The Tektronix TDS680B is a 1 GHz digital oscilloscope built for electronics testing, signal characterization, and design verification. It acquires waveforms at 5 GS/s per channel across two input channels with 8-bit vertical resolution (>11 bits using averaging). The instrument delivers 1 ns peak detect capability, 25 automated measurements, and advanced triggering—edge, pulse, logic, and optional HDTV video—to capture complex signal behavior. Waveform math, FFT, integration, and differentiation enable on-board signal processing. Pass/fail template testing streamlines verification workflows for digital designs and telecommunications signals. Vertical sensitivity spans 1 mV/div to 10 V/div with 1.5% accuracy. Time base ranges from 200 ps/div to 10 s/div, accurate to ±100 ppm over intervals exceeding 1 ms. Record length reaches 15,000 points per channel. Input options include 1 MΩ || 10 pF or 50 Ω impedance with AC, DC, or GND coupling. The instrument accepts ±400 V peak signals (300 V CAT II) with attenuation above 1 MHz. Color VGA display, RS-232, Centronics, GPIB, and VGA I/O enable integration into automated test systems. Channel deskew is available for precise timing alignment.
