Question 1 of 27070

Q

The follow devices that could be used to indicate oscillation in a crystal oscillator are:

🔍 Key Concepts

• How a crystal oscillator works and what it means for it to be "oscillating" • Different types of indicators (meters, bulbs, frequency meters) and whether they can respond to RF (radio frequency) or just DC • Which of the listed devices can show presence of RF energy or oscillation rather than just DC current

💭 Think About

• For each option, ask: would this device change noticeably when RF oscillations are present, or does it only show a steady DC value? • Think about which devices are specifically used in radio practice to check for RF output or frequency of a transmitter or oscillator. • Consider if some of these devices can give only a rough indication of oscillation while others give a more precise or indirect indication.

✅ Before You Answer

• For each device listed, verify: can it be used (even crudely) to indicate RF oscillation in a nearby circuit, or only DC conditions? • Identify which option(s) include at least one device that is definitely used in RF work to detect or measure oscillations (e.g., frequency meters, wavemeters). • Before choosing, check whether every single device in an option can plausibly indicate oscillation in some way, even qualitatively.
