Near Field Probes
A typical emi emission test is performed using broadband EMC antennas such as biconical, log periodics, Combilogs and horns. These antennas usually placed at 1, 3 or 10 meter distance as required by the test specification. These is considered far field measurements and the emission limits are given for the specific distance by the specification. During EMI compliance measurements, the emissions levels from products are compared with these limits. If the product exceeds these limits it is considered failing. These tests are typically conducted in a open area test site IOATS) or inside an anechoic chamber.

Near Field Probes 30 MHz up to 6 GHz
XF1 set
The XF1 set of near field probes consists of 4 passive near field probes and one passive E field probe for making measurements in the development phase of the magnetic and electric fields in ranges from 30 MHz to 6 GHz. Due to their integrated impendance matching, the probes are less sensitive in the lower frequency range than the RF type probes. The probe heads of the XF1 set allow for the step by step identification of interference sources of the magnetic field on an electronic assembly. At first, for example the XF-R 400-1 detects the fields which the assembly emits in total. Next, using higher resolution probes the interference sources can be more precisely detected. The E field probe is used for the detection of electric interfering fields near the assemblies. With trained use of the near field probes, field orientation and field distribution can be detected. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They have an internal terminating resistance.

Test Fixture, Shielding Effectiveness
EM-2108 | 1.5 GHz – 10 GHz
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.
