AQ6380 High Resolution OSA | Yokogawa (2025)

Improve measurement efficiency and productivity

Up to 20x faster measurement

With a new sensitivity mode (RAPID) specialized for CW light, measurement speed is up to 20x faster than conventional models.

New sensitivity settings optimize measurement time

Sensitivity settings have a significant impact on measurement time. The AQ6380 has twomodes and 19 sensitivity settings.Shorten measurement time by selecting the optimum sensitivity according to the type of optical signal and the minimum sensitivity requirement. Measurement sensitivity can also be set numerically. The appropriate sensitivity setting is automatically selected when entering the required minimum sensitivity value.

  • RAPID: Sensitivity mode for fast measurement specialized for CW light
  • TRAD: Traditional sensitivity mode that supports both CW light and pulsed light

Note: The sensitivity is a reference value at 1550 nm, not a guaranteed value

Built-in analysis functions eliminate post-processing tasks

The AQ6380 has built-in analysis functions to characterize optical spectrum from a variety of optical systems and devices includingWDM, DFB-LD, EDFA, and filters. The automatic calculation of the major parameters of the device under test will contributes tofast characterization. Analysis functions include DFB-LD, FP-LD,LED, spectral width (peak/notch), SMSR, optical power, WDM (OSNR), EDFA (NF and gain), filter (peak/bottom), and WDM filter (peak/bottom).

DUT-oriented test apps simplifythe test process

The appplicationmode (APP) transforms an OSA into a versatile 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 worrying with other OSA settings. The AQ6380 comes pre-installed with several standardapplications includingWDM testing, DFB-LD testing, and FP-LD testing. Additional optional applications are available for downloadfrom the Yokogawa Test&Measurement website.

Backward-compatible remote interface for easy upgrade of test system

Easily build an automated measurement system using a remote-control interface (Ethernet or GP-IB). The remote command set conforms to the Standard Commands for Programmable Instruments (SCPI), compatible with AQ6370 series and AQ6319, as well as proprietary AQ6317-compatible commands, allowing for easy upgrades toexisting measurement systems.

OSA Viewer enables emulation and remote control on a PC

Emulate and remotely control the AQ6380 usingOSA Viewer, the application softwareincluded withthe AQ6370 Viewer. OSA Viewer's user interface and analysis capabilitiesallowR&D and production users to easily view and analyze waveforms on theirPC or laptop. The AQ6380 can be controlled remotely via a direct connectionor over anetwork. The screen image fromthe AQ6380 displaysin real time on remotely-connected PCs or laptops, whereyou canoperate it as if you areusing the AQ6380 directly, and data files saved on the AQ6380 are remotely transferable to your computer. These features are ideal when R&D users needto evaluate and analyze measurement data and optimize test conditions and troubleshoot on remotelines, as well as when Production users need to collect and analyze measurement results of remote production lines.

Measurement applications and user-friendly multi-touch operation and connectivity

With over four decades perfecting the user experience, the Precision Makers of Yokogawa Test&Measurement developed the AQ6380 with an easy-to-use front-panel design and intuitive operability.

Large LCD touchscreen

The high-resolution, responsive 10.4-inch multi-touch capacitive touchscreen makes device operation simple and intuitive. Easily change the view and measurement conditions and perform analysis with just a touch. In the optical spectrum view, the waveform view can be zoomed or shifted by a simple tap and drag.

Enhanced function keys

Operability is improved with the addition of frequently-used function keys on the front panel. These include sweep control (Auto/Single/Repeat/Stop), resolution, and sensitivity. The function keys can also be displayed as a pop-up on the screen.

WDM transmission systems

To test a multi-channel, narrowly-spaced WDM system, high-spectral measurement performance is required to test the system’s internal circuit boards (e.g., laser modules, optical transceivers, final output signal). This includes simultaneous peak and OSNR measurements. AQ6380’s wide close-in dynamic range allows accurate OSNR measurement of DWDM transmission systems. 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.

Lasers/optical transceivers

Testing of optical components used in WDM transmission systems such as laser devices, laser modules, and optical transceivers requires high accuracy. Example applications include modulated signal measurement of optical transceivers and transponders and measurement of all channels of optical transceivers with WDM technology beyond 100 G. The AQ6380’s sharp spectral characteristics and high straylight suppression performance enables users to visualize and accurately measure spectral peaks in close proximity.

Passive components (FBG/WSS)

In conjunction with a broadband light sources such as ASE, SLD, or Super Continuum (SC), the AQ6380 enables higher resolution and wider dynamic range measurements and performs evaluation of passive devices including WDM, FBG, ROADM, and WSS. In addition, the built-in optical filter analysis function simultaneously reports peak/bottom wavelength, level, crosstalk, and ripple width.

USB ports

The AQ6380 has USB ports that are compatible with a USB storage device, mouse, and keyboard. The file feature allows users to save data and screenshots to internal memory or USB storage for use in creating test reports. By connecting a mouse or keyboard to the USB port, you can comfortably operate the AQ6380 as if you were operating a PC.

Data access through LAN

The standard LAN port allows convenient access to files stored in the internal memory and enables remote updates for firmware from a PC.
