The Tektronix TVS621A is a two-channel, 250 MHz waveform analyzer engineered for VXI-based systems requiring high-speed signal acquisition and real-time analysis. Built on proven digital real-time acquisition technology from the TDS 600 Series, it delivers simultaneous single-shot capture across independent channels at sample rates up to 1 GS/s. The instrument combines 8-bit vertical resolution with selectable 50 Ω or 1 MΩ input impedance and sensitivity spanning 10 mV to 100 V full scale, making it suitable for mixed-signal characterization, transient event capture, and signal integrity applications.
