The pre-owned Yokogawa AQ6375B extends high-resolution spectrum analysis into the extended-NIR band, resolving spectral detail from 1.2 µm to 2.4 µm with 0.05 nm resolution and ±0.05 nm wavelength accuracy locked by an internal reference source. A 55 dB close-in dynamic range, –70 dBm sensitivity and +20 dBm headroom allow one-sweep characterisation of narrow-line DFB lasers, broadband super-continuum sources and high-power EDFAs. Gas-purge ports and an integrated high-order cut filter suppress water-vapour absorption and diffracted-light artefacts, while double-speed sweep mode halves acquisition time in production. Supplied fully tested, freshly calibrated and firmware-current, each unit offers traceable Yokogawa precision and automation-ready USB/LAN/GPIB control at a fraction of new-instrument cost.
