Clock Timing
Figure 10-1 Data Setup Menu for a Parallel Port Configuration
The N5102A module clock rate is set using the Clock Rate softkey and has a range of 1 kHz to
400 MHz. The sample rate is automatically calculated and has a range of 1 kHz to 200 MHz. These
ranges can be smaller depending on logic type, data parameters, and clock configuration.
Maximum Clock Rates
The N5102A module maximum clock rate is dependent on the logic and signal type. Table 10- 1 and
Table 10- 2 show the warranted rates and the maximum clock rates for the various logic and signal
types. Notice that LVDS in the output mode using an IF signal is the only logic type where the
warranted and maximum rates are the same.
