Synchronizing encoder data with voltage readings

[cterrill]

I'm trying to measure a voltage signal and in some way synchronize those readings with angular position from a stepper motor. I'm controlling the stepper motors with a PCI-7354 and collecting voltage data with a USB-6210 DAQ. My encoders are currently wired into a UMI-7774 for motion control. I've read a bit about taking input from a quadrature encoder in a counter terminal but this is all new to me. Is there some simple way in DAQ Assistant or something to ensure that my voltage and position data are being recorded on the same clock? I know there are some timing issues inherent to using USB and unless I'm mistaken, the PCI-7354 operates on a different clock than the DAQ does.

Any help would be much appreciated!

Hi cterrill,

I was able to find this document that gives some examples on how to synchronize motion controllers with DAQ devices. Take a look:

Hopefully this helps!
