Off

Turns off all of the marker functions, and removes the markers and marker
values from the display.
The statistics measurement results share the same area of the screen as the
marker values. In cases where you turn on statistics, the measurement
marker positions hide the statistics measurement results. To see the
statistics results, set the markers to off.

Manual

There are two sets of manual markers that are placed in the graticule area of
the display. The X1 and X2 markers are two vertical lines that you can move
horizontally, and the Y1 and Y2 markers are two horizontal lines that you can
move vertically. They are called manual markers because you can place them
anywhere in the graticule area independent of the signal.
You can position the manual markers anywhere on the display, which allows
you to make custom measurements. As long as you do not press the
Autoscale key, the manual markers stay in the position where you placed
them which allows you to make accurate delay measurements without having
both markers on the display. Also, they are not tied to the waveform data;
they are just positions on the display. The position readout is based on the
scale factors of the srouce waveform.
X1, Y1 Source and X2, Y2 Source
You can set the marker sources as channels, functions, or memories. For
example, you could set the X1, Y1 source to a waveform memory, and the X2,
Y2 source to a function. The scale used to position each marker on the
display is based on the scale of the waveform source that the marker is tied
to. You can select a marker source that is turned off, which prevents the
markers from displaying on the screen. If you cannot see a marker on the
screen, check to see if the marker source is turned off. Also, when you are
placing markers on a waveform, make sure that the source is set to that
waveform.
