IV. Section 15.207: Power Line Conducted Emissions for AC Powered Units

4.1 Test Condition & Setup

The power line conducted emission measurements were performed in an anechoic chamber.

The EUT was assembled on a wooden table, which is 80 centimeters high, was placed 40 centimeters

from the backwall and at least 1 meter from the sidewall.

Power was fed to the EUT from the public utility power grid through a line filter and Line

Impedance Stabilization Networks (LISNs). The LISN housing, measuring instrumentation case,

ground plane, etc., were electrically bonded together at the same RF potential. The Spectrum

analyzer (or EMI receiver) was connected to the AC line through an isolation transformer. The

50-ohm output of the LISN was connected to the spectrum analyzer directly. Conducted emission

levels were in the CISPER quasi-peak and average detection mode. The analyzer's 6 dB bandwidth

was set to 9 KHz. No post-detector video filter was used.

The spectrum was scanned from 150 KHz to 30 MHz. The physical arrangement of the test

system and associated cabling was varied (within the scope of arrangements likely to be encountered

in actual use) to determine the effect on the unit's emanations in amplitude and frequency. All

spurious emission frequencies were observed. The highest emission amplitudes relative to the

appropriate limit were measured and have been recorded in paragraph 2.4.

There is a test condition apply in this test item, the test procedure description as <1.3>. Three

channels were tested, one in the top (CH01), one in the middle (CH06) and the other in bottom

(CH11).
