Using Markers
Use the Markers controls to display and adjust 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 the values
are highly accurate.
Using the markers controls, you can control multiple sets of markers within the
oscilloscope grid.
Both time and voltage differences between the markers are updated continuously
on the screen. By default, the markers track the source waveform. Voltage
measurements from the markers are the value of the waveform at the time set with
the marker arrow keys.
• To add a marker, press the [Markers] key or choose Measure/Mark > Add Markers...
or click the Markers button ; then, select the sources and mode.
Notice the drawing in the Mode area of the Marker dialog box.
• To select one of the markers, push one of the marker Position knobs. Turn the
knob to move the marker. Push the knob again to select the next marker.
• Marker 1 has a solid line pattern on the waveform display. It is associated with
the first available source on the display.
• You can drag a marker to quickly move to the position you want on the
waveform.
• You can use the front panel Position knob for fine adjustment, or use the Add
Marker dialog box to set the marker position precisely.
