The GTEM allows signals to be found that could otherwise be hidden in open field tests due to the plethora of ambient background signals present in our technological society today. GTEM scans are much faster than open field measurements because there is no need to determine if the signal being measured is a signal from the DUT or from those normally present in the environment. The increased speed is also due to not having to position a measurement antenna, and the use of peak detection mode for most measurements. With the GTEM as many as 12 scans can be performed in an hour. This allows various configurations of the Device Under Test to be evaluated in a short time. Radiated emission scans are normally performed from 30 to 1030 MHz., but can be performed from 10 kHz. to 6 GHz. Radiated Susceptibility tests are also well suited to the use of the GTEM test chamber
Any signals too close or over the limit can be spot checked using a highly accurate Rhode & Schwartz measurement receiver set to Quasi-Peak detection mode.
Conducted scans from .15 to 30 MHz. are performed in a shielded room on 115VAC single phase Hot & Neutral
conductors. All scans are plotted and limit lines are included.
EMC mitigation assistance is available if desired.
ESD, Surge, Frequency Stability with Temperature and a few other investigative tests can be performed.
Radiated Emission above 6 GHz is preformed with a Horn Antenna spaced one meter from the DUT. The Horn Antenna is connected to an EMC60 microwave measurement receiver which measures the average signal strength.
