AQ6317B Yokogawa Optical Spectrum Analyzer 600–1750 Nm 0.015 Nm Resolution

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.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
