GTEMCELL GTEM 250 and GTEM 250 SAE

Meets IEC/EN 61000-4-20, SAE J1752/3, IEC 62132-2 and IEC 61967-2

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 absorbers to achieve a 50 Ohm broadband match. It is applied for Measuring of Emission, Radiated, radio frequency field-immunity test.

Model GTEMCELL 250 with Ferrite tiles on the bottom offers a wider operating bandwidth  with peack smoothed and flat response starting from DC to microwave frequencies. It is a indispensable tools for reaserchers and developers engineers!

Model GTEMCELL 250 SAE includes a special opening to test integrated circuits, dimensions: 80 mm x 80 mm on Approx. 45 mm septum height, closed from a removable panel where are placed the IC under testing.

The standards SAE J1752/3 and IEC 61967-2 defines a method for measuring the 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.
