CISPR 15 / GB17743: Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment
CISPR 22 / GB9254: Information technology equipment – Radio disturbance characteristics –Limits and methods of measurement
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 |
