A simple method for fast optical spectroscopy with high resolution is shown. The method is based on the narrowband Brillouin gain process in optical fibers.

A synchronous multi-channel baseband real time spectrum analyzer is proposed in this paper, which can be used for acquisition and analysis of multi-port network signals. The 60MSps ...

Fortunately, dual-purpose analyzers that combine spectrum analysis and VNA are available now, which are designed with a mix ...
