The hardware counter uses the trigger comparator output. Therefore, the
counted channel's trigger level (or threshold for digital channels) must be
set correctly. The Y cursor shows the threshold level used in the
measurement.
Analog and digital channels can be selected as the source.
Only one Counter measurement can be displayed at a time.
+ 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.
