Measurements.)
Time Measurements
Measurement Description
Period
The time required to complete the first cycle in a waveform or gated region. Period is the
reciprocal of frequency and is measured in seconds.
Frequency
The first cycle in a waveform or gated region. Frequency is the reciprocal of the period; it is
measured in hertz (Hz) where one Hz is one cycle per second.
Delay
The time between the mid reference (default 50%) amplitude point of two different waveforms.
See also Phase.
Rise Time
The time require d for the lead ing edge of the first pu lse in the waveform or gated region
to rise from the low reference value (default = 10%) to the high referen ce value (d efault
= 90%) of the final value.
Fall Time
The time required for the falling edg e of the first pulse in the waveform or gated region to fall
from the high reference value (default = 90%) to the low ref erence value (default = 10%) of
the final value.
Positive Duty
Cycle
The ratio of the positive pulse width to the signal period expressed as a percentage. The duty
cycle is measured on the first cycle in the waveform or gated region.
