Good afternoon ndaugherty and devchander,
Thanks for contacting National Instruments with your issue, we'll try and resolve it for you as quickly and efficiently as possible.
devchander is correct, it is possible to program National Instruments Scopes (in this case the 5122) using DAQmx, however it is not recommended and not supported. DAQmx is a multi-purpose driver designed, whereas the NI-SCOPE API is designed specifically for out Modular Instrument Scope cards. For this reason, a lot of the functionality, timing considerations and register access, will be exceedingly difficult to control via DAQmx compared to NI-SCOPE.
The NI-SCOPE driver is a free download available to all of our customers and can be located here.
Best of luck with your project.
Sincerely,
Minh Tran
