Behavior. The trigger level markers indicate the voltage level where the trigger or threshold levels of the active waveform occur:
â–
The Short trigger level marker displays a short arrow on the side of the graticule by the active waveform.
â–
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 eye crossing measured at the MidRef as a percent of the eye
period.
DCD(sec) = 100% × TDCDp-p/(TCross2mean – TCross1mean)
