AQ6373E Visible Wavelength Optical Spectrum Analyzer 350 - 1200 nm

World-Class Optical Performance

High Resolution & High Dynamic Range
The advanced monochromator achieves high wavelength resolution and high close-in dynamic range. With the sharper spectral characteristics of the monochromator, spectral signals in close proximity can be separated clearly and measured accurately.

High Sensitivity
Weak optical signals can be measured accurately and quickly.

Seven Sensitivity Settings*
The sensitivity settings can be selected according to test applications and measurement speed requirements.
*Except Limited Model

High Dynamic Mode
The dynamic range can be improved by reducing the influence of stray-light, which is caused when the input is a strong optical signal.

Peak-Hold & External Trigger Mode
The pulse peak spectrum of a pulsed light signal is measurable. Often used in the transmission loop testing of telecommunication systems, and also in the low power measurement at the early stage of laser chip development to catch the peak power of a pulsed signal.

Free Space Input
Free space input enables multimode and single-mode fiber on the same OSA and small insertion loss variation at the input connector increases measurement repeatability. Because there is no physical contact, no damage results when connecting fibers. This feature supports SM, GI (50/125 μm, 62.5/125 μm), and large core fiber up to 800 μm.

Optical Input Structure

Fast Sweep
With an advanced monochromator, faster electrical circuits, and noise reduction techniques, the AQ6373E achieves fast measurement speed even when measuring a steep spectrum from DFB-LD signals, or when measuring a low power signal from a broadband light source.

Wide Span Sweep with High Resolution
The 200,001 data sampling points expand measurement range in a single sweep while keeping a high wavelength resolution. This makes your measurements easier and more efficient than conventional systems that use a low number of sampling points and require multiple partial measurements to cover the complete wavelength range.

Easy Accuracy Maintenance
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, the AQ6373E can maintain its high optical performance within a couple of minutes to enable quick-start measurements.

Optical Alignment
Automatically align the optical path in the monochromator using the built-in source to maintain high performance.

Wavelength Calibration
Automatically calibrate the optical spectrum analyzer with an external light source to ensure the wavelength accuracy.

Built-In Optical Alignment Source
An external light source is needed for wavelength calibration. GI 50/125µm fiber required along with periodic calibration. In some instances, the optical alignment and wavelength calibration function cannot correct optical performance.

Easily locate specific files out of thousands in internal and external storage.

USB Ports
Four USB ports facilitate the use of external devices such as a mouse, keyboard, external hard drives, and memory sticks.

Large touchscreen LCD
A responsive high-resolution 10.4-inch multi-touch capacitive touchscreen makes device operation even simpler and more intuitive. Change measurement conditions, perform analysis, and 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.
