Oscilloscope Reference Duty cycle distortion
Behavior
The trigger level markers (see page 637) indicate the voltage level where the trigger or threshold levels of
the active waveform occur:
The Short trigger level marker displays a short arrow on the side of the graticule by the active
waveform.
The Long trigger level marker displays a horizontal line through the active waveform.
NOTE. The trigger level indicator does not appear on inactive waveforms, reference waveforms, or
fast acquisition signals.

Duty cycle distortion
Duty cycle distortion is the peak-to-peak time variation of the first e ye crossing measured at the MidRef as
ap
ercent of the eye period.
DCD(sec) = 100% × TDCDp-p/(TCross2mean – TCross1m ean)
