Swept Spectrum Analyzer (SSA)

Swept Spectrum Analyzer (SSA)


The SSA is a swept spectrum analyzer that measures the transmission spectral response of optical devices.

The principle is to use a linear frequency swept light source to quickly scan the device under test and combine with coherent detection technology to obtain the spectral response of the device under test, then obtain the loss distribution of the device under test at different wavelengths.

It has a built-in swept frequency light source, which can be used to the secondary development of optical measurement and analysis systems. Moreover, additional measurement of optical parameters such as GD, CD, PDL and PMD can be added to the system.
