4. Set up the spectrum analyzer according the frequency setup of the arbitrary
function generator.
5. Set the Ref Level of the spectrum analyzer to 8 dBm.
6. Read the signal level in the Fundamental frequency for each signal. Use this
level as a Reference value in step 7.
7. Verify that the differences between the reference level and the signal level in
the frequency of higher-order at each frequency are below the limit specified
in the following tables.
8. (Two channel models only) Repeat steps 2 through 4 for the channel 2
output.
