High Accuracy Used Optical Spectrum Analyzer Agilent 86142A 600 – 1700 Nm

The pre-owned Agilent 86142A delivers laboratory-grade optical spectral analysis across the full 600–1700 nm window, combining 0.06 nm resolution with a 70 dB dynamic range so dense DWDM channels and ASE pedestals are clearly separated in a single sweep. Typical –90 dBm sensitivity captures faint ASE tails and narrow-line lasers without an external pre-amp, while the built-in wavelength calibrator maintains ±0.5 nm absolute accuracy—crucial for compliance testing of EDFAs and passive components. Fast 40 nm / 50 ms scans and SCPI/LAN control accelerate production, and option plug-ins add EELED sources or wavelength calibrators for in-situ device characterisation.

Refurbished units ship ISO-17025-calibrated with the latest firmware, cutting capital expenditure and lead-time yet preserving Agilent 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.
