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 required for the l eading edge of the first pulse in the waveform or gated region
to rise from the low reference value (default = 10%) to the high reference value (default =
90%) of th
e final value.
Fall Time
The time r
equired for the falling edge of the first pulse in the w aveform or gated region to
fall from the high reference value (default = 90%) to the low reference v alue (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 cy
cle is measured on the first cycle in the waveform or gated region.
Negative Duty
Cycle
The ratio of the negative 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.
Positive Pulse
Width
The distance (time) between the m id reference (default 50%) amplitude points of a
positive pulse. The measurement is made on the first pulse in the waveform or gated
region.
Negative Pulse
Width
The distance (time) between the m id reference (default 50%) amplitude points of a
negative pulse. The measurement is made on the first pulse in the waveform or gated
region.
Burst Width
The duration of a burst (a series of transient events) and is measured over the entire
waveform or gated region.
Phase
The amount of time that one waveform leads or lags another waveform, expressed in
degrees where 360° makes up one waveform cycle. See also Delay.
