Turn on or off Channels
CH1, CH2, CH3, CH4 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 (for example: CH1, CH2, CH3, CH4, MATH, REF) on
the front panel to turn the channels on. The backlight indicates the channel is
currently active. When a channel is currently selected, press the button with respect
to the channel again will turn it off and the backlight goes off. When a channel is not
currently selected, press the button associated with the channel will select the
channel as the current channel.
