The Teledyne LeCroy WaveRunner 735Zi is a 3.5 GHz digital oscilloscope engineered for high-speed signal integrity and protocol analysis. With four analog channels, selectable 50 Ω or 1 MΩ input impedance, and sampling rates to 40 GS/s, it captures transient and repetitive signals with 8-bit vertical resolution (11 bits with ERES). The instrument delivers ±1.5% DC gain accuracy and time interval accuracy < 0.06 / SR + (clock accuracy × Reading) rms, meeting stringent measurement requirements across communications, power delivery, and mixed-signal design.
