Time Measurements
Time measurements include 9 kinds of time parameter measurements.
1. Period: Defined as the time between the middle threshold points of two consecutive,
like-polarity edges.
2. Frequency: Defined as the reciprocal of period.
3. + Width: The time difference between the 50% threshold of a rising edge to the 50%
threshold of the next falling edge of the pulse.
4. -Width: The time difference between the 50% threshold of a falling edge to the 50%
threshold of the next rising edge of the pulse.
5. Rise Time: The time for the signal amplitude to rise from 10% to 90%.
6. Fall Time: The time for the signal amplitude to fall from 90% to 10%.
7. BWid: The duration of a burst over the entire waveform.
8. + Duty: The ratio of the positive pulse width to the period.
9. -Duty: The ratio of the negative pulse width to the period.
10. Delay:Time from the trigger to the first transition at the 50% crossing.
11. T@M:Time from trigger of each transition at a specific level and slope.
