Ando AQ6140 Multi-Wavelength Meter

The Ando AQ6140 is a multi-wavelength meter for precise optical signal measurement and analysis across Dense Wavelength Division Multiplexing (DWDM) systems. It simultaneously measures wavelength and power for up to 256 channels with high accuracy and resolution, displaying waveforms and results in real time on a 6.5-inch color LCD. The instrument supports grid monitoring aligned with ITU-T recommendations, drift and stability analysis, and includes marker functions for detailed wavelength and power comparisons.
