Abstract

Abstract

An automatic verification system for octave-band and fractional octave-band filters based on LabVIEW was designed to improve the efficiency and accuracy of verification. The system uses a computer as the core controller and employs the virtual instrumentation technology. By using standard interfaces to connect the instruments that need remote control, a reference signal source and the parts under measurement are integrated into a single system. Following the verification regulation, the system realizes automatic control of instruments, automatic reading of response data, data analysis and processing, and generation of raw data report, etc. Multiple tests show that the system is stable and reliable and lends itself to improving efficiency and accuracy and avoiding human errors.
