Adopting the new generation AC/DC superposition test theory to adapt to high precision and high frequency testing requirements.
This device adopts a new generation of AC/DC superposition test theory, adapting to high precision and high frequency testing requirements. The high-performance built-in embedded MCU can quickly respond to the status or malfunction of the host and slave machines, providing real-time display. This helps improve work efficiency. The newly designed user-friendly graphical operating interface includes five foot control modes and full touch operation, offering convenience and efficiency to users. The new file management system allows for easy, quick, and accurate operations, capable of storing 99 groups of real-time setting files and user-defined setting files. It can provide push information display and cache 2 real-time information. With a two-mode SCPI command system, it is convenient for production line setup and unit testing. It can also connect with any device equipped with a serial port, referring to the SCPI command system design of this machine.
