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 until the mode appears in the pop-up dialog box.
• 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.
