ADM3311E
Figure 31 shows a plot of radiated emissions vs. frequency. This
shows that the levels of emissions are well within specifications
without the need for any additional shielding or filtering compo-
nents. The ADM3311E was operated at maximum baud rates
and configured as in a typical RS-232 interface.
Testing for radiated emissions was carried out in a shielded
anechoic chamber.
