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

The commands in the :CHANnel subsystem, as well as a few other FlexDCA 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 channel 1A with any of the following four identical commands. (Notice channel identifier highlighted in red.)

:CHAN1:DISPlay ON;
:CHAN1A:DISPlay ON;
:CHANnel1:DISPlay ON;
:CHANnel1A:DISPlay ON;

To simplify the documentation of these commands, the channel identification portion each of these commands will be represented by {N} as shown here:

CHANnel{N}:BANDwidth

Interpolation/Range (FlexRT)

Use these :CHANnel subsystem commands to apply selected channel overides to universal (shared) settings that configure how FlexRT interpolates and samples the channel waveform. The universal settings are made in the Infiniium Scope Setup dialog or programmatically using the universal interpolation commands and universal range commands.

To enable or disable the use of shared software clock recovery settings with the selected channel, use the :CHANnel:RTSCope:TRACk command.

Software CDR (FlexRT)

Use these :CHANnel subsystem commands to apply selected channel overides to universal (shared) settings that configure how FlexRT applies software clock recovery on the Infiniium waveform. The universal settings are made in the Infiniium Scope Setup dialog or programmatically using the universal software clock recovery commands.

To enable or disable the use of shared software clock recovery settings with the selected channel, use the :CHANnel:RTSCope:TRACk command.
