The Tektronix TDS2002B is a 60 MHz, 2-channel digital storage oscilloscope engineered for signal acquisition, analysis, and troubleshooting in design, debug, education, and manufacturing environments. It delivers 1.0 GS/s real-time sampling with a 2.5 k standard record length, color LCD display, and advanced triggering to capture critical signal events. The instrument combines vertical sensitivity from 2 mV/div to 5 V/div with ±3% accuracy and a time base range spanning 5 μs/div to 50 s/div. Edge, pulse width, and video triggering modes isolate transient phenomena, while trigger sensitivity reaches 12 ns typical across all time base settings.
