The AQ6370E is the new model in Yokogawa's most popular telecom class OSA. With a versatile wavelength range of 600 nm to 1700 nm, it is ideal for both telecom and general purpose applications. The unique free-space input design allows him to test both DWDM-class single-mode and VCSEL-sourced multimode fibers in one single model.
The new high-speed measurement mode, high close-in dynamic range mode, touch panel, and APP function greatly improve measurement efficiency.
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
|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
Note: The wavelength accuracy values in the table are typical values.
With the reduced stray-light in the monochromator, AQ6370E achieves ultra-high dynamic range of typ. 78dB.

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).

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.
The SMSR mode is the sensitivity setting dedicated for measuring the laser’s SMSR faster.
It can measure the SMSR up to twice as fast as the conventional sensitivity mode (TRAD MIDx2).
Note: Fast measurement may not be possible depending on the level of the optical spectrum.
The 20,001 data sampling points expands measurement range in a single sweep while keeping a high wavelength resolution.
This makes your measurement easier and more efficient than conventional systems.
The high-resolution, responsive 10.4-inch multi-touch capacitive touchscreen makes device operation even simpler and more intuitive. You can change measurement conditions, perform analysis, change the optical spectrum view as if you were operating a tablet device. In the optical spectrum view, the waveform view can be zoomed or shifted by a simple tap and drag.
Four USB ports in total available on front and back facilitate the use of external devices such as a mouse, keyboard, external hard drives, and memory sticks.
The thumbnail allows an easy route to quickly find a particular file out of many files in internal and external storage.
This time-saving feature allows the user to save all seven traces in one file at once. Files are saved in CSV format and can be easily manipulated with a PC application software.
Application (APP) mode transforms a versatile OSA into a machine dedicated to a device under test (DUT). APP mode provides a DUT-specific user interface that navigates the user from configuration settings to test result output without the user being aware of the wide variety of OSA settings.
The AQ6370E comes pre-installed with several basic applications such as WDM testing, DFB-LD testing, and FP-LD testing. In addition, the application can be downloaded from the Yokogawa website and added to the AQ6370E for use.

The Gate Sampling function facilitates the recirculating loop testing of optical transmission systems. Using an external gate signal, the AQ6370E obtains the optical spectrum of the signal which is passing through a certain loop. The advantage of this approach is its speed compared with the conventional External Trigger or Sweep Enable function.
The Resolution Calibration function is used to calibrate the noise equivalent bandwidth with an external light source. With this new feature, the measurements of power density of a broad spectrum light source will be more accurate

for popular applications, such as:
Fast Remote Interfaces
Ambient condition change, vibration and shock to an optical precision product, like an optical spectrum analyzer, will effect the optical components, and eventually degrade optical performance. Using standard functions, AQ6370E can maintain its high optical performance within a couple of minutes so that you can quickly start a measurement.

AQ6370E's overall high performance can cover not only manufacturing of optical devices and optical transmission systems but also research and development, and a variety of other applications.
The free space beam from device level optical sources for LiDAR, 3D sensing, Wafer Chips, optical transceiver TOSAs and laser diodes (LD) in general may be conveniently coupled to a fiber input using various beam capture solutions to optimize the spectral detection performance of the OSA.
For performing long term testing of extreme temperature effects for automotive LiDAR devices as an example, learn how the Data Logging Function can be utilized to eliminate time consuming program development and validation.
AQ6370E's wide close-in dynamic range allows accurate OSNR measurement of DWDM transmission systems (up to 50 GHz spacing). The built-in WDM analysis function analyzes the measured waveform and shows peak wavelength, peak level and OSNR of WDM signals up to 1024 channels simultaneously.
The ASE interpolation method is used to measure gain, NF, and key parameters for optical fiber amplifier evaluation. With WDM-NF analysis function, up to 1024 channels of multiplexed signals can simultaneously be tested. An ASE level for NF measurements is calculated by using a curve-fit function for each WDM channel.
By connecting a GI 50 or GI 62.5 optical fiber with a relatively large NA to the NA Conversion Fiber, the NA Conversion Fiber reduces the loss that occurs at the input and improves the measurement dynamic range during passive device measurements and the stability of optical level measurements during active device measurements.
