Using the Oscilloscope
The Scope Marker Menu
The Marker Value display consists of two blocks. One contains settings
for the voltage markers, the second contains settings for the time
markers. If only one set of markers is turned on, only one of the two
blocks will appear on the screen.
On the marker menu, if time markers are turned off, the Sample Period
display will appear on the marker menu. If time markers are selected as
either On or Auto, the Sample Period display is not visible on the
Marker menu.
The Display Options field never appears on the Marker menu.
