GTEM 2000 & GTEM 2100
The GTEMCELL GTEM-2000 is a TEM waveguide with the upper-frequency limit extended to the GHz range. It is under consideration as an alternative 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 turn arounds 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 the amplifier output.

TEM Cell (Closed Cell) (Duplicate)
Transverse ElectroMagnetic (TEM) cell or Crawford cell (named after its inventor) is used to generate accurate electromagnetic waves over a wide frequency range: DC (0 Hz) to GHz. EM waves generated in the cell propagate in transverse mode and have the same characteristics as a plane wave. It can be used to calibrate E-field broadband probes for testing radiated E-field immunity as well as for measuring radiated emission from a product with a spectrum analyzer/EMI receiver.

DTEM 6000 Double TEM for Shielding effectiveness
Double Transverse ElectroMagnetic (DTEM) cell or Double Crawford cell (named after its inventor) is used to generate accurate electromagnetic waves over a wide frequency range: DC (0 Hz) to 6 GHz and measure attenuation through materials in a very predictable and accurate way. EM waves generated in the cell propagate in transverse mode and have the same characteristics as a plane wave. It can be used to calibrate E-field broadband probes for testing radiated E-field immunity as well as for measuring radiated emission from a product with a spectrum analyzer/EMI receiver.
TBTC0/1/2/3 - Open TEM Cell for EMC Pre-Compliance Testing
Radiated emission tests are typically carried out in anechoic chambers, using antennas to pick up the radiated signals. Due to bandwidth limitations, several antennas are required to cover the complete frequency range. Furthermore, it requires much space and the cost of the equipment for a standard conformant setup is immense.
TBBT01 High Current Bias-Tee
The TBBT01 Bias-Tee is a device for measuring the saturation effects of power inductors and bias voltage effects on capacitors. The majority of available Bias-Tees for power inductor testing operate at low frequencies, rendering them unsuitable for evaluating decoupling/bias inductors of RF power amplifiers or EMC filters.
TBJT01 Wideband Injection Transformer
The TBJT01 is a wideband injection transformer for control loop stability measurements. It provides galvanic isolation between the swept signal source and the control loop. The injection transformer is internally terminated with a 5 Ohm resistor and protected with a 100 mA fuse. The usable frequency range is 10 Hz to 45 MHz.
TBJT02 Wideband Injection Transformer
The TBJT02 is a wideband injection transformer for control loop stability measurements. It provides galvanic isolation between the swept signal source and the control loop. The injection transformer is internally terminated with a 5 Ohm resistor and protected with a 100 mA fuse. The usable frequency range is 1 Hz to 7 MHz.
