DUT-oriented test apps (APP) simplifies the test process

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.

DUT-oriented test apps (APP) simplifies the test process

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.

Gate sampling function

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.

Resolution calibration 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

OSA Macro Program Function

The OSA Macro Program Function enables automated measurement by creating programs for entry of measurement conditions and other tasks. Users can program a sequence of measurement procedures from entry of measurement conditions (e.g., wavelength sweep width, setting resolution) to analyses, data saving, output, and others and eliminates redundant procedures on the production line. The function acts as a controller of other connected devices through the LAN or RS232C port and allows users to build an automatic measuring system without using an external PC and input measurement conditions or output measured results while programs are running.
