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

Ambient condition change, vibration and shock to an optical precision product, like an optical spectrum analyzer, will affect 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.
The 735385 NA Conversion Adapter is the accessory for the AQ6370 series/AQ6361/AQ6360 optical spectrum analyzer.
NA conversion adapters can be connected to GI50 or GI62.5 optical fibers with relatively large NA to improve the stability of light level measurements.
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.
