The Tektronix TDS220 is a 100 MHz, 2-channel digital oscilloscope delivering 1 GS/s real-time acquisition across all channels. Built for design validation, debug workflows, production testing, and educational laboratories, this instrument captures signals with 8-bit vertical resolution and up to 2,500 sample points per channel. Its compact 2.9 kg form factor and intuitive interface make it ideal for bench-top and field deployment.
