Text TERM DEFINITION
Width
Pulse Width The interval between the first and second signal crossings of the mesial line.
Rise
Risetime The interval between the first signal crossing of the proximal line to the first
signal crossing of the distal line.
Fall Falltime The interval between the last signal crossing of the distal line to the last signal
crossing of the proximal line.
Period Pulse Period The interval between two successive pulses. (Reciprocal of the Pulse Repetition
Frequency)
PRFreq Pulse Repetition The number of cycles of a repetitive signal that take place in one second.
Frequency
Duty C
Duty Cycle The ratio of the pulse on-time to off-time.
Offtime
Off-time The time a repetitive pulse is off. (Equal to the pulse period minus the pulse
width).
Peak Peak Power The maximum power level of the captured waveform.
Pulse
Pulse Power The average power level across the pulse width, defined by the intersection of
the pulse rising and falling edges with the mesial line.
Oversh Overshoot A distortion following a major transition. (The difference between the maximum
amplitude of the overshoot and the top line).
Avg Average Power The equivalent heating effect of a signal.
IEEETop
Top Amplitude The amplitude of the top line. (See IEEE definitions)
IEEEBot
Bottom Amplitude The amplitude of the base line. (See IEEE definitions)
Skew
Skew The time between the mesial level of a pulse on Channel 1 and a pulse on
Channel 2. The pulse can be the power or trigger signal.
EdgeDly
Edge Delay The time between the left edge of the display and the first mesial transition
level of either slope on the waveform.
