Technician exam question T0C11
Subelement T0, SAFETY· Group T0C
What is the definition of duty cycle during the averaging time for RF exposure?
- A.The difference between the lowest and highest power output of a transmitter
- B.The difference between the PEP and the average power output of a transmitter
- C.The percentage of time that a transmitter is transmitting (correct answer)
- D.The percentage of time that a transmitter is not transmitting
WhyDuring the averaging time for RF exposure, duty cycle is defined as the percentage of time a transmitter is transmitting. For RF exposure purposes, duty cycle is defined as the percentage of the averaging time that a transmitter is actually transmitting, answer C. It isn't a comparison of power levels (A) or of PEP versus average power (B), and it's the opposite of "time not transmitting" (D), which would describe the complement of duty cycle, not duty cycle itself.
