. I try to generate two rectangular signals with adjustable frequencies. The first one is working fine, but when creating the second signal, I get following error:

DAQmx Write (Digital 1D U8 1Chan NSamp).vi:2410002<append>

<B>Property: </B>SampClk.Src

<B>Property: </B>SampClk.ActiveEdge

<B>Source Device: </B>Dev6

<B>Source Terminal: </B>Ctr1InternalOutput

<B>Required Resources in Use by</B>

<B>Task Name: </B>_unnamedTask<1>

<B>Source Device: </B>Dev6

<B>Source Terminal: </B>Ctr0InternalOutput

<B>Destination Device: </B>Dev6

<B>Destination Terminal: </B>do/SampleClock

<B>Task Name: </B>_unnamedTask<3>

How can I fix this problem? Or do you have other ideas to realize this example?

VI is included.

Kind regards

Hi everyone,

I found my solution. I used two counters to create those pulse signals and to adjust the frequency.

Here is my solution, it works fine for me.
