🔍 Key Concepts

• Quieting tests in receiver/audio testing • Purpose and typical features of a SINAD meter • Role of a 1000 Hz bandstop (notch) filter when measuring signal quality

💭 Think About

• Which instrument is specifically designed to evaluate the audio output quality of a communication receiver in terms of signal plus noise and distortion? • Why would a 1000 Hz bandstop filter be useful when you are injecting a 1000 Hz test tone into a receiver to measure how much noise/distortion remains? • Look at each option: which ones are normally associated with RF transmission line measurements or impedance measurements, instead of AF (audio-frequency) performance?

✅ Before You Answer

• Confirm which device commonly has a dB-calibrated AF voltmeter built in for receiver testing • Identify which instrument uses a notch (bandstop) filter at the test tone frequency to remove the main tone and leave only noise/distortion for measurement • Eliminate options used mainly for standing wave/line measurements or impedance/frequency resonance rather than audio quieting tests
