Time Parameters
1. Period: the time between the threshold middle value of one edge to the
threshold middle value of the next edge with the same polarity.
2. Freq: frequency; 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 of the rising edge.
4. Fall Time: the time for the signal amplitude to fall from the threshold upper
limit to the threshold lower limit of the falling edge.
5. + Width: positive pulse width; the time between the threshold middle value of
a rising edge to the threshold middle value of the next falling edge.
6. - Width: negative pulse width; the time between the threshold middle value of
a falling edge to the threshold middle value of the next rising edge.
7. + Duty: positive duty cycle; the ratio of the positive pulse width (+ Width) to
the period.
8. - Duty: negative duty cycle; the ratio of the negative pulse width (- Width) to
the period.
Note: In the figure above, the default values of the threshold upper limit, threshold
middle value and threshold lower limit are 90%, 50% and 10% respectively. You can
also set them via Measure  Setting  Type  “Threshold”. For the setting
method, refer to “To Set the Threshold”.
