The '''Tektronix 2245''' is a 100 MHz four-channel analog oscilloscope. | The '''Tektronix 2245''' is a 100 MHz four-channel analog oscilloscope. | ||
Channels 1 | 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 | 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. | ||
