RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

In Part 3 of RF Fundamentals, we will focus on the challenges related to the need to generate and demodulate analog and digitally modulated signals in the RF signal chain. We’ll review CW signal ...

The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and ...

Swept spectrum analyzers can't keep pace with today's RF signals. Gathering RF signal information using realtime approaches is better, but even that is only a beginning. The strength of realtime RF ...

If you’ve ever used an RF signal analyzer, you’re probably used to seeing displays like the spectrum graph or constellation plot. Of course, trusting the answers you get from the instrument often ...
