Figure 34. Radiated Emissions Test Setup
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.
START 30.0MHz
STOP 200.0MHz
