The command parameter is a quoted model number string. The available model number strings are shown in the graphical user interface (GUI) or in the GUI's Interactive SCPI Command Tree.

## Description

Selects a known Keysight extension cable (with known compensation values).

To turn on and off compensation for the selected Keysight extension cable, use the `:CHANnel:PROBe:ACCessories:ECABle:STATe` command.

When using an extension cable that is not a known Keysight model, it can be considered external hardware, and you can specify its attenuation/gain/dB settings using the :CHANnel External Scaling Commands.
