Which of the following is an advantage of using an antenna analyzer compared to an SWR bridge?

An antenna analyzer is a highly versatile piece of test equipment that typically contains a low-power RF generator, a frequency counter, and an SWR bridge. Unlike a standalone SWR bridge that requires manual transmitter keying and only shows the forward/reflected power ratio, an analyzer calculates and directly displays SWR, complex impedance, and other parameters across a range of frequencies without needing a separate transmitter. Distractor A is incorrect because analyzers are diagnostic tools; they measure but do not mechanically or electrically tune the antenna for you. Distractor C describes the function of an oscilloscope, not an antenna analyzer.
