Specifications are valid under the following conditions:

  • All modules are installed in one PXI Express chassis.
  • The NI-TClk driver is used to align the Sample clocks of each module.
  • All parameters are set to identical values for each SMC-based module.
  • Modules are synchronized without using an external Sample clock.
  • Self-calibration is completed.
Note Although you can use NI-TClk to synchronize non-identical SMC-based modules, these specifications apply only to synchronizing identical modules.
