🔍 Key Concepts

• Purpose of routine radar servicing and troubleshooting • Which instrument lets you see waveforms and pulses in an electronic circuit • Difference between measuring power, frequency, audio vs. actually viewing signal shape and timing

💭 Think About

• When a radar technician is trying to diagnose a problem in the transmitter/receiver, what kind of information about the signal is most important to see directly? • Which of these tools would best let you examine the shape, timing, and relative amplitude of radar pulses? • For aligning and checking timing in radar circuits, which tool on the list is normally connected to test points to view the signal?

✅ Before You Answer

• Identify which instrument is used to display electrical signals over time on a screen • Eliminate tools that mainly measure only a single number (like power level or frequency) rather than show a changing waveform • Think about which instrument is standard on the bench of almost every electronics service technician for troubleshooting complex circuits
