Measurement
Description
Fall Time
The time required for the falling edge of the
fi
rst pulse in the waveform or gated region to
fall from the high reference value to the low reference value of the
fi
nal value.
DelayRR
The time between the mid reference (default 50%) amplitude point of the rising edge of
two different waveforms. See also
Phase
.
This measurement requires inputs from two channels.
DelayRF
The time between the mid reference (default 50%) amplitude point of the rising edge of
one waveform and the falling edge of a second waveforms. See also
Phase
.
This measurement requires inputs from two channels.
DelayFR
The time between the mid 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 waveform 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 measurement requires inputs from two channels.
+Width
Positive pulse width. The distance (time) between the mid reference (default 50%)
amplitude points of a positive pulse. The measurement is made on the
fi
rst pulse in
the waveform or gated region.
–Width
Negative pulse width. The distance (time) between the mid reference (default 50%)
amplitude points of a negative pulse. The measurement is made on the
fi
rst pulse in
the waveform or gated region.
+Duty
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.
–Duty
The ratio of the negative 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.
Burst Width
The duration of a burst (a series of transient events) and is measured over the entire
waveform or gated region.
