The Tektronix TVS641 is a 4-channel VXI waveform analyzer built for high-speed signal acquisition and mixed-signal test environments. Operating at 250 MHz bandwidth with 1 GS/s sample rate across all channels, it delivers real-time sampling at intervals as short as 200 ps/point. The instrument captures fast transients and transient sequences using digital real-time acquisition technology, supporting multiple acquisition modes including Auto-Advance with time-stamped event capture, Envelope, and Average. Signal integrity applications benefit from its extensive triggering options, post-acquisition analysis, and waveform math capabilities including FFT analysis and automatic measurements. High-speed data transfer and full SCPI programmability enable seamless integration into VXI-based test systems.
