The Tektronix TVS641 is a 4-channel waveform analyzer designed for VXI-based test systems, delivering 250 MHz bandwidth and 1 GS/s real-time sampling across all channels simultaneously. This module captures and analyzes transient events with 200 ps sample intervals, offering flexible acquisition modes—Auto-Advance, Envelope, and Average—plus comprehensive internal and external triggering. The instrument combines fast measurement calculation, waveform math, and transform capabilities with high-speed VXIbus data transfer, making it suitable for detailed electronic characterization, rapid event sequencing, and statistical analysis in automated test environments.
