The Legacy of the Ando AQ6317B Optical Spectrum Analyzer
The Ando AQ6317B, introduced by Ando Electric Co. (later acquired by Yokogawa), was one of the most advanced optical spectrum analyzers of its time. Even today, decades later, it is still widely used in laboratories, universities, telecom companies, and manufacturing environments.
Key Features of the AQ6317B
- Wavelength Range: 350 nm – 1750 nm (covering visible and NIR spectrum)
- Wavelength Accuracy: ±0.01 nm (typical)
- Resolution Bandwidth: Selectable from 0.01 nm to 5 nm
- Dynamic Range: Up to 70 dB
- Input: Single-mode fiber, with options for multimode testing
- Measurement Speed: Optimized sweep speeds for production use
- Applications: Telecom (DWDM, OSNR), laser diode analysis, LED characterization, fiber optic component testing
This wide wavelength range makes the AQ6317B versatile for both telecom applications (C-band, L-band) and research applications (visible spectrum, fiber sensors, material studies).
Why Calibration is Critical for the Ando AQ6317B
1. Ensuring Measurement Accuracy
The AQ6317B measures wavelength, power, and OSNR with high precision. Over time, internal references drift, leading to inaccurate results. For telecom or R&D work, even a 0.1 nm shift can lead to compliance issues.
2. Compliance with Industry Standards
Companies in telecommunications, aerospace, defense, and medical device industries must comply with strict testing requirements. Annual calibration, with NIST-traceable certificates, ensures your test results remain valid.
3. Extending Instrument Life
Calibration is not just about accuracy — it also includes preventive maintenance. Our technicians at Aumictech clean optics, replace aging components, and check the entire signal path to prevent costly failures.
4. Maintaining Resale Value
A calibrated AQ6317B with a certificate from a trusted lab like Aumictech holds its value longer, making it a better investment when it comes time to upgrade.
Common Issues with the Ando AQ6317B
Despite its robust build, the AQ6317B can develop issues after years of use. At Aumictech, we frequently repair the following:
- Wavelength Drift: Internal reference lasers shift over time.
- Optical Input Damage: Fiber connectors wear out or become misaligned.
- Power Supply Failures: Fans, capacitors, or regulators degrade.
- Display Malfunctions: The LCD can dim, flicker, or fail entirely.
- Mechanical Issues: Keypads, rotary knobs, or buttons lose responsiveness.
- Firmware Errors: Old firmware may lock up, requiring reprogramming.
Our team carries specialized parts, optical modules, and diagnostic tools to restore AQ6317Bs to full working condition.
