The pre-owned Yokogawa AQ6317B delivers laboratory-grade optical spectral analysis across the full 600 nm–1750 nm window. Its 0.015 nm resolution and 70 dB dynamic range separate densely spaced DWDM channels from ASE noise in a single sweep, while –90 dBm sensitivity captures faint signals without an external pre-amplifier. An internal acetylene calibrator maintains ±0.5 nm absolute wavelength accuracy, and fast scan modes with SCPI/LAN control keep production throughput high.
Refurbished units ship ISO-17025-calibrated with current firmware, trimming capital expense and lead-time yet preserving Yokogawa reliability, connector flexibility and long-term serviceability.
