Time measurements (cont.)
Measurement Description
Fall Time
The time required for the falling edge of the first pulse in the w aveform or gated region to
fall from the high reference value to the low reference value of the final value.
DelayRR
The time between the mid reference (default 50%) amplitude point of the r ising edge of
two differe
nt waveforms. See also Phase.
This measurement requires inputs from two channels.
DelayRF
The time between the mid reference (default 50%) amplitude point of the r ising edge of
one waveform and the falling edge of a second waveforms. See also Phase.
This measu
rement requires inputs from two channels.
DelayFR
Thetimeb
etween the m id reference (default 50%) amplitude point of the falling edge of
one waveform and the rising edge of a second waveforms. See also Phase.
This measurement requires inputs from two channels.
DelayFF
The time between the mid reference (default 50%) amplitude point of the falling edge of
one wave
form and the falling edge of a second waveforms. See also Phase.
This measurement requires inputs from two channels.
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(RR, RF, FR, FF).
This m
easurement requires inputs from two channels.
+Width
Posit
ive pulse width. The distance (time) between the mid reference (default 50%)
amplitude points of a positive pulse. The measurement is made on the first pulse in
the waveform or gated region.
–Width
Negative pulse width. The distance (time) between the mid reference (default 50%)
ampl
itude points of a negative pulse. The measurement is made on the first pulse in
the waveform or gated region.
+Du
ty
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.
–Duty
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.
Burst Width
The duration of a burst (a series of transient events) and is measured over the entire
waveform or gated region.
