I have a cDAQ-9178 with NI 9403 module. I would like to use this module to output a 5v square wave for an arbitrary amount of time. I have tried a few methods with the most recent being a program very similar to this example : https://decibel.ni.com/content/docs/DOC-25288 . The differences being I simply fed the write a Boolean true and had it in a timed loop.
Upon testing the program and monitoring the output with a BK 2553 I found that I would either get a single 2v spike or a ~1V_pp_max oscillation about the ground. I tried it on two different channels and received the same results. Please advise.
