The Tektronix 11801 is a digital sampling oscilloscope that takes four 11800 series plug-in sampling modules. Input channel capacity can be expanded up to 68 sampling modules (136 channels) using up to four SM-11 Multi-Channel Units if option 1M is installed in the 11801.

The 11801 design team included Murlan Kaufman, Stan Kaveckis, Agoston Agoston, John Carlson, John Rettig, Jon Lueker, and Roy Lewallen.

The 11801A update was introduced in 1991, the 11801B in 1994, and the 11801C by 1997.

The CSA803 is effectively a variant of the 11801.
