Clock Timing

This section describes how clocking for the digital data is provided. Clock timing information and diagrams are supplied for the different port configurations (serial, parallel, or parallel interleaved data transmission) and phase and skew settings. All settings for the interface module are available on the signal generator user interface (UI).

Clock and Sample Rates

A sample is a group of bits where the size of the sample is set using the Word Size softkey. The clock is the signal that tells when the bits of a sample are valid (in a non- transition state). The clock and sample rates are displayed in the first- level and data setup softkey menus. The clock rate and sample rate are usually the same. They will differ when serial mode is selected, or when there are multiple clocks per sample.
