The Tektronix WVR4000 is a compact 1 RU half-rack waveform rasterizer engineered for SD-SDI video monitoring and quality control in broadcast and production environments. It delivers fully digital processing for drift-free, repeatable waveform analysis with CRT-like trace quality. The instrument provides dual passive loop-through BNC video inputs (75 Ω compensated), DVI-I display output, embedded audio monitoring across 16 channels, and comprehensive error logging for 10,000 events.
