PXIe-5745 AWG Question

Hello,

 

I am using a PXIe-5745 AWG and am just trying to get it to output a 20kHz sine wave.  I am new to programming in LabVIEW FPGA and have not used a FlexRIO device before.  I used the Help and an example project was automatically generated for me, which I have attached.  I am using "Basic.vi" as the host VI.

 

When I try to change the frequency (on the Basic.vi front panel) of the AO to 20kHz, the signal generated is still in the Mega hertz range.  I tried to just add a loop timer to the FPGA loop (so that I can change the frequency) that outputs the waveform but it is a single cycle timed loop and that isn't allowed.  I also tried adjusting the sample rate and # of samples but that still did not work.

 

I tried reading through the FlexRIO documentation but I am still not clear on how the FLEXRIO triggering and Stream Vis work conceptually.

 

Hopefully this is something simple.  My ultimate goal is to simply have  UI that I can use to output a 20kHz sine wave and be able to change the amplitude and frequency.

 

Any help is appreciated!
