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.
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.
Delay
Delay measures the time difference from the selected edge on source 1 and the
selected edge on source 2 closest to the timebase reference point at the middle
threshold points on the waveforms. Negative delay values indicate that the
selected edge of source 1 occurred after the selected edge of source 2.
