14 Measurements
 
+ 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.
Burst Width
The Burst Width measurement is the time from the first edge to the last 
edge on screen.
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.
