What would be the most likely reason to observe the transmitter output with a spectrum analyzer?

🔍 Key Concepts

• Spectrum analyzer purpose and what it shows on the screen • Difference between measuring modulation characteristics (AM/FM) and measuring unwanted emissions • How spurious emissions appear relative to the main carrier on a frequency spectrum

💭 Think About

• When you look at a spectrum analyzer display, what does each axis represent and what does the tallest peak usually indicate? • Which of the listed measurements normally use specialized modulation meters rather than a spectrum analyzer as the primary tool? • Which choice involves looking for signals at other frequencies besides the main carrier, and how would a spectrum analyzer help with that?

✅ Before You Answer

• Identify which options deal with how the carrier is modulated versus what else is being transmitted besides the carrier • Recall that a spectrum analyzer primarily displays signal power vs. frequency, not time-domain modulation shape • Before choosing, picture the screen: one strong carrier and possible extra small peaks elsewhere — which option best matches that purpose?
