I have three raw data files I need to output on three individual channels of a 6713 card... I'm having no problem outputting a single channel, but I have a few questions about combining the three files and using the WFM_from_Disk in VisualC++ or Visual Basic. Would it be correct to assume the file should be structured with alternating samples from each of the three source files?
Also, the WFM_from_Disk function is choking when I set the numChans parameter to anything larger than one. I've tried many combinations of values for the chanVect array without success. The function usually returns a invaildValueError (-10003). There also seems to be some relation to file size, but I can't find a definite pattern... I've
tried file sizes anywhere from 6 bytes to 900000. Where do I look next? Is there a better way to output my data?
Thank you,
