Capable of checking if it’s matched to advice of ITU-T and severe monitoring of grid. Also capable of displaying the list of peak wavelength and power. Long-term function Displays changes of peak wavelength and power of one channel. Below waveforms, displays not only current measurement result but also maximum rate, minimum rate or balance of maximum rate and minimum rate. Grid monitoring function Analyzes peak wavelength of set grid. Searches peak wavelength, or analyzes wavelength gap and changes of power within the grid. Standard screen The waveform and the peaks are displayed simultaneously on the standard screen. It is used to monitor WDM system temperature characteristics and evaluate laser oscillators. 3D display screen Displays 3D waveforms and peak lists at a time. It helps to check the change of measurement result by time. List screen This mode displays a list of the peak wavelengths, up to 14 at a time. Marker screen The marker function simplifies tasks such as analysis of wavelength and power level difference. Label input screen Label can be input up to 36 characters, so that file management can be easy. File screen Measured waveform data can be saved in a variety of file formats. The file recall function makes it possible to make new measurement with the same measurement conditions as saved data, which is ideal for WDM system maintenance. Practical application in recent years of Wavelength Division Multiplexing (WDM) transmission technology for high-volume optical communication has led to the current situation in which we’re on the verge of producing 50 GHz-wavelength systems. Accordingly, demand for a higher-specification wavelength parameter tester is increasing. Such a tester can go a long way toward improving evaluation of transmission systems and optical devices. The Ando AQ6140 Multi-Wavelength Meter, providing excellent wavelength accuracy and resolvable separation in measurement, surpasses this demand, making it ideal for all applications from D-WDM system development to manufacturing.
