To set up the vertical window
The following exercise guides you through the vertical keys, knobs, and
status line.
1
Center the signal on the display with the Position knob.
The Position knob moves the signal vertically, and it is calibrated. Notice
that as you turn the Position knob, a voltage value is displayed for a short
time indicating how far the ground reference is located from the center of the
screen. Also notice that the ground symbol on the right side of the display
moves in conjunction with the Position knob.
Measurement hints
If the channel is dc coupled, you can quickly measure the dc component of the
signal by simply noting its distance from the ground symbol.
If the channel is ac coupled, the dc component of the signal is removed allowing
you to use greater sensitivity to display the ac component of the signal.
