  2. Modulate the transmitter using two AF signals having non-harmonically related frequencies and observe the RF output with a spectrum analyzer
  3. Modulate the transmitter using two AF signals having harmonically related frequencies and observe the RF output with a peak reading wattmeter
  4. Modulate the transmitter using two RF signals having harmonically related frequencies and observe the RF output with a logic analyzer
