Automatic Verification System for Signal Generator

Based on its system configuration, hardware design, system and measurement programming and adjusting, and error analysis and processing, the automatic verification system for signal generator has the abil- ity to automatically verify the performance of synthesized signal generator for RF and microwave with frequency up to 26.5 GHz. All of the 26 parameters of frequency, power, modulation, spectrum purity, distortion, etc. can be automatically verified by its single connection, and the operation modes can be manual, semi-automat- ic, and automatic. There are more than 40 types of signal generator that have already been verified by this ver- ification system, and the generators needing verification can be automatically added to the system in real time. The standard instrument configurating design of this verification system is open and convenient for replacement. The system operates reliably, accurately, and speedily. The system has high value of application and dissemination because of its good design in compatibility, adaptability and functionality. This system can be widely used in measurement services for automatic verifying signal generator. This system is a direction for the development of measurement verification, and has very directive function for realizing automatic measurement verification for RF and microwave instruments.
