I am using two DAQ (USB1808 and QUAD08) to measure analog input and encoders respectively. The two DAQs are sync with the clock-input with USB1808 as Master and QUAD08 as Slave. At the beginning of the run, both encoder signal (blue line) and analog signal (red line) are sync (can observed in the image attached "Before Drift.png"). However, after run for about 5 minutes, the analog signal drift to the left ("After Drift.png"). Is there any way to avoid this or overcome this drift offset?
