Time Measurements
Time measurements include 9 kinds of time parameter measurements.
Figure 68 Time Measurements
1. Period: Period for every cycle in a waveform at the 50% level, using positive slope.
2. Frequency: Frequency for every cycle in a waveform at the 50% level, using positive
Slope.
3. + Width: Width measured at 50% level and positive slope.
4. - Width: Width measured at 50% level and negative slope.
16. Rise Time: Duration of rising edge from 10-90%.
5. Fall Time: Duration of falling edge from 90-10%.
6. BWid : Time from the first rising edge to the last falling edge, or the first falling edge to
the last rising edge at the 50% crossing.
7. + Duty: Ratio of positive width to period.
8. - Duty: Ratio of negative width to period.
9. Delay
：
Time from the trigger to the first transition at the 50% crossing.
10. T@L
：
Time from trigger of each transition at a specific level and slope, include:
Current, Max, Min, Mean, Std-dev.
