 A spectrum analyzer (SPECAN) can be a useful test instrument to troubleshoot a marine VHF radio.  Which of the following is the best procedure to evaluate the input/output stages of a marine VHF transmitter? 
A. Connect the radio to the SPECAN through an in-line attenuator, apply maximum attentuation and set the radio to HIGH power.  Use an inductive probe to evaluate signals at the input/output of AF transmitter stages.
B. Connect the radio to the SPECAN through an in-line attenuator, apply maximum attentuation and switch the radio to HIGH power.  Use an inductive probe to evaluate signals at the input/output of RF transmitter stages.  
C. Connect the radio to the SPECAN through an in-line attenuator, apply minimum attentuation and switch the radio to LOW power.  Use an inductive probe to evaluate signals at the input/output of AF transmitter stages.  
D. Connect the radio to the SPECAN through an in-line attenuator, apply maximum attentuation and switch the radio to LOW power.  Use an inductive probe to evaluate signals at the input/output of RF transmitter stages.
