This unit

The Yokogawa AQ6375E is a optical spectrum analyzer delivering precise spectral measurements across the 1200–2400 nm wavelength range. Engineered for telecommunications, optical device characterization, and production environments, it combines superior resolution, extended dynamic range, and rapid sweep capability to provide detailed analysis of optical signals in the extended near-infrared spectrum. The instrument measures spectral amplitude from –70 dBm to +20 dBm with ±0.5 dB accuracy at 1550 nm, achieving more than 50 dB dynamic range at 0.1 nm resolution.


Its selectable resolution bandwidths span 0.05 nm to 10 nm, supporting wavelength accuracy of ±0.1 nm (1500–1700 nm) and ±0.2 nm (1200–1500 nm, 1700–2400 nm). With minimum sweep times of 0.2 seconds over 50 nm ranges and full-featured analysis functions, the AQ6375E enables rapid characterization of lasers, optical amplifiers, filters, and passive components.
