Conducted Emissions

Knowledge of the conducted emissions in the frequency range 2–150 kHz contains some gaps related to the impact of the harmonics in the supply voltage on the nature of these emissions. It can be noticed that the conducted emissions from non-sinusoidal power supplies have not been studied sufficiently, and that the impact of this distortion may be greater than the generally known results of emission tests carried out under standardized test conditions. This paper is aimed at investigating experimental cases of the influence of supply voltage waveform distortion on non-intentional emission in the range 2–150 kHz and the efficiency of power line communication based on selected PRIME (PoweRline Intelligent Metering Evolution) power line communication (PLC) technology. A series of experimental laboratory studies were investigated, representing the operation of the investigated PLC system with different types of end-user equipment (LED—Light Emitting Diode, CFL—Compact Fluorescent Lamp, induction motor with frequency converter) working under a distorted supply voltage condition obtained by the programmable power supply for different scenarios of the admissible harmonics contribution in the range 0–2 kHz. The scenarios included limits defined in standards EN 50160 and IEC 61000-4-13. The researchers used spectral analysis with a notation to emission limits, compatibility levels, and mains signalling, as well as statistics of the PLC communication. The obtained results provide important conclusions, which may be applied both in the development of the design of the appliances in question and the higher frequency emission testing methods.

Test Process

Satellite navigation technologies are widely used around the world. Existing systems are constantly being upgraded, new satellites are being launched, satellite signals are being improved, military signals that are more resistant to interference are being gated in, ground-based navigation systems are being deployed, and the characteristics of GNSS user equipment are being improved. The effectiveness of GNSS user equipment is influenced by many different factors - from its internal circuit to the signal transmission medium where it is used. Testing of GNSS equipment consists in characterization of system performance and ensuring that manufacturer quality standards are met and expectations of the end user are satisfied. The solution of problems related to the testing of GNSS user equipment is the use of such equipment as simulators, GNSS signal recording and reproduction equipment, broad spectrum signal generation equipment, software for testing GNSS user equipment in laboratory conditions. The abovementioned equipment makes it possible to fully automate the test process by repeatedly performing user-defined scenarios. The use of signal generators for GNSS simulation has advantages over the use of a live GNSS signal. When using live signals the test conditions change constantly and unpredictably, therefore it is unlikely that two identical sequential tests will be performed under the same conditions. Retest is the most important requirement for the test process. The article deals with methods improvement and proposes the choice for rational equipment composition for GNSS user testing equipment.
