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 marker type in the Markers dialog box that appears.
• To turn on Marker A, press the Position key 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 key 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.
