Figure 35 shows a plot of radiated emissions vs. frequency. The
levels of emissions are well within specifications, without the
need for any additional shielding or filtering components. The
ADM2xxE were operated at maximum baud rates and
configured like a typical RS-232 interface.
Testing for radiated emissions was carried out in a shielded
anechoic chamber.
