  • Description
  • GTEM (Gigaherz Tanseverse Electromagnetic) Test Chamber is a new type of electromagnetic compatibility test equipment developed on the basis of the TEM chamber (it application asymmetric rectangular structure to simulate free space to generate TEM electromagnetic waves inside the small chamber). By use of GTEM transverse electromagnetic wave transmission chamber for EMC performance test is a new developed measure technology in the EMC field in recent years.

    Due to the high wide-band performance of GTEM (from DC to microwave), it can be used for RF Electromagnetic Field Radiation Immunity (EMS) test, and it can also be used for RF Electromagnetic Field Radiation Emission Limit (EMI) test. Comparing to various test chambers, shielded room, anechoic chamber and open test fields, the GTEM Test Chamber is simple, low cost, easy for fast and automatic control test, it has been highly valued and accepted by many famous third lab.

    GTEM Cell Test Chamber Structure Diagram

    The electric field intensity at the center of the gigahertz transverse electromagnetic is:
    E: Vertical component of electromagnetic field strength
    Po: RF power fed to the Hertz Transverse Electromagnetic Chamber
    Rc: Impedance characteristic of gigahertz transverse electromagnetic chamber
    d: The vertical distance between the core board and the upper / lower boards
    It can be calculate larger field strength value according to the size between the core plate and the upper / lower bottom plates of the Hertz transverse electromagnetic wave chamber in the formula.

    P.S. Due to the container size limit, the GTEM-2and GTEM-4 can be delivery as an assembly unit via 40HQ container. But the GTEM-6 and GTEM-8 need to be assembly in the customers’ site.

    1. GTEM uses for RF Electromagnetic Field Radiation Immunity (EMS) Full-Compliance Test (LISUN Model: GTEM-EMS):
    GTEM-2 work with Signal Generator, Power Meter, Field Strength Probe / Monitor and Power Amplifier is  fully meet standard IEC61000-4-3, IEC61000-4-20, GB/T17626.3 and GB/T17215 standards to use for RF Electromagnetic Field Radiation Immunity (EMS) Full-Complaince Test. This system has been widely used in electric power, communication, military industry, quality inspection and other fields, and has established a powerful test basis for evaluating the susceptibility of small electronic equipment to radiated electromagnetic field interference.
