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