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. 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: the time between the threshold middle value of a rising edge to the
threshold middle value of the next falling edge.
6. - Width: the time between the threshold middle value of a falling edge to the
threshold middle value of the next rising edge.
7. + Duty: the ratio of the positive pulse width to the period.
8. - Duty: the ratio of the negative pulse 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 MEAS ïƒ Setting ïƒ Type ïƒ "Threshold". For the setting method,
refer to "Measurement Setting".
