Question 1 of 27070

A good lab type signal generator for VHF measurements should be able to reduce its output to:

🔍 Key Concepts

• Receiver sensitivity for VHF marine radios (typical microvolt levels) • How low a signal generator output must go to test weak-signal performance • Difference between practical test limits and unnecessarily extreme lab specs

💭 Think About

• What signal strength range do you need from a generator to check whether a VHF receiver can still understand a weak signal? • Among the choices, which value seems low enough to test sensitivity, but still realistic and commonly specified in equipment manuals? • Think about typical sensitivity ratings (in microvolts) you may have seen for marine VHF receivers—how does that compare to these options?

✅ Before You Answer

• Compare each microvolt value with typical VHF receiver sensitivity specs (around a fraction of a microvolt to a few microvolts). • Ask whether the generator should go slightly below the expected sensitivity rating, so you can verify performance at the limit. • Eliminate any value that seems obviously too high to test weak signals or unnecessarily tiny beyond normal test needs.
