Advantest Q8384 High-End Optical Spectrum Analyzer

Measuring the noise figure of a fiber-optic amplifier The Q8384 improves the noise figure of a fiber-optic amplifier by enhancing the dynamic range, polarization correlation, level accuracy, linearity, and accuracy of wavelength resolution settings.

As well as applying curve fitting and other features, the Q8384 realizes high-precision noise figure measurements at the touch of a button.

Since the Q8384 can accurately determine the ASE signal level of DWDM signals that are multiplexed at 10-minute intervals.

Since the Q8384 can accurately determine the ASE signal level of DWDM signals multiplexed at intervals of 50 GHz (0.4 nm) or narrower, it not only performs accurate noise figure measurements, but it can also accurately measure the noise figure of DWDM signals multiplexed at intervals of 10 minutes.

It not only performs accurate noise figure measurements, but also displays multiple lists of measurement results at the same time.

WDM Analysis Functions

The Q8384 can display up to 256 wavelength peaks and power levels of WDM signals.

It displays the deviation of the wavelength and power level from the ITU-T channel spacing or reference signal as well as the absolute value.

Alternate Scanning Function

The Q8384 can display two sets of measurements under different setup conditions in two windows. These windows are always rewritable using the Q8384's alternate scan feature.

With this feature, users can make detailed measurements of signals in a specific wavelength band while monitoring the entire wavelength region of the WDM system.
