Lower levels of radiated EMI noise can be measured by using a high gain antenna.
Application
By using a high gain antenna, lower levels of noise can be measured in radiated EMI (emission) measurements.
Solution
Measurement examples with Handheld signal analyzer MSA538E + PC software for EMI MAS530 are shown.
Antenna MAN150B and MAN150 that have different gain were used in the measuerments.
We input a weak noise-level signal of 50 MHz and compared the peak of it (upper).
The measurement results without signal input are also shown to compare the noise floor (bottom).
☆The MAN150B (Large gain) has a lower noise floor so you can clearly see the 50 MHz peak.
