Measurement nam e Definition
Fall Time
Time that th e falling edge of the first pulse in the
waveform takes to fall from 90% to 10% of its amplitude.
Positive Duty
Cycle
Measurement of the first cycle in the waveform.
Positive Duty Cycle = Positive Wid th/Period × 100%
Negative Duty
Cycle
Measurement of the first cycle in the waveform.
Negative Duty Cycle = Negative Width/Period × 100%
Positive Pulse
Width
Measurement of the first positive pulse in the waveform;
time between t he 50% amplitude points.
Negative
Pulse Width
Measurement of t
he first negative pulse in the waveform;
time between th
e 50% amplitude points.
Burst Width
The duration of a burst. Measured over the entire
waveform.
Phase
Timing measurement. The amount one waveform leads
or lags another in time. Expressed in degrees, where
360° comprise one waveform cycle.
Positive
Overshoot
Measured over the entire waveform.
Positive Overshoot = (Max-High)/Amplitude × 100 %
Negative
Overshoot
Measured over the entire waveform.
Negative Overshoot = (Low-Min)/Amplitude × 100%
P
k-Pk
Measured over the entire waveform.
Peak-to-peak = Max - M in
Amplitude
Measured over the entire waveform.
Amplitude = High (100%) - Low (0%)
High
The value used as 100%. Calculated using either the
min/max or the histogram method. Measured over the
entire w avefor m .
Low
The v alue used as 0%. Calculated using either the
min/max or the histogram method. Measured over the
entire w avefor m .
Max The maximum amplitude. The most positive peak voltage
measured over the entire waveform.
Min The minimum amplitude. The most negative peak
voltage measu red over the entire waveform.
