Overview
The GTEM-550V 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 turnarounds 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 amplifier output.
Features:
- Ruggedized fully hot galvanized and INOX steel construction
- Unique compact design with new Apex impedance matching transition
- Optimized for EMI and EMC
- Strong fields achieved with low input power
- Broadband line and termination up to 20GHz
- Excellent quality at low cost
