Which of the following test instruments is used to display spurious signals and/or intermodulation distortion products generated by an SSB transmitter?

Erklärung

Spurious outputs and intermodulation products sit at frequencies away from the wanted carrier, so finding them requires an amplitude-versus-frequency display. A logic analyzer works on digital states and a network analyzer characterizes a device's response to its own stimulus, neither of which shows a transmitter's output spectrum.
