EMC Question of the Week: September 9, 2024
During an immunity test, the field strength measured inside a test chamber is 160 dB(μV/m). After the test equipment is powered down, the measured field strength due to the EUT is 40 dB(μV/m). So, powering down the test equipment reduced the measured field strength by,
- 160 dB(μV/m)
- 120 dB(μV/m)
- -120 dB(μV/m)
- 40 dB(μV/m)
