unmodulated.
3) Slowly increase the amplitude of the signal generator until the value indicated
on Spectrum Analyzer/EMI Receiver #1 reaches the appropriate amplitude
(see section 6.2).
4) Record the present frequency and the measured forward power value
indicated on Spectrum Analyzer/EMI Receiver #2.
5) Set the frequency of the signal generator and measurement equipment to the
next test frequency (see section 6.1).
6) Repeat Steps 3-5 until all test frequencies have been calibrated.
