Turn on/off Channels
The CH1, CH2, Ext. Trigger and LA (DS1000D series) channels are input channels.
All functionalities applied will be based on operating the instrument with channels.
So MATH and REF can be regarded as relatively isolated channels.
To turn on/off any one of the channels, press the corresponding button on the front
panel. The key backlight indicates the channel is currently active. Press the button
again to turn the channel off. Or when channel is currently selected, press OFF will
turn the channel off as well, and the key backlight also goes off.
The channel status symbol is displayed at the lower-left of the screen, which can
help users to judge the channel status quickly.
