Width; Duty Cycle; Rise Time; Fall Time - Agilent Technologies InfiniiVision 2000 X-Series User Manual

+ Width

+ Width is the time from the middle threshold of the rising edge to the
middle threshold of the next falling edge. The X cursors show the pulse
being measured. The Y cursor shows the middle threshold point.
– Width
– Width is the time from the middle threshold of the falling edge to the
middle threshold of the next rising edge. The X cursors show the pulse
being measured. The Y cursor shows the middle threshold point.

Duty Cycle

The duty cycle of a repetitive pulse train is the ratio of the positive pulse
width to the period, expressed as a percentage. The X cursors show the
time period being measured. The Y cursor shows the middle threshold
point.
Duty cycle = + Width

Rise Time

The rise time of a signal is the time difference between the crossing of the
lower threshold and the crossing of the upper threshold for a
positive- going edge. The X cursor shows the edge being measured. For
maximum measurement accuracy, set the horizontal time/div as fast as
possible while leaving the complete rising edge of the waveform on the
display. The Y cursors show the lower and upper threshold points.

Fall Time

The fall time of a signal is the time difference between the crossing of the
upper threshold and the crossing of the lower threshold for a
negative- going edge. The X cursor shows the edge being measured. For
maximum measurement accuracy, set the horizontal time/div as fast as
possible while leaving the complete falling edge of the waveform on the
display. The Y cursors show the lower and upper threshold points.
