The analyzer does not disable input for channels that are off. It simply does
not display those channels. So, you can assign labels to channels that are off
or use them in a trigger specification. Also, if you turn a channel on after an
acquisition, the data acquired for that channel will be displayed. A channel
must be on, though, if you wish to make measurements using the single- or
dual-channel measurement features.
