The Tektronix 11403 is a digitizing oscilloscope that accepts 11000-series plugins and has a built-in time base, supporting up to 8 input channels. It is identical to the 11402A except that the 11403 uses a color screen.

The 11403A model extends bandwidth to 3 GHz (with 11A81 amplifiers).

It uses equivalent-time digitizing for repetitive source signals.

The assistant project manager and person responsible for the touch panel and display was Murlan Kaufman.
