Yokogawa spectrometer AQ6370E-10/20

   Which spectrometer simple operation, easy maintenance, the use of a diffraction grating spectral measurement, covering the wavelength range 600 ~ 1700nm, wavelength resolution between 0.02 ~ 2.0nm, minimum receiver sensitivity of-90dBm, and rely on proprietary technology Yokogawa 100nm scan completed within 0.2 seconds.

  Its flexibility in parameters’setting and its unmatched performance make

The AQ6370D model the best choice for R&D and Production of optical  communication devices.

  Discovering the characteristics of the AQ6370E-10

  Wavelength range:600 to 1700 nm

With its broad wavelength range coverage,AQ6370D is suitable to test devices designed for single-mode as well as multimode transmissions.

  Standard- and high-performance model

There are two models available ,with high performance model providing even higher wavelength accuracy and dynamic range.

  7 wavelength resolution settings:from 20pm to 2nm

To enable the user to choose the best value according to the characteristics of the DUT.

  7 level sensitivity settings:down to -90dBm

To enable the user to choose the best value according to test applications and measurement speed requirements.

  High close-in dynamic range :78dB typ.

With sharp spectral characteristics of the AQ6370D monochromator,signals in close proximity can be clearly separated and accurately measured.

  Fast measurement:only 0.2 sec for 100 nm span

With sensitivity set to NORM_AUTO(-70dBm).

  Double Speed mode

Lncreases the sweep speed up to 2 times compared to the standard sweep mode,with only a 2 dB penalty on the standard sensitivity value.

  High wavelength accuracy:±0.01nm

Easily maintained thanks to the built-in Cailbration function and wavelength reference source(optional).

  High straylight suppression ratio:80 dB typ.

The AQ6370D monochromator is specifically designed to offer excellent stray-light suppression capability without using the High Dynamic Mode setting which could increase the measurement time substantially when activated. Moreover, the AQ6370D is the first and only OSA in the world to guarantee the straylight suppression ratio specification.

  Littrow light cancellation

The Littrow light is an artifact caused by a strong signal peak and appears at awavelength about 200 nm below the actual signal peak. The advanced monochromator used in AQ6370D reduces the Littrow light appearance.

  APC connector Level Correction function

Corrects the level offset caused by the higher inseryion loss of Angled PC connectors.

  Data Logging function

Records analysis results such as WDM analysis(OSNR,optical signal/noise ratio), distributed feedback laser diode (DFB-LD)analysis, and multi-peak measurement at up to 10,000 points per channel with time stamps .Recorded data can be displayed in table and graphical forms. This function is useful for the long-term stability testing and temperature cycle testing of systems and devices. The optical spectrum of each measurement can also be stored for reviewing and troubleshooting.

  Advanced Marker function

Adds markers to obtain the power density and the integrated power of a designated spectrum. This new feature makes it easy to get an OSNR value of the signal, whether modulated or not, directly from its spectrum.

  Gate Sampling function

Facilitates the recirculating loop testing of optical transmission systems. Using an external gate signal, the AQ6370D obtains the optical spectrum of the signal which is passing through a certain loop.

  Resolution Calibration function

Calibrates 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.
