🔍 Key Concepts

• CDMA modulation and how it spreads power over time and frequency • How analog RF power meters (like simple wattmeters) detect and display power • Difference between instantaneous power, average power, and peak envelope power (PEP) in RF measurements

💭 Think About

• Think about whether an analog power meter can follow rapid power fluctuations that occur in complex digital modulations like CDMA. • Ask yourself: does CDMA produce a constant carrier like traditional analog AM/FM voice, or does the signal vary in a way that might confuse a simple analog meter? • Consider what would make a statement about power measurement obviously impossible or exaggerated, versus just describing a limitation of the instrument.

✅ Before You Answer

• Verify whether CDMA signals have relatively constant average power but highly variable instantaneous power. • Check how a typical analog in‑line wattmeter works: is it calibrated for steady carriers or for complex digital modulation? • Eliminate any option that claims something is completely impossible if you know power can always be measured in some way.
