National Instruments TClk synchronization method and the NI-TClk driver 
are used to align the sample clocks on any number of SMC-based modules 
in a chassis. For more information about TClk synchronization, refer to the 
NI-TClk Synchronization Help, which is located within the NI High-Speed 
Digitizers Help.

•

Specifications are valid for any number of modules installed in one 
NI PXI-1042 chassis.

•

All parameters set to identical values for each SMC-based module.

•

Sample Clock set to

 

250 MS/s and all filters are disabled.
