Steve J, Did you ever get a proper response from this posting? Did you ever get your LV program to work? I have a similar program to write in that it is also to use Peter's board.
email email@example.com if you can

Hi, I'm not sure whether this is the right place for asking this question or not and if not, then please guide me to the right place for asking such question. Thanks.
I have a stepper motor with the Vector Network Analyzer Anritsu MS4623B. I got it up and running with the LabWindows/CVI. I need to sync the motion of the stepper motor with my data acquisition. Basically, I have to acquire the data in a way that in the start the motor will come back to home position wherever it was and then I want to move it to the specific position to do the measurements (For Example, I want to measure the 40 GHz channel between 1m to 3m movement of a stepper motor on a linear positioning system (ball-screw)). I've interfaced the VNA with the PC using LabWindows/CVI and I've controlled the clockwise and anti-clockwise movements of the stepper motor using LabWindows/CVI but I'm unable to sync the system in a way that whenever I run the code, the motor will run back to the home position and then move to a specific measurement start position and move till the end position and in between do the increment and stop and acquire the data. Is there any one to help me please? It's really urgent please and I'm doing this thing first time so please guide me in a proper way. I shall really apprecaite that and will be highly obliged with you. Thanks for your time and concern.
Thanks and Regards.

I see that you have multiple posts regarding the same issue. Please continue the discussion in your new thread here: http://forums.ni.com/t5/LabWindows-CVI/Controlling

This thread is pretty old, so I would recommend making a new thread on our motion control forum so that people in the community reply: http://forums.ni.com/t5/Motion-Control-and-Motor-D
I would also specify what hardware you actually have (controller, drive, etc.), or if you are looking to purchase hardware; knowing whether you are using NI-Motion or NI SoftMotion would be useful information as well - and if you already have the hardware and drivers, there are a lot of good examples in the Example Finder in LabVIEW (Help>>Find Examples). What version of LabVIEW are you using? There are many different considerations when troubleshooting a motion system, so as much information as you can provide would be helpful for us to help you get started!
