How to write from multiple devices to the same output file

[jmeisser]

Hello, I'm currently trying to write analog input data from a USB-TC and a USB-1608G to the same output file (CSV). So far the only way I've been able to do this was by matching the USB-1608G's data rate to that of the USB-TC, which maxes out at 2 Hz. Unfortunately, I need a much higher sample rate for the USB-1608G, and I haven't been able to figure out a way to accomplish this. I've tried using the alignment module, but it seems to take the lowest common denominator, which is the 2 Hz. I don't necessarily mind either repeating the extraneous values for the TC or leaving the cells where it's not sampling blank if that's what it takes, but at this point I'm wondering whether or not that's even possible.

Thanks in advance.

Use the Signal Adaptation module set to Linear Interpolation. Connect the faster channel to input zero and it will adjust the slower USB-TC data stream to match it.

That worked, thanks. I'd tried using that module before, but I had the wrong frequency connected to input zero.
