The Agilent/Keysight 70004A is a 4-slot color system display mainframe serving as the front-end interface for the HP 70000 Series Modular Measurement System. It integrates a color CRT display with mainframe functionality, enabling simultaneous control and monitoring of up to four modular instruments. The unit combines a 7.5-inch diagonal display with flexible module accommodation supporting 1/8-, 1/4-, 3/8-, and 1/2-width modules, making it suitable for demanding R&D, manufacturing, and quality control applications in telecommunications and high-frequency electronics.
