III. Turn on/off channels
CH1, CH2 and Ext. Trigger channels are input channels. All functions applied will base
on operating the instrument with channels, so MATH and REF can be regarded as
relatively isolated channels.
Press the corresponding button on the front panel to turn the channels on/off. The
backlight indicates the channel is currently active. Press the button again to turn the
channel off. When channel is currently selected, press OFF will turn it off and the
backlight goes off.
