Measuring Fundamental Amplitudes
5.Set the EMC analyzer center frequency to the Fundamental Frequency listed in Table
6.Set the microwave spectrum analyzer controls as follows:
SPAN ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: : 100 kHz
REFERENCE LEVEL ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: +5 dBm
ATTEN ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: 20 dB
LOG dB/DIV : ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: 10 dB
7.Set the microwave spectrum analyzer CENTER FREQUENCY to the Fundamental Frequency listed in Table
8.On the microwave spectrum analyzer, press PEAK SEARCH. If the marker frequency is greater than 2.5 GHz, press PRESEL PEAK and wait for the PEAKING! message to disappear. Press MARKER !REF LVL. Wait for another sweep to nish.
9.Record the microwave spectrum analyzer marker amplitude reading in Table
10.Repeat steps 5 through 9 for all Fundamental Frequency settings in Table
