The Tektronix TVS645A is a 4-channel, 1 GHz VXI waveform analyzer engineered for high-speed signal acquisition and real-time analysis. It captures simultaneous single-shot waveforms across all four channels at up to 5 GS/s, with record lengths reaching 30,000 samples per channel in extended acquisition mode. Sample intervals as short as 200 ps/point and channel-to-channel delay under 100 ps enable precise characterization of complex transient signals in demanding test environments.
