This study gives the evaluation of the high voltage dc corona. For this purpose, electromagnetic characteristics of the dc corona discharge are observed. Both the positive and the negative corona for dc voltages are taken into account. The main concern is the electromagnetic interference caused by the corona. The level of noise is evaluated by the tests performed in semi-anechoic chamber, with different electrodes

Amplitude probability distribution (APD) has been proposed within CISPR as a measure of the emitted electromagnetic energy from electrical equipment. APD describes the envelope statistics of a disturbance from the IF filter of the measurement receiver and is in many ways a suitable model of nonGaussian noise, when determining its impact on a digital communication system. In an earlier paper, the connection between the APD of a disturbance and its effect on a digital receiver was presented. However, to derive a maximum allowed APD out of a maximum allowed bit error probability is a non-trivial problem. Unfortunately, this is exactly the issue when emission requirements should be related to the APD. This paper presents a possible way to put requirements on the APD in order to protect digital communication systems. By letting a measured APD of a disturbance lay below the requirements, the impact on a variety of receivers are guaranteed to not exceed the maximum bit error probability

In the paper an approach to contribution of the oscilloscope in uncertainty estimation of the rise time by measurement of the ESD discharge current is performed. Correlation between input signal and the displayed voltage at the oscilloscope called here transmittance is measured and approximated with the second order low pass filter along with the Gauss filters. Voltage at the oscilloscope input is calculated as the product of the analytically expressed current and measured input impedance of the oscilloscope. Moreover measurement uncertainty of input impedance and oscilloscope transmittance are built in the uncertainty estimation. The approach is compared with the two rules concerning conservative estimation of the rise time of oscilloscopes as stated in C. Mittermayer and A. Steiniger (for original article see IEEE Trans. on instrumentation and measurement Vol. 48, No. 6, p. 1103-7, December 1999). Presented calculations of the uncertainty of the rise time for pulses with different rise time shows advantages and better suitability of the novel method by measurement of the ESD discharge current
本文提出了一种通过测量ESD放电电流来确定示波器对上升时间不确定度的贡献的方法。输入信号与示波器上显示的电压之间的相关性在这里被称为透射率，用二阶低通滤波器和高斯滤波器测量和近似。示波器输入端的电压是用解析表示的电流和示波器的测量输入阻抗的乘积来计算的。在不确定度估计中引入了输入阻抗和示波器透射率的测量不确定度。该方法与C. Mittermayer和A. Steiniger所述的关于示波器上升时间保守估计的两条规则进行了比较(原文见IEEE翻译)。仪器与测量，Vol. 48, No. 6, p. 1103-7, 1999年12月)。对不同上升时间脉冲的上升时间不确定度进行了计算，通过测量ESD放电电流表明了该方法的优越性和较好的适用性

We analyze the wave propagation characteristic of the CISPR 25 radiated emission test setup with numerical simulations. Bad repeatability of the standardized ALSE validation procedure urged us to develop a new, more stable procedure. Our new validation procedure uses a small conical, dipole antenna instead of the test harness which improves the repeatability and avoids impedance problems of the artificial network and the noise source. Furthermore it allows precise measurements to investigate the influence of test bench dimensions and grounding. Results of these investigations are shown

A method of measuring the complex antenna factor (CAF) using the matrix pencil method is presented. The transmission coefficient measured between two antennas placed in an anechoic chamber is processed using the matrix pencil method to reduce the reflected wave component. As a result, the process using the complex antenna method is more effective than that using the gating in the time domain for reduction of ambient reflection in the measurement of the CAF

This paper discusses the development of aircraft EMC from its beginning finishing with a discussion of the challenges currently facing the various standardisation committees. Aircraft EMC requirements have undergone a process of continuous change driven by the ever increasing electromagnetic (EM) environment, both in terms of amplitude and frequency range, and the increasing use of electronics in the critical functions of aircraft systems

To protect equipment and personnel in high voltage test hall effectively, it is necessary to know the distributions of space electromagnetic field and frequency spectrum characteristics. A set of transient magnetic field waveform measurements and digital reconstruction method was used in discharge and withstand test of impulse voltage generator. Distributions of magnetic field and waveform characteristics have been measured. The results show that magnetic field of discharge test is larger than that of withstand test either in lightning impulse voltage test or in switching impulse voltage test. The magnetic field of many points have exceeded the level of computer misoperation and the rise time of waveform is also very short, so necessary protection and an EMC test to the equipment working in high voltage test hall are very necessary

In this work, electric field measurements are made in three categories. These are the near field measurements very close to the GSM phone for different phases (ringing, dialing, speaking) at the front, back, right and left sides of the phone, the electric field measurements at between 0-5 cm (1 cm intervals) away from the face and back of the GSM phone and the electric field measurements between 0-10 cm (1 cm intervals) away from the helix antenna which is fed by a 900MHz RF signal generator. These measurements were made by FP5000 isotropic probe that has frequency range between 10kHz-1GHz, dynamic range 1-300V/m. Fully charged mobile phone, which is under test, was fixed vertically on wooden platform and maximum electric field values were recorded. Only the position of probe was changed. During outgoing call phase, it's observed that the electric field at very close to mobile phone is much higher than limits specified by ICNIRP

Most of mobile radio networks that operate nowadays have been designed based on the classical cellular concept. However, during the last decade, an interest to find alternate design strategies has raised for several reasons. In general, the traffic density cannot be assumed constant throughout, making necessary the relocation of base stations inside the traffic hot spots. If traffic is characterized in a discrete manner, the optimal base stations location problem can be treated as a well-known problem in signal processing called vector quantization. We found that applying such a design strategy, better frequency assignments for a network can be accomplished

The paper deals with the contribution of few parameters governing the PLC emission phenomena. From experiments injecting high frequency current by means of a balun some interesting data will be selected. Especially it is shown that above a distance of 20 centimetres from the line its emission is mainly due to the common mode current merging from the balun. Measurements extended to indoor room configuration show that radiation is characterized by a specific frequency depending of the quarter wavelength resonance of the line under test. Some other results about the coupling effects bounded by this frequency will be presented. To conclude these experiments will be extended to indoor PLC powered with 220V 50 Hz in order to determine the effects provided by the loads connected on the line and to known change of coupling phenomena introduced by the building long tree shaped line
