The Channel subsystem commands control all vertical (Y axis) functions. To control differential waveforms, use the `:DIFF Subsystem` subsystem.

The commands in the `:CHANnel` subsystem, as well as a few other Infiniium 2026 commands, include a reference (`:CHANnel{N}`) that identifies the channel to which the command applies as shown in the following table. For example, you can display connection 1 channel 1 with any of the following four identical commands. (Notice channel identifier highlighted in red.)

    :CHAN1:DISPlay ON;
    :CHAN1_1:DISPlay ON;
    :CHANnel1:DISPlay ON;
    :CHANnel1_1:DISPlay ON;
