Samples and Restrictions:

Engineering medical (ISM) equipment and information technology (ITE) equipment

Application:

Used to test EUT radiation emissions.

Test Principle:

CISPR 11, CISPR 32 and other standards, engineering medical (ISM) equipment and information technology (ITE) equipment, the need to open the premises or anechoic chamber 30MHz above the emission test.

Structure:

Main test equipment: receiver, EMI receiving antenna, preamplifier, EMC test software.
Test environment: anechoic chamber (not included in this system, optional, or customer should prepare it)

Use Environment​:

Power supply: 380V ± 10% 50 / 60Hz
Ambient temperature: 5 °C ~ +40 °C, there should be no high concentration of dust, corrosive gas, flammable and explosive objects

Technical Parameters:

Main Test Equipment	Receiver, EMI receiving antenna, preamplifier, EMC test software.
Test Environment	Anechoic chamber
Measuring Distance	It refers to the distance between the point where the EUT is closest to the antenna and the projection of the center of the antenna on the ground. Priority is given to the 10 m method, optional 3 m method
Antenna Height	The height of the antenna from the ground should be varied within the specified range to obtain the maximum reading that would occur when the direct and reflected waves are in phase. For measuring distances ≤ 10 m, the height of the antenna is preferably varied from 1 m to 4 m.
Frequency Range	30MHz-6GHz
