The Tektronix TDS7404B is a 4 GHz digital phosphor oscilloscope engineered for verification, debug, and characterization of high-speed electronic designs. It delivers exceptional signal acquisition and analysis capabilities with DPX® technology enabling >400,000 waveforms per second—ideal for capturing rare glitches and transient events. The instrument combines classic analog-style front-panel controls with a 10.4-inch touch-sensitive color display and graphical menus for intuitive operation. An open Microsoft Windows environment supports extensive customization, third-party software integration, and personalized control windows via MyScope® functionality.
