Tektronix TVS625 Waveform Analyzer, 2-Channel, 250MHz, 1 GS/s

The Tektronix TVS625 is a VXI-based waveform analyzer delivering 2-channel simultaneous signal acquisition at 1 GS/s across a 250 MHz bandwidth. Purpose-built for high-speed transient capture and signal integrity analysis, the TVS625 combines real-time digitization with advanced waveform processing—FFT analysis, automated measurements, waveform math, and template/limit testing—enabling rapid characterization of complex electronic phenomena in automated test environments.
