What signal source is connected to the vertical input of an oscilloscope when checking the RF envelope pattern of a transmitted signal?
Pick an answer to check it.
Answer: D. The attenuated RF output of the transmitter
To view the RF envelope of a transmitted signal, an attenuated sample of the transmitter's RF output is connected to the scope's vertical input. Attenuation protects the scope from full transmitter power.
Tip: Scope sees attenuated RF output.
