The Tektronix 2225 is a 50 MHz, two-channel analog oscilloscope designed for general-purpose signal analysis in educational, field service, and production environments. Its high-resolution CRT display delivers clear waveform visualization across a 8×10 division graticule. With vertical sensitivity from 2 mV/div to 5 V/div, adjustable time-base speeds from 0.05 µs/div to 0.5 s/div, and flexible trigger options, the instrument supports AC, DC, and component testing workflows. Engineers and technicians benefit from straightforward operation and ±3% measurement accuracy on both vertical and horizontal axes.
