The Tektronix TVS641A is a 4-channel VXI waveform analyzer designed for mixed-signal testing and high-speed data acquisition. Operating at 250 MHz bandwidth with real-time sampling to 1 GS/s, it captures simultaneous single-shot waveforms across all channels at rates up to 5 GS/s. The instrument delivers sample intervals as short as 200 ps/point and supports multiple acquisition modes—Auto-Advance, Envelope, and Average—each with programmable triggering via edge, pulse, delayed, and main trigger configurations. Input signals are conditioned through selectable 50 ohm or 1 MΩ impedance front ends with sensitivity from 10 mV to 100 V full scale, compatible with Tektronix active and passive probes.
