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.

Testing for radiated emissions was carried out in a shielded

anechoic chamber.
