The Tektronix 2245 is a 100 MHz four-channel analog oscilloscope. Channels 1-2 are fully-functional, whereas 3-4 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; Dual Time base with Delayed Sweep; Cursor Time/Voltage Measurements; On-Screen Scale Factor Readouts.
