4.4 Conducted Spurious Emissions
Using the test setup shown in Figure 4.1, the spectrum outside of the specified channel
was observed and the data was recorded on all products above the 70-dB noise floor of
the spectrum analyzer. This data is shown in Table 4-6 and is presented as graphs in
Figures 4-9 and 4-10.
