Hi,
I'd like to increase output voltage and have a square wave output using PXIe-4322, so I cascade connected 2 AO ports, and set the two ports with the same frequency. I tried 10V 1000Hz to each port, it is ok to have a 20V 1000Hz square wave. But when i tried 10V 900Hz to each port, it shows the attached waveform. I supposed there should be synchronization between these two ports, and, I have tried some synchronized examples, but it does not work. It seems there should be only one Start Task when configuring the 4322 hardware.
And Please check the attachment of VI , I suspected the mark which is the sample numbers of each channel
Thank you
