■特徴／Key Features

While optical spectrum analyzer can only measure power of a modulated signals, Apex Technologies complex spectrum analyzer is able to measure also the optical phase.
The patented method of the AP2441B/AP2443B is based upon a spectral analysis of the optical field, of which the amplitude and the phase of each frequency component are analyzed when all components are spaced by a fixed frequency (Fr1=2.5GHz or Fr2= 625MHz).
By knowing the amplitude and the phase of each spectral component, the temporal variations of the amplitude and the phase are calculated by the Fourier transform, providing the intensity and the chirp or phase as a function of time.

■アプリケーション／Application

Time resolved chirp measurement :
・ Time resolved chirp is an important parameter to predict transmitters performances in a transmission system.
・ AP2441B/AP2443B is the best solution in question of accuracy, repeatability and measurement time, for chirp measurement at high bit rates.
・ Moreover Apex Technologies complex spectrum analyzer can measure the optical pulse shape in the same measurement.
・ For mach-zhender modulator, it is also possible to display the Alfa parameter instead of the chirp.
