Shielding performance of average to 80 dB from 0.3 GHz to 18 GHz. Table top outer dimensions 752mm x 1362mm x 732mm (LxWxH). T-Series EMC Tent : flexible table solution for small DUTs Shielding from average to 95 dB from 0.3 GHz to 18 GHz. People’s tents, outer dimensions 2150 mm x 2150 mm x 2180 mm (LxWxH). P-Series EMC Tent : compact and accessible All tents are suitable for clean rooms up to A300 / class 1,000. This flexibility is ideal for in-house pre-compliance testing. Susceptibility, on the other hand, describes the resistance of a device under test to interference from other devices. Interference emission refers to the undesirable property of affecting other equipment by electromagnetic radiation. With these Faraday EMI tents, any room can be converted into a measurement laboratory in a short period of time and with little effort. EMC is achieved by testing for electromagnetic susceptibility (EMS) and electromagnetic interference (EMI). A tent is made up of several layers for the best measurement result, but also to guarantee functionality and thus create a robust, tear-resistant and practical workable solution. ![]() This base material can be optimized to the desired radiation attenuation and frequency range. Product developers or designers use many non-compliant EMC test setups during their works but these measurements are not for product certification.The Shieldex EMI tents are made of self-produced yarns and textiles. Such non-compliant test setups may also give you non-accurate test results. If your test equipment does not comply with CISPR 16, it is not possible to perform product compliance or certification testing. Limited test spaces are also creates electromagnetic interactions between test setups and these interactions might adversely affect the test/measurement results.Ĥ) Non-compliant test setups: Non-compliance means the test setup deviates from the EMC test standards and their required parameters. If your test space is smaller than mentioned dimensions or does not fulfil performance validation criteria, test results would be inaccurate. The most popular test site compliance standard is CISPR 16 series standards. If your RF signal generator is able to generate RF signals between 200-1000 MHz, you cannot use it for testing 80-200 MHz frequency range.ģ) Limited test spaces: For proper, accurate and full-compliance EMC testing, test sites used during EMC tests should be compliant with the EMC standards. If you have no RF absorbing materials on inner walls of your RF shielded room, it is not possible to proper radiated RF immunity testing over 30 MHz. If you have an EMI receiver which is able to measure emissions between 30 MHz to 1 GHz, it is not possible to measure 1-6 GHz frequency range. EMC lab’s frequency range is limited by its test site, test equipments and any accessories used on these test setups. Operating an high-current EUT on such immunity test instruments which has low current limits is not possible.Ģ) Limited frequency range: Conducted emissions, radiated emissions, conducted RF immunity, radiated RF immunity, magnetic field emissions, magnetic field immunity tests are different EMC tests to check EUT at different frequencies. ![]() ![]() Performing EMC immunity tests on power lines require signal generators and CDNs which are limited by currents mentioned on their datasheets. Most of the EMC test laboratories missing new opportunities to test high current drawing EUTs due this reason. It is not possible to test high current EUTs at those facilities whose current capacity is under the EUT’s maximum current. 16 Amps and 32 Amps current limits are so popular due to power filters used at EMC test facilities. 1) Limited current capacity: EMC lab’s capability is limited by the Equipment Under Test (EUT) that can be tested. ![]()
