Press CH 2.
A second waveform is shown, which represents the signal on channel 2
(CH 2). Since there is nothing connected to the CH 2 input connector, this
waveform is a flat line.
Observe the following things:
H
The channel readout on the display now shows the settings for both
Ch1 and Ch2.
H
There are two channel indicators at the left edge of the graticule.
Right now, they overlap.
H
The light next to the CH 2 button is now on, and the CH 1 light is off.
The knobs control only one channel at a time, so the vertical controls
are now set to adjust channel 2.
H
The trigger readout still indicates that the trigger is detecting trigger
events on Ch1. The trigger source is not changed simply by adding a
channel. (You can change the trigger source by using the TRIGGER
MENU button to display the trigger menu.)
5.
Turn the vertical POSITION knob clockwise to move the channel 2 wave-
form 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 button displays a menu that gives you control
over many vertical channel parameters (Figure 1-12). 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. At the top of the side menu, the
menu title shows the channel affected by the menu choices. That always
matches the lighted channel button.
7.
Press
W
(side) to toggle the selection to 50
W
. That changes the input
coupling of channel 2 from 1 M
W
to 50
W
. The channel readout for chan-
nel 2 (near the bottom of the graticule) now shows an
W
indicator.
