Front-Panel Reference
When the Type markers field is selected, it will toggle between Percent
and Absolute.
The Percent type setting is for levels that are a percentage of the
top-to-base voltage value of a waveform. The top-to-base voltage value
of a square wave is typically not the same as the peak-to-peak value.
The oscilloscope determines the top and base voltages by finding the
flattest portions of the top and bottom of the waveform. See figure
25-14. The top and base values do not typically include preshoot or
overshoot of the waveform. The peak-to-peak voltage is the difference
between the minimum and maximum voltage found on the waveform.
The Absolute type allows you to set an exact voltage level to the X or
0 marker.

X-Marker set
on
O-Marker set on
The X-O Marker set on - field assigns an input waveform (CHl or
CH2) to the X or 0 marker. When you select this field, the field will
toggle between the waveform sources.
The default selection for the Marker set on- field is CHl.
