dGroup
Use the commands in the Cursor Command Group to control the cursor display
and readout. You can use these commands to control the setups for cursor 1 and
cursor 2, suc
h as cursor position.
You can also use the commands to select one of the following cursor functions:
Off. Turns off the display of all cursors.
Waveform Cursors. Consists of two cursors. Waveform cursors enable you
to conveniently measure waveform amplitude and time.
Screen Cursors. Consists of two pairs of independent horizontal and vertical
cursors. You can use these cursors to indicate an arbitrary position within
the waveform display area.
