Test odolnosti proti radiačnímu elektromagnetickému poli (EMS) a emisního limitu (EMI) v komůrce článku GTEM

GTEM (Gigaherz Tanseverse Electromagnetic) Cell Test Chamber is a new type of electromagnetic compatibility test equipment developed based on the TEM Cell Chamber (it applies asymmetric rectangular structure to simulate free space to generate TEM electromagnetic waves inside the small chamber). Using GTEM transverse electromagnetic wave transmission chamber to perform EMC performance testing is a new measurement technology developed in the EMC field in recent years.

Due to the high broadband performance of GTEM (from DC to microwave), it can be used for RF Electromagnetic Field Radiation Immunity (EMS) testing and RF Electromagnetic Field Radiation Emission Limit (EMI) testing. Compared with various test chambers, shielded rooms, anechoic chambers and open-air test fields, GTEM Test Chamber haS simple structures, low costs, easy and fast, and automatic control tests, and have been highly praised and recognized by many famous third laboratories.

Intenzita elektrického pole ve středu gigahertzové příčné elektromagnetické je:
E: Vertikální složka síly elektromagnetického pole
Po: Vysokofrekvenční energie přiváděná do Hertzovy transverzální elektromagnetické komory
Rc: Impedanční charakteristika gigahertzové příčné elektromagnetické komory
d: Svislá vzdálenost mezi základní deskou a horní / dolní deskou
Lze vypočítat větší hodnotu intenzity pole podle velikosti mezi deskou jádra a horní / dolní spodní deskou komory Hertzovy příčné elektromagnetické vlny ve vzorci.

PS Due to the size limitation of container, GTEM-2 a GTEM-4 can be transported as assembled units in 40HQ container, but GTEM-6 a GTEM-8 need to be assembled on site.

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

2. GTEM used for RF Electromagnetic Field Radiation Emission Limit (EMI) Pre-Compliance Test (LISUN Model: GTEM-EMI):
GTEM chamber with LISUN EMI-9KC Systém přijímače EMI (R&S or PMM receiver system is also optional) to perform RF Electromagnetic Field Radiation Emission Limit (EMI) Pre-Compliance Test according to IEC61000-4-20, CISPR11, CISPR14, CISPR20, CISPR22 and CISPR25. By simulating free space and open field test conditions, using mathematical modeling and three-dimensional data acquisition and calculation methods, it provides economical, convenient and feasible solutions for the electromagnetic compatibility EMI testing of small-sized electronic and electrical products for the majority of corporate users. The Pre-Compliance Test approach can effectively evaluate the impact of electronic equipment on the electromagnetic environment.
