The Tektronix TDS460A is a professional-grade 400 MHz, 4-channel digital storage oscilloscope featuring a real-time sample rate of 100 MS/s on all channels simultaneously. Designed for precision laboratory measurements and debugging, it offers a robust vertical DC gain accuracy of ±1.5% and a standard 30k point record length (upgradeable to 120k with Option XL). It also includes a built-in floppy disk drive, extensive automatic measurements, advanced triggering (including video triggers), and flexible acquisition modes like 10 ns Peak Detect.
