What type of equipment is commonly used for radio frequency (RF) measurements?

Spectrum analyzers are specifically designed for measuring and analyzing the frequency spectrum of radio frequency (RF) signals. They provide detailed information about the amplitude and frequency of signals, allowing users to observe the characteristics of RF emissions, identify interference, and ensure compliance with communication standards. This capability is essential in tactical communications, as it helps in assessing the performance of RF circuits and systems.

While oscilloscopes are great for time-domain signal analysis, they do not provide the frequency-domain insights that spectrum analyzers do. Multimeters, on the other hand, are primarily used for measuring voltage, current, and resistance rather than RF signals. Signal generators are used to produce RF signals rather than measure them. Therefore, in the context of RF measurements, spectrum analyzers are the most appropriate and versatile tool.
