Using A Tracking Generator

Many spectrum analyzers include tracking generators, but some new engineers my not completely understand what the purpose is and how they can help with certain measurements. In a nutshell, tracking generators are variable, or swept, RF generators that “track” with the spectrum analyzer sweep frequency. Some tracking generators have a limited frequency sweep as compared with their mating spectrum analyzer, so you need to know any frequency limitations in advance. In this article, I’ll use the new Rigol DSA815TG and the built-in tracking generator to measure a 150 MHz bandpass filter and a 10 dB attenuator. More…
