Q

What does the horizontal axis of a spectrum analyzer display?

🔍 Key Concepts

• Spectrum analyzer axes and what each represents • Difference between frequency and amplitude/voltage in signal displays • How an oscilloscope display compares to a spectrum analyzer display

💭 Think About

• Think about what information a radio technician usually wants to see spread out along the bottom (horizontal) of the screen when checking a transmitted signal. • Ask yourself: is a spectrum analyzer showing how a signal changes over time, or how a signal’s strength is distributed over some other quantity? • Compare: on an oscilloscope, the horizontal axis is typically time. On a spectrum analyzer, what is varied or ‘swept’ instead of time?

✅ Before You Answer

• Be clear on the difference between time-domain and frequency-domain displays. • Identify which quantity is being swept across the screen from left to right on a spectrum analyzer. • Confirm which measured quantity is usually shown on the vertical axis instead, so you don’t mix the two up.
