E4B10 : Which of the following methods measures intermodulation distortion in an SSB transmitter?
A
Modulate the transmitter using two RF signals having non-harmonically related frequencies and observe the RF output with a spectrum analyzer
B
Modulate the transmitter using two AF signals having non-harmonically related frequencies and observe the RF output with a spectrum analyzer
C
Modulate the transmitter using two AF signals having harmonically related frequencies and observe the RF output with a peak reading wattmeter
D
Modulate the transmitter using two RF signals having harmonically related frequencies and observe the RF output with a logic analyzer
Correct Answer: Modulate the transmitter using two AF signals having non-harmonically related frequencies and observe the RF output with a spectrum analyzer
