Modulation bandwidths continue to grow, promising higher data rates yet imposing test difficulties. Most test technologies are still rooted in past, narrowband architectures, which are increasingly ...

Directly modulated semiconductor lasers represent a crucial technology in modern optical communications, where the injection current is directly varied to encode information onto the laser output.

Because the technique provides such significant benefits, and because the transitions (phase changes, chemical reactions, etc.) observed in a sample as it is heated are often very complex, the ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
