Reliant EMC

GTEM Cell 250 FROM GTEM ITALIA

GTEM 250 and GTEM 250 SAE GTEM Cells
For emission and immunity testing according to IEC/EN 61000-4-20
GTEM 250 from GTEM Italia
The GTEM 250 and GTEM 250 SAE GTEM Cells meet IEC/EN 61000-4-20, SAE J1752/3, IEC 62132-2 and IEC 61967-2 standards.
 
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.

GTEM 250
Model GTEM CELL 250 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!

GTEM 250 SAE
Model GTEM CELL 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.

GTEM Italia GTEM 250 SAE Option

 
Both the GTEM 250 and GTEM 250 SAE GTEM Cells can be ordered in a Vertical orientation!!!
Great Space Savings orientation!

The standards SAE J1752/3 and IEC 61967-2 define 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.
