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 4 SM-11 Multi-Channel Units if option 1M is installed in the 11801.

The 11801A update was introduced in 1991, the 11801B in 1994.

The CSA803 is effectively a variant of the 11801.
