Manual/Automatic Time Markers option
The manual/automatic combination allows you to have one time marker set to
automatic mode and one time marker set to be controlled manually with the
knob.
Setting the Manual/Automatic Time Markers Option
To set the manual/automatic option, you select the T Markers field and
choose the Auto field from the pop-up. You then select the Set on field for
either the Tx or To marker, and then choose MANUAL from the pop-up menu.
When you choose Done in the auto-markers pop-up menu, you return to the
waveform display. Now when you select the T Markers field again and
choose On from the pop-up menu, the marker you selected with the
MANUAL field is set to the manual mode and the other marker is set to fall
on the parameters you set while in the automatic mode.
Voltage Markers options
When 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 field
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.
