There are several other things to observe:
The channel readout on the display now shows the settings for both Ch1
and Ch2.
There are two channel indicators at the left edge of the graticule. Right
now, they overlap.
The light by the CH 2 button is now on, and the vertical controls are
now set to adjust channel 2.
The trigger source is not changed by adding a channel. (You can change
the trigger source by using the TRIGGER MENU.)
5. Turn the vertical POSITION knob clockwise to move the channel 2
waveform up on the graticule. Notice that the channel reference indicator for
channel 2 moves with the waveform.
6. Press VERTICAL MENU
➞ Coupling (main).
The vertical menu gives you control over many vertical channel parameters
(Figure 2–12). Although there can be more than one channel displayed, the
vertical menu and buttons only adjust the selected channel.
Each menu item in the Vertical menu displays a side menu. Right now, the
Coupling item in the main menu is highlighted, which means that the side
menu shows the coupling choices.
7. Press
(side) to toggle the selection to 50 ; this changes the input
coupling of channel 2 from 1 MW to 50 W. The channel readout for
channel 2 (near the bottom of the graticule) now shows an W indicator.
