I acquired a new board for our SCXI chassis. T

Question

he new board is SCXI-1531. I found a library VI which allows me to look at one channel at a time. Is there an example VI available on the SCXI-1531 to acquire up to 8 channels input simultaneously? I would eventually like to vary the number of channels.

he new board is SCXI-1531. I found a library VI which allows me to look at one channel at a time. Is there an example VI available on the SCXI-1531 to acquire up to 8 channels input simultaneously? I would eventually like to vary the number of channels.The example titled SCXI-1531 Frequency.vi is a good example that allows measurement and processing of a variable number of channels. To read more than one channel, modify the last section of the SCXI string to "0:2" to read channels 0 through 2 for example. Or use 1, 4 to read channels one and four.
If you are new to SCXI strings, check out this KB entry: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/6fc83b7ac9aca5788625615b00823d65?OpenDocument
Also, to make the vi more flexible for different numbers of channels, use For Loops with auto indexing enabled. Then you can process each channel's data separately without needing to know the exact number of channels beforehand. This is also demonstrated in the attached example.
