These emissions are generated by the high frequency switching elements used by the isoPower® technology to transfer power through its transformer. The evaluation board is designed to meet the EN55022 Class B emission standard. See the Radiated Emissions Results section for more details. EVALUATION KIT CONTENTS ADM3252E evaluation board GENERAL DESCRIPTION The EVAL-ADM3252EEBZ evaluation board can be used for easy evaluation of the ADM3252E isolated RS-232 transceiver. Screw terminal blocks provide convenient connections for the power and signal connections. Test points are included on the power and signal lines on both sides of the isolation barrier. All required external components are included on the evaluation board. 10897-001 EVAL-ADM3252EEBZ EVALUATION BOARD Figure 1.

Table 3 shows the list of test equipment used. Figure 8 and Figure 9 show the results of the horizontal and vertical scans. Table 4 shows the tabulated results. There were no emissions detected above 1 GHz. 80 70 QUASI PEAK LEVEL (dBµV/m) The EVAL-ADM3252EEBZ evaluation board was tested to EN55022: 2010 (radiated emissions standard). The device was configured and tested with a 3 V, 3.3 V, and 5.5 V dc supply at a data rate of 460 kbps. Each TOUTx pin was loaded with 500 nF of load capacitance and 5 kΩ of load resistance. 60 50 EN55022 40 EN55022 MARKER: 173.5200MHz, 19.1dBµV/m 30 20 10897-009 10 Table 3.
