What transmitter performance parameter does a two-tone test analyze?

  1. Linearityپاسخ درست
  2. Percentage of suppression of the carrier and undesired sideband for SSB
  3. Percentage of frequency modulation
  4. Percentage of carrier phase shift

توضیح

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.
