Solution
When using Synchronizing PXI-CAN with DAQmx Analog Input (using PXI-CLK10).vi, the default for the reference clock for the DAQmx timing is PXI_Clk10, which is the 10 MHz clock. Since the X-Series cards do not support synchronization to the 10 MHz clock, this is the source of error. When using this example with an X-Series Card, change the reference clock to PXI_Clk100, which is the 100 MHz clock. This clock is supported for synchronization for X-Series Cards, and is synchronized to PXI_Clk10.
The value to be changed can be seen in the image below. The example referenced can be found below under attachments.
