1. Bring the IRIG-B signal on the PXI-668x PFI connector.
2. Set the PXI-668x time reference to either IRIG-B DC or IRIG-B AM depending on the IRIG-B signal.
- To do this, you can check the LabVIEW example "Set Time Reference.vi". Located in LabVIEW >> Help >> Find Examples >> Hardware Input and Output >> Timing and Synchronization >> Time-based >> Set Time Reference.vi
3. Route the PXI-668x onboard oscillator to the PXI-668x clock-out connector (this can be done either in the code with the "NI Sync Connect Clock Terminals" or in NI MAX):
4. Physically cable the clock-out connector to the chassis 10MHz IN port of the chassis
- This is chassis dependent. The chassis must have a 10MHz IN port. As most of the PXI-668x cards have hybrid PXI connectors, there is no way to route this signal internally through the chassis.
5. Set the modules you want to synchronize to use the 10MHz chassis backplane clock as a reference, using the corresponding function of their driver API.
