Overview

The GTEM 750 is a TEM waveguide with the upper frequency limit extended to 20 GHz. It is a growing alternative to a measurement facility for both radiated emission and immunity measurements. It is included in the standard IEC 61000-4-20 “Emission and Immunity Testing in Transverse Electromagnetic (TEM)
Waveguides”.

Compared to other measuring methods like EMC test in anechoic chambers or OATS (Open Area Test Sites), GTEM-cells offer some significant advantages for the testing of small and medium sized EUT´s (Equipment Under Test) up to a frequency range of 20 GHz. Quick turnarounds of the EUT as well as numerous testing variations are easy and fast to handle. Switching from emission to immunity testing requires only simple adjustments from receiver input to amplifier output.

Operation

GTEM-cells (Giga-hertz Transversal Electro-Magnetic cells) are waveguide structures intended for electromagnetic compatibility measurements, as well as biomedical applications. The electromagnetic field distribution inside the cell is in TEM mode. With TEM mode propagation, there is no component of electric and magnetic field in the direction of propagation of electromagnetic wave. Therefore the field components are strictly perpendicular. Assuming the field distribution ideal TEM below the cut-off frequency of the cell (before the introduction of higher order modes), the electromagnetic field distribution can be considered static.

Applications

  • EMI and EMS devices
  • Radiation and susceptibility test
  • Specifically designed for telecom application
  • Biomedical and dosimetrical applications
  • Isotropic sensors calibration
  • Receiver sensitivity test
  • Antenna pattern
  • Shielding effectiveness characterization test
