NI Elvis III: Pattern Generator in LabVIEW

[martynl]

I am trying to use the NI Elvis III toolkit within LabVIEW 2019 to control the pattern generator onboard the Elvis. I need to use the pattern generator to create a pulse output, but have been unable to get it to run correctly. Attached is my VI that I made to generate a PWM signal with what should be an 80% duty cycle at 1Hz, but nothing happens when I deploy the VI and press the Boolean switch to configure the device.

Am I missing something here? I have verified that the pattern generator works fine in Measurements Live, and I have been able to successfully program the function generator and oscilloscope on my Elvis using LabVIEW following a similar syntax (I also attached one of my VIs that successfully uses these instruments). What do I need to add/change to get the pattern generator to work correctly?

Many Thanks

Hi,

After setting the configuration of the device to default values when you set true to the logic Intialize VI , the output sources must be enabled .

Best Regards.

thank you.
