B.17.
4) The signal power was measured using the peak frequency scale and recorded in the auxiliary table
B.17.
5) The same signal power is measured using a power meter and recorded in the auxiliary table B.17.
6) Set the test frequencies in sequence to complete the test.
d) Test record and data processing
The magnitude error ΔA of the corresponding frequency point is calculated according to Equation (10)
and recorded in the auxiliary Table B.17.
The largest absolute value of the calculated value, ΔA, is
recorded as the magnitude accuracy in the functional performance test record table A.1.
