Time Parameters
Figure 6-3 Time Parameters
1. Period: defined as the time between the middle threshold points of two
consecutive, like-polarity edges.
2. Freq: defined as the reciprocal of period.
3. Rise Time: the time for the signal amplitude to rise from the threshold lower
limit to the threshold upper limit.
4. Fall Time: the time for the signal amplitude to fall from the threshold upper
limit to the threshold lower limit.
5. +Width: the time difference between the threshold middle value of a rising
edge and the threshold middle value of the next falling edge of the pulse.
6. -Width: the time difference between the threshold middle value of a falling
edge and the threshold middle value of the next rising edge of the pulse.
7. +Duty: the ratio of the positive pulse width to the period.
8. -Duty: the ratio of the negative pulse width to the period.
9. tVmax: the time corresponding to the waveform maximum value (Vmax).
10. tVmin: the time corresponding to the waveform minimum value (Vmin).
Note: The default values of the threshold upper limit, threshold middle value and
threshold lower limit are 90%, 50% and 10% respectively. You can set them via
Measure  Setting  Type  "Threshold" and for the setting method, please
refer to the introduction in "Threshold Measurement Setting".
