The pre-owned Yokogawa AQ6370B combines a high-performance monochromator with built-in He-Ne referencing to deliver 0.02 nm resolution and ±0.02 nm wavelength accuracy across the key 600–1700 nm telecom band. A 70 dB close-in dynamic range and –90 dBm sensitivity let engineers resolve adjacent DWDM channels, ASE skirts and laser side-modes in a single sweep, while +20 dBm headroom prevents detector saturation during high-power EDFA tests. USB, Ethernet and GPIB interfaces, coupled with fast trace transfer and on-board OSNR and EDFA analysis routines, streamline both R&D debug and production alignment. Shipped fully tested, freshly calibrated and firmware-current, each unit offers traceable Yokogawa precision at a fraction of new-instrument cost—ready for immediate deployment in optical component labs or field service vans.
