Yokogawa AQ6370E Spectrum Analyzer OSA has a versatile wavelength range of 600 nm to 1700 nm, ideal for both telecom and general purpose applications. The unique free-space input design allows testing of both DWDM-class single-mode and VCSEL-sourced multimode fibers in a single model and the high-speed measurement mode, high close-in dynamic range mode, touch panel, and APP function greatly improve measurement efficiency.
World-Class Optical Performance- Wavelength range: 600 to 1700nm
- High wavelength accuracy: ±0.008 nm typ.
- High wavelength resolution: 0.02nm
- Wide dynamic range: 78dB typ.
- Wide level range: +20 to -90dBm

There are two models available, Standard and High performance. The High performance model provides even higher wavelength accuracy and dynamic range.
High wavelength resolution: 0.02nm
High Wavelength Accuracy: ±0.008 nm typ.
- High performance model: ±0.008 nm typ. (C band)
- Standard model: ±0.015 nm typ.(S+C+L band)
| Wavelength range | Standard (-10) | High performance (-20) |
|---|---|---|
| 1520 to 1580 nm | ±0.015 nm | ±0.008 nm |
| 1450 to 1520 nm 1580 to 1620 nm | ±0.015 nm |
Note: The wavelength accuracy values in the table are typical values.
Ultra-High Dynamic Range: 78dB typ.
With the reduced stray-light in the monochromator, AQ6370E achieves ultra-high dynamic range of typ. 78dB.

Sharper spectrum measurement: HCDR mode
The HCDR (High Close-in Dynamic Range) mode is a feature for single longitudinal mode laser measurements that makes the spectrum around the peak sharper and the side modes more clearly visualized.
This mode is only available on the High performance model(-20).
Stray-light suppression ratio: 80dB typ.
This new specification provides stray-light suppression capability when High dynamic mode, usually taking longer measurement time, is not used. The AQ6370E contributes to shortening the measurement time with the high stray light suppression ratio.
| Standard (-10) | High Performance (-20) |
| 73dB | 76dB (Typ. 80dB) |
| *Resolution setting 0.1nm | |
Wide Level Range: +20DBm to -90dBm
The AQ6370E can measure high power sources such as optical amplifiers and pump lasers for Raman amplifiers, and very weak optical signals as well. Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements.
Improved level sensitivity: -85dBm (1000 to 1300nm)
Smoothing Function - Reduce noise on the measured spectrum
High dynamic mode - Obtain a better dynamic range by reducing the influence of stray-light, which is caused when the input is a strong optical signal.
- Multimode and single mode fiber on the same OSA.
- AQ6370E's low insertion loss for multimode fiber is also beneficial to maintain the excellent measurement efficiency.
- Small insertion loss variation at the input
- connector increases measurement repeatability.
- No damage connecting fibers
- because there is no physical contact.
- APC level correction
- The APC level correction function corrects the level offset caused by an insertion loss of angled PC connector.
