The Tektronix TVS641A is a 4-channel VXI waveform analyzer delivering 250 MHz bandwidth and 1 GS/s sample rate for simultaneous multi-channel signal acquisition. This C-size VXI module integrates into test systems via the VXIbus backplane and supports full SCPI command control through message-based interfaces. Real-time sampling intervals as short as 200 ps/point enable precise transient characterization, while multiple acquisition modes—auto-advance with time-stamping, envelope, and average—address both single-event and statistical measurement requirements. The analyzer captures up to 15,000 samples in real-time mode or 30,000 samples in extended real-time mode per acquisition cycle.
