Time Parameters
Explanation: Please refer to the explanations in “Measurement Setting” to set
the threshold upper limit, threshold middle value and threshold lower limit and the
default values are 90%, 50% and 10% respectively.
1. Period: defined as the time between the threshold middle values of two
consecutive, like-polarity edges.
2. Frequency: 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 to 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 to 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 value corresponding to the waveform maximum value (Vmax).
10. tVmin: the time value corresponding to the waveform minimum value (Vmin).
