Select the desired Gate Time. The data displays shown at the lower portion of the dialog provide

the status and the frequency in hertz.

FIGURE 3.7 UDAS SYSCHECK Counter Test: Measure Frequency Mode

The gate time is the amount of time that UDAS uses to count TTL transitions. This time base

allows frequency to be calculated by the software.

Longer gate times result in frequency calculations with more significant digits because a greater

number of transitions are gathered. Shorter gate times result in frequency calculations with

fewer significant digits because a smaller number of transitions are gathered.
