The Tektronix 2-DDU is an installed option designated as the Distribution Demo Unit (DDU). This option is intended for use by Tektronix authorized distributors and is installed on select Tektronix instruments to enable demonstration capabilities. The 2-DDU option is not a standalone product but rather an internal configuration or software setting that allows the instrument to operate in a demonstration mode for evaluation and training purposes. It is not available for general sale and is only provided through official Tektronix distribution channels for demo use.
