The Tektronix 2245 is a 100 MHz four-channel analog oscilloscope, introduced in 1987 (2245A in 1988).

Channels 1 and 2 are full-featured, whereas 3 and 4 are limited in both deflection factor and coupling, as they are intended mainly for digital and trigger signals.

The 2245 includes features like AUTO SETUP which automatically adjusts vertical, horizontal, and triggering and display controls to provide a stable, triggered display of the waveform in seconds. It offers a dual time base with delayed sweep, and cursor time/voltage measurements with on-screen readout of cursor data and scale factors.
