  • Alternative to GTEM cell
  • Radiated emissions (EMI): Pre-compliance by the CISPR 25 method
  • Radiated immunity (EMS): Pre-compliance by the IEC/EN 61000-4-3 and DIN/ISO 11452-2 method
  • Compact chamber design and adapted hybrid absorber lining with Frankosorb®
  • Turn-key solution

The UCC is Frankonia’s alternative solution to the GTEM cell for pre-compliance testing as well as for research and science purposes. The most important advantages of the UCC is that the test engineer is able to enter the chamber, which allows for an easier, better and even larger EUT setup. The ultra compact chamber solution is designed for pre-compliance radiated emission and immunity tests, conducted tests, and pre-compliance tests for automotive components by the CISPR 25 method.

EMC means "an electronic or electrical product shall work as intended in its environment. The electronic or electrical product shall not generate electromagnetic disturbances (interference), which may influence other products". In other words, EMC deals with problems of noise emission as well as noise immunity of electronic and electrical products and systems. Electromagnetic disturbances occur as conducted interference as well as radiated emissions and immunity problems.

An anechoic chamber is a room designed to completely absorb reflections of electromagnetic waves used for various EMC Testing. They are also insulated from exterior sources of noise. The combination of both aspects means they simulate a quiet open-space of infinite dimension, which is useful when exterior influences would otherwise give false results. The RF anechoic chamber is typically used to house the equipment for performing measurements of antenna radiation patterns, electromagnetic compatibility (EMC) and radar cross section measurements. EMC chambers allow for the performance of fast and efficient EMC radiated tests at a convenient location, without interference from the ambient electromagnetic environment.

The term conducted emissions refers to the mechanism that enables electromagnetic energy to be created in an electronic device and coupled to its AC power cord. Similarly to radiated emissions, the allowable conducted emissions from electronic devices are controlled by regulatory agencies. If a product passes all radiated emissions regulations but fails a conducted emissions test, the product cannot be legally sold.

The term radiated emissions refers to the unintentional release of electromagnetic energy from an electronic device. The electronic device generates the electromagnetic fields that unintentionally propagate away from the device’s structure. In general, radiated emissions are usually associated with non-intentional radiators, but intentional radiators can also have unwanted emissions at frequencies outside their intended transmission frequency band.

Conducted Immunity (also called Susceptibility) is a measure of the ability of electronic products to tolerate the influence of conducted electrical energy from other electronic products and electromagnetic phenomena.

Radiated Immunity (also called Susceptibility) is a measure of the ability of electronic products to tolerate the influence of radiated electrical energy from other electronic products and electromagnetic phenomena.

Simulates disturbances created by radio transmitters operating below 80 MHz (such as AM broadcast transmitters) that would typically be coupled onto a products interface cables.

Test Method

The test signal, amplitude modulated by a 1 kHz sine wave, is injected onto the AC or DC wires via a Coupling, Decoupling Network (CDN) while the frequency is varied. Unshielded cables can be tested using either a CDN, coupling clamp or current injection probe. Shielded cables are tested using direct injection, the signal is coupled through a 100-Ohm resistor onto the shield of the cable under test. The injection level is pre-calibrated using the appropriate calibration jig and is equivalent to the open circuit voltage at the output from the amplifier for an unmodulated signal.

The test level for the residential, commercial and light industrial generic standard is 3 Volts; for heavy industrial equipment the test level is 10 Volts.

We have a Frankonia SAC3Plus EMC chamber that we use for commercial testing. We have some height limitations in our laboratory and its dome shaped design fits very conveniently. We are happy with the performance of the chamber and their absorber design is great. No carbon dust and falling of foam absorbers. Previously we had carbon foam-based absorbers and we literally had to wear a safety hat before entering the chamber.
