GTEM 400 – 450 – 450V

The GTEM cell is, in principle, a tapered coaxial line (offset septum plate), which is terminated by a hybrid combination of discrete resistors and RF absorber to achieve a 50 Ohm broadband match. It is applied for the measure of Radiated emissions and radiofrequency field-immunity tests. The GTEMCELL GTEM 400 family consists of the: GTEM-400 is made with 65cm pyramidal carbon-foam absorbers (RAM). GTEM-450 is made with 51cm. EMC Truncated pyramidal absorbers (RAM) GTEM-450V is the vertical model (suffix V) made with 51cm. EMC Truncated pyramidal absorbers (RAM)

Model GTEMCELL GTEM250 F with Ferrite tiles on the bottom offers a wider operating bandwidth with peak smoothed and flat response starting from DC to microwave frequencies. It is an indispensable tool for researchers and developers engineers!


The standards SAE J1752/3 and IEC 61967-2 define a method for measuring electromagnetic radiation from an integrated circuit (IC). The IC itself is mounted on a test board on a panel that is clamped in the upper face close to the top of the GTEM cell. The test board becomes a part of the cell wall. A receiver or spectrum analyzer measures the RF emissions emanating from the integrated circuit and impressed onto the septum of the cell. The standard IEC 62132-2 defines the immunity test set-up on integrated circuits tested with a GTEM.

The GTEMCELL GTEM250 AF-V is a vertical stand-alone solution for space-saving in the test lab area with a maximized EUT test volume. The GTEM 250AF-V is the ideal TEST CELL FOR ELECTROACOUSTICS -HEARING AIDS according to IEC 60118-13 and others. Many options are available including the XYZ manipulator.
