The Tektronix 11402 is a digitizing oscilloscope that accepts three 11000-series plugins and has a built-in time base.

It supports up to 8 input channels (e.g. 2 * 11A34) and uses equivalent-time digitizing for repetitive source signals.

The 11403 is the same as the 11402A but with a color screen.

Project manager for the 11400 series was Tom Rousseau, assistant project manager and person responsible for the touch panel and display was Murlan Kaufman.
