Using the Oscilloscope
The Scope Marker Menu
Voltage Markers optionsWhen you select the V Markers field on the display, a pop-up menu
appears. When you select the On field in the pop-up to turn Voltage
Markers On, you can manually move the Va and Vb markers to make
voltage measurements.
When you select the On field in the V Markers menu, five new fields
appear to the right of the V Markers field: Va On, Va Volts, Vb On, Vb
Volts, and Va to Vb fields. These fields allow you to position the Va
marker and the Vb marker by entering channel numbers and voltage
levels for these markers.
If you turn the voltage markers on while the time markers are also
turned on, the voltage levels that correspond to the time marker
waveform crossings will be deleted from the channel label field. If you
turn the voltage markers off while the time markers are turned on, the
voltage levels that correspond to the time marker waveform crossings
will appear in the channel label field.
Va On fiel d
The Va marker is shown on the waveform display as a horizontal
dashed line.
The Va On field assigns the Va marker to one of the oscilloscope
acquisition channels. The default channel is channel 1.
The channel selected for assignment to the Va marker does not have to
be displayed in the waveform area. If the selected waveform is not in
the waveform area of the screen, the Va marker will not be displayed. If
there are multiple occurrences of the selected waveform in the
waveform area of the screen, only the uppermost occurrence of the
waveform will display the Va marker.
