To use the markers
Markers make it easier to make precise measurements because the marker
measurement readouts show exact voltage and time positions for the markers.
The measurements are based on actual waveform data from the acquisition
system, not on approximations based on the display position, so you can be
sure that the values are highly accurate.
• To select the type of marker mode that you want to use, press the [Markers]
key and select the mode in the Markers Setup dialog box that appears.
• To turn on Marker A, press the Position knob until the marker that you want
to move appears in the pop-up dialog box.
Marker A has a solid line pattern on the waveform display. It is associated with
the first available source on the display.
• To turn on Marker B, press the Position knob until the marker that you want
to move appears in the pop-up dialog box.
Marker B has a dashed line pattern on the waveform display. It is associated
with the first available source on the display.
• To move a marker, turn the Position knob. In Measurement Marker mode, the
marker position cannot be changed.
