This unit
The Yokogawa AQ6377 is a optical spectrum analyzer for precise characterization across the 1900–5500 nm wavelength range. Using dispersive spectroscopy, it delivers measurements from –60 dBm to +13 dBm with 50 dB close-in dynamic range and wavelength accuracy of ±0.5 nm. The instrument features a free-space optical input for high coupling efficiency and maintenance-free operation, an integrated gas purge system to suppress water vapor absorption, and a built-in cut filter that removes high-order diffraction below 1500 nm.
Wavelength resolution spans 0.2 nm to 5 nm across selectable display modes: wavelength (nm), frequency (THz), or wave number (cm⁻¹). Applications include environmental sensing, medical diagnostics, gas analysis, quantum cascade laser characterization, and advanced photonic research.

Frequently Asked Questions
- What does the Yokogawa AQ6377 measure, and what is its wavelength range?
- The AQ6377 is a high-resolution optical spectrum analyzer that measures optical power across the infrared and near-infrared spectrum from 1900 nm to 5500 nm (0 to 158 THz). It delivers selectable spectral resolution from 0.2 nm to 5 nm with ±0.5 nm wavelength accuracy, making it suitable for characterizing broadband sources, filtering devices, and WDM component testing. The power measurement range spans −60 dBm to +13 dBm, covering both weak and moderately strong optical signals.
- What is the condition of this used AQ6377, and what has been verified?
- This unit is offered in used condition and has been functionally tested and inspected before listing. We verify core measurement capability and optical port integrity as part of our standard pre-sale evaluation. For customers requiring a full calibration certificate traceable to NIST standards, calibration is available separately starting at $450.
- Is calibration available for the AQ6377, and what does it cost?
- Yes, calibration services are available for the AQ6377 starting at $450 and can be arranged separately from your purchase. A full calibration typically includes wavelength accuracy verification, power level certification, and issuance of a traceable calibration certificate. Please contact Aumictech directly for current lead times and specific calibration scope details.
- What interfaces and connectivity options does the AQ6377 support?
- The Yokogawa AQ6377 supports GPIB (IEEE 488) remote control for integration into automated test systems and data acquisition setups. The instrument is compatible with Yokogawa's proprietary software drivers and standard SCPI command sets for instrument communication. Please verify the specific interface requirements for your application, as legacy equipment may require adapter cables or USB-GPIB converters for modern computing environments.
