🔍 Overview: What Is the Yokogawa AQ6370D OSA?
The Yokogawa AQ6370D is a benchtop optical spectrum analyzer designed to measure the power distribution of optical signals across a broad wavelength range. It is widely used in fiber optics, photonic research, telecommunications, biomedical instrumentation, and manufacturing test stations.
🌐 Key Technical Specifications:
| Feature | Value |
|---|---|
| Wavelength Range | 600 – 1700 nm |
| Wavelength Accuracy | ±0.01 nm |
| Resolution Bandwidth (RBW) | 20 pm to 2 nm |
| Dynamic Range | Up to 78 dB |
| Level Accuracy | ±0.5 dB |
| Optical Input | SMF (FC/APC, FC/PC), MMF (Optional) |
| Sweep Speed | High-Speed, Auto, Repeat, and Segment Modes |
| Interface | USB, GPIB, Ethernet (LXI-compliant) |
This level of resolution and accuracy makes the AQ6370D one of the most versatile OSAs in the market for both narrowband laser sources and broadband optical signals.

❗ Common Failures & Malfunctions in AQ6370D
Even Yokogawa’s premium devices are susceptible to failure over time, especially in demanding lab or production environments. At Aumictech, we frequently repair:
🔧 Internal Issues:
- Wavelength reference drift due to aging reference source
- Faulty diffraction grating / monochromator misalignment
- Internal sensor and photodetector failures
- Overheating or PSU board failure
🔧 Optical Issues:
- Damaged input connectors (FC/APC, FC/PC)
- Signal dropouts or distorted spectrum traces
- Dirty or cracked input lenses and internal optics
🔧 Software and Firmware:
- Frozen display or stuck boot screen
- Missing sweep or inconsistent resolution bandwidths
- Error codes (E0007, E1015, etc.)
All these issues are repairable by our specialized lab at Aumictech using OEM-quality components, precision alignment equipment, and original test protocols.
