So, I have a several RFSigGen devices, all with IVI-C drivers, and need to do use with them in TestStand 2017. I have it working with DLL calls, but I found this post from waaayyyy back and for the sake of my own education, I kind of want to go down the rabbit hole and explore making custom IVI step types (knowing full well that I'll probably chicken out before I make useful progress). It references the source for the IVI step types being in the following directory: \Components\NI\StepTypes\IVISteps
The closest I can find is \TestStand 2017\Components\StepTypes\IVISteps which doesn't contain any source. I'm guessing I'm either a) looking in the wrong place, b) missed an option when installing, or c) the code no longer ships. Any chance someone could point me in the right direction?
