Test Cell for Electroacoustics - Hearing Aids IEC 60118-13

GTEM 250zoom
  • Vertical solution for space saving
  • Meets IEC/EN 61000-4-20, IEC 60118-13 and others
  • For 100 Watts input power
  • Excellent VSWR up to 18 GHz

A GTEM (Gigahertz Transverse Electro Magnetic) cell is a test site for efficiently performing both radiated immunity and emissions testing in a single, controllable and shielded environment. Compared to other test sites, GTEM testing is faster with high accuracy and excellent reproducibility.

In principle, the GTEM cell is a coaxial line expanding pyramidally and having an impedance of 50 Ω. At its end, the line is terminated by a combination of termination resistors and RF absorbers designed and constructed to match the above mentioned impedance.

Teseq offers with GTEM 250A a cell with excellent VSWR for improved testing in the entire frequency. The version V allows the vertical and space saving positioning on a desktop. The GTEM 250A-V is ideal for testing on electroacoustics - hearing aids as given in IEC 60118-13 because of the excellent parameters and option for XYZ manipulator.
