🔍 Key Concepts

• Single Sideband (SSB) voice transmitter modulation and what "two‑tone" testing is used for • The meaning of harmonically related vs non‑harmonically related audio tones • Typical audio frequency range used to modulate an SSB marine transmitter

💭 Think About

• Ask yourself: In a two‑tone test, what is the purpose of using two separate audio frequencies on an SSB transmitter (what are we trying to check about the transmitter)? • Which type of tone relationship (harmonically related or not) will give a cleaner, more representative test of linearity and intermodulation? • Look at each option and ask: Would this kind of signal realistically represent normal SSB voice modulation through the transmitter's audio passband?

✅ Before You Answer

• Verify which options mention non‑harmonically related tones versus harmonically related tones and why that matters for intermodulation tests • Check that the tones are within the audio/modulation passband of a typical SSB marine transmitter (around 300–3000 Hz range) • Eliminate any option that would create an unrealistic or distorted test condition, such as phase tricks or square waves that are not typical of normal SSB voice modulation

What type of signals are used to conduct an SSB two-tone test?

Two audio signals of the same frequency, but shifted 90 degrees in phase.

Two non-harmonically related audio signals that are within the modulation band pass of the transmitter .

Two different audio frequency square wave signals of equal amplitude.

Any two audio frequencies as long as they are harmonically related.
