Lower levels of radiated EMI noise can be measured by using a high gain antenna.<\/p>\n\n\n

Application<\/h2>\n

By using a high gain antenna, lower levels of noise can be measured in radiated EMI (emission) measurements. <\/p>\n\n\n\n

Solution<\/h2>\n

Measurement examples with Handheld signal analyzer MSA538E + PC software for EMI MAS530 are shown.
\nAntenna MAN150B and MAN150 that have different gain were used in the measuerments.
\nWe input a weak noise-level signal of 50 MHz and compared the peak of it (upper).
\nThe measurement results without signal input are also shown to compare the noise floor (bottom).<\/p>\n

\u2606The MAN150B (Large gain) has a lower noise floor so you can clearly see the 50 MHz peak.<\/p>\n\n\n\n
