4.7.2 Measuring Operation Procedures

a) Turn the standard signal generator output OFF. Leave the equipment under test to be ready for

transmission and verify the transmission with the spectrum analyzer.

b) Set the equipment under test to the receiving state.

c) Turn the standard signal generator ON and leave the equipment under test to be ready for transmission

and verify with the spectrum analyzer that no transmission is being made.
