Insertion loss is an important parameter used to characterize passive fiber-optic components, such as WDM couplers and variable optical attenuators. This article describes an automated insertion loss measurement system which incorporates 980 nm, 1310 nm, 1529 nm and 1561 nm DFB lasers and two internal fiber optic standards. Insertion loss measurements collected with the system for WDM couplers and internal standards are presented. The system repeatability was validated by measuring the insertion loss for a WDM coupler six times at 980 nm, 1310 nm, 1529 nm and 1561 nm over 3 days period. The standard deviation calculated for the insertion loss measurements is less than 0.11 dB and the %CV is less than 1%.

A dynamic magnetic measurement system for soft magnetic material based on virtual instrument technology is presented. High frequency AC excitation power supply is adopted to drive soft magnetic material. High speed data transport system composed by FPGA chip ALTERA EP1C12Q240C8N and USB microcontroller Cypress CY7C68013A. The problem of phase-shift of hardware integrator which is difficult to control is solved by digital integration. LabVIEW with powerful data processing capabilities is used to simplifies the hardware structure and improve the testing accuracy and automation level of measurement. The paper also points out problems of digital integration and gives a solution.
