So I'm writing an application base on the NI scope 2014 instrument design libraries. I'm trying to simply replace the integer decimator that is used in the design with a fractional decimator from the palette. The design seems to work running in simulation mode, with values being streamed to the PC host. However when I try it on the physical hardware (5170R) the acquisition times out. This happens even if I give it an extremely long timeout- basically no samples appear at the PC end.
I suspect that the problem may have something to do with the fact that the decimator requires a x3 clock. After creating a x3 clock in project explorer (it's a pre-existing option from the new clock menu), when I look at the clock properties, there is a warning that LabVIEW will not generate a clock period constraint for this clock, which must be defined in a CLIP file. I assumed it would be OK as it is derived from a pre-existing x1 clock in the project (which also has the same warning but presumably 'works' as it's used for the sample loop).
Any ideas?
