2.3 Radiated & Conducted Emissions Test Site Description

2.3.1 Semi-Anechoic Chamber Test Site

The EMC radiated test facility consists of an RF-shielded enclosure. The interior dimensions of the
indoor semi-anechoic chamber are approximately 48 feet (14.6 m) long by 36 feet (10.8 m) wide
by 24 feet (7.3 m) high and consist of rigid, 1/8 inch (0.32 cm) steel-clad, wood core modular panels
with steel framing. In the shielded enclosure, the faces of the panels are galvanized and the
chamber is self-supporting. 8-foot RF absorbing cones are installed on 4 walls and the ceiling. The
steel-clad ground plane is covered with vinyl flooring.

The turntable is driven by pneumatic motor, which can support a 2000 lb. load. The turntable is
flush with the chamber floor which it is connected to, around its circumference, with a continuous
metallic loaded spring. An EMCO Model 1060 Multi-device Controller controls the turntable
position.

A pneumatic motor is used to control antenna polarizations and height relative to the ground. The
height information is displayed on the control unit EMCO Model 1050.

The control room is an RF shielded enclosure attached to the semi-anechoic chamber with two
bulkhead panels for connecting RF, and control cables. The dimension of the room is 7.3 m x 4.9
m x 3 m high and the entrance doors of both control and conducted rooms are 3 feet (0.91 m) by 7
feet (2.13 m).

The power line conducted emission site includes two LISNs: a Solar Model 8028-50 50 Ω/50 μH and an EMCO Model 3825/2R, which are installed as shown in the figure below. For evaluations requiring 230 V, 50 Hz AC input, a Polarad LISN (S/N 879341/048) is used in conjunction with a California Instruments signal generator Model 2001RP-OP1.

7.3.4 Sample Calculation
RC = RU + CFT

Where:
CFT = Total Correction Factor (AF+CA+AG)-DC (Average Measurements Only)
RU = Uncorrected Reading
RC = Corrected Level
AF = Antenna Factor
CA = Cable Attenuation
AG = Amplifier Gain
DC = Duty Cycle Correction Factor

Example Calculation: Peak
Corrected Level: 29 + 10.17 = 39.17 dBµV/m
Margin: 115.8 dBµV/m – 39.17 dBµV/m = 76.63 dB

Example Calculation: Average
Corrected Level: 26.3 + 10.17 – 0 = 36.47dBµV/m
Margin: 95.8 dBµV – 36.47 dBµV/m = 59.33 dB
