The Tektronix TDS310 is a classic two-channel 50 MHz digital storage oscilloscope designed for benchtop and field service applications. Combining a responsive 200 MS/s real-time sample rate on both channels with a legacy 7-inch monochrome CRT raster display, it offers essential signal capture capabilities, automated waveform measurements, and robust trigger modes in a compact, portable format.
