The Tektronix 2235 is a rugged, lightweight, dual‐channel analog oscilloscope designed for both bench-top and portable field use. It delivers a 100 MHz bandwidth and dual timebase functionality, offering both alternate and chop trace modes for simultaneous signal comparison. The instrument features an 80 × 100 mm cathode-ray tube that produces a bright, sharply defined trace, and its vertical system is calibrated from 2 mV/div to 5 V/div. With a rise time of approximately 3.44 ns, the 2235 accurately captures fast transient events, and its straightforward front-panel controls simplify measurement setup and waveform analysis.
