How to read HWS file into DAQ 6259

[jks55]

Hi,

Im new to LabvIew.  I have used the Arbitrary Waveform Generator software to create a HWS file that i would like to output on a channel of the 6259 DAQ.  I dont see any utilities that would allow me to do this (read in from a file).

Also, does the DAQ store the data (channel, value and time) somewhere so that it can be executed real time when a trigger is received?

thanks

Greetings JKS,

To perform this operation, all you need to do is use the niHWS Retrieve Waveform.vi and wire its output to a DAQmx Write.vi.  The HWS VI's are contained in non-DAQmx drivers, however, so you will need to download the NI-SCOPE, NI-FGEN, or NI-HSDIO drivers to obtain the HWS VI's. 

To answer your second question, you can save the data obtained from a DAQmx Read.vi to a file for future access.  Take a look at our File I/O examples in the NI Example Finder for templates.

Thank you for choosing National Instruments, and I wish you the best of luck with your future LabVIEW programming.  Feel free to reply with any additional questions...
