Hardware

  • PXIe-4497
  • PXIe-4303

Issue Details

I need to sync my NI 4497 and my NI 4303, but I cannot channel expand or use the reference clock sync example out of the box.

Solution

1. Start from the Analog Input - Synchronization example and use the DSA Reference Clock Sync
2. Remove the Filter Delay from both devices
3. Re-sample the slave waveform to align the samplesĀ 

Additional Information

Before the re-sampling, the devices are synchronized to the same start time. The different chip architectures with the signal conditioning and DSA devices will cause them to run at slightly different rates, causing the appearance of drift over long periods of time
