What transmitter performance parameter does a two-tone test analyze?
Linearity✓Richtige Antwort
Percentage of suppression of the carrier and undesired sideband for SSB
Percentage of frequency modulation
Percentage of carrier phase shift
Erklärung
Two tones through a perfectly linear transmitter come out as just those two tones, so any additional products in the output are created by nonlinearity in the amplifier chain. Measuring the level of those products relative to the tones is a direct measure of linearity.
