To turn an analog channel on or off
• To turn an analog channel on, press the channel number key until it is
illuminated. To turn it off, press the channel number key again.
If you are not using a particular analog channel, you can turn it off. This
simplifies the waveform display and also increases the display update rate.
While a analog channel is turned off, data acquisition continues for that channel.
Therefore, you can still use the analog channel as a source for functions.

Using an Analog Channel as External Trigger
Any analog channel can be used as a trigger source. If you need an external trigger
but do not need all analog channels, you can use an analog channel as an external
trigger without displaying it by turning the analog channel display off.
