Selecting Automatic Measurements
The following tables list each automatic measurement by category: time or amplitude. (See page 89, Taking Automatic
Measurements.)
Time Measurements
Measurement Description
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.
Period
The time required to complete the first cycle in a waveform or gated region. Period is
the recipro
cal of frequency and is measured in seconds.
Rise Time
The time required for the leading edge of the first pulse in the w aveform or gated region
to rise from the low reference value to the high reference value of the fi nal value.
Fall Time
The time required for the falling edge of the first pulse in the waveform or gated region to
fall from the high reference value to the low reference v alue of the final value.
Delay
The time between the mid reference (default 50%) amplitude point of two different
waveforms. See also Phase.
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.
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 fi rst pulse in the waveform or gated
region.
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 fi rst cycle in the waveform or gated region.
Negative Duty
Cycle
The ra
tio 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.
Burst Width
The duration of a burst (a series of transient events) and is measured over the entire
wave
form or gated region.
