PAGE 1
Immunity Test System RIS 3000 / RIS 6000 acc. to IEC/EN 61000-4-3 Description The setup of a radiated immunity test system can be done in the conventional way with many separate instruments or in a more comfortable and less risky way with our new EMC control unit, type ECU-3/-6 (please find a detailed description on pages 9 - 13).
PAGE 2
Immunity Test System RIS 3000 / RIS 6000 acc. to IEC/EN 61000-4-3 Control Computer Signal Generator The controller is a standard PC with operating system Microsoft® Windows. Depending on the system layout GPIB (IEEE488) with National Instruments interface card, serial bus RS232, USB and other bus systems are supported. As signal source a commercial signal generator or the built-in signal generator of our EMC test & control unit ECU-3/-6 is used.
PAGE 3
Immunity Test System RIS 3000 / RIS 6000 acc. to IEC/EN 61000-4-3 RF-Power Amplifier The software controls the level of the signal generator output for each test frequency. This signal level is amplified by the power amplifier output in order to generate the required test field strength around the EUT.
PAGE 4
Immunity Test System RIS 3000 / RIS 6000 acc. to IEC/EN 61000-4-3 Function and operation of the test system Homogeneous Field / Uniform Field To assure the reproducibility of the immunity test, the standard prescribes the homogeneity of the field generated. The immunity test system incl. anechoic chamber must guarantee a homogeneous field within a size of 1.5 m x 1.5 m in a distance of 1 m to 3 m from the transmitting antenna, (e.g. Frankonia type AXL-80).
PAGE 5
Immunity Test System RIS 3000 / RIS 6000 acc. to IEC/EN 61000-4-3 RF-Field Strength Meter A field strength meter is necessary for the measurement of the uniform area. It should be of small size in order to avoid disturbances of the field by the physical size of the field strength meter itself. The data transfer from the anechoic chamber to the control room should be via fibre optic link.
