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.
