What test instrument can be used to display spurious signals in the output of a radio transmitter?

🔍 Key Concepts

• Purpose of spurious signal measurements in radio systems • What each instrument primarily measures or displays: frequency content vs. power vs. reflections vs. logic states • How unwanted emissions away from the main carrier frequency are normally observed in a lab or test bench

💭 Think About

• Which instrument is specifically designed to show how signal power is distributed across different frequencies? • Which choices are mainly for measuring total power, digital signal states, or cable faults rather than detailed frequency content? • If you needed to verify that your transmitter was not radiating on unintended side frequencies, which tool would let you see those extra frequencies visually?

✅ Before You Answer

• Identify which option can show signal strength as a function of frequency (not just total power or time). • Eliminate any instruments that are mainly used for digital logic troubleshooting or transmission line fault location. • Confirm which device is standard for checking unwanted emissions and harmonics of a transmitter.
