This consolidated version consists of the first edition … [Read more...]

Test and Measurement Requirements for Single-Mode Fiber, Plug-Style Fixed Attenuator Devices

 

From the International Electrotechnical Commission webstore: “IEC 61753-051-3: 2013 contains the minimum initial test and measurement requirements and severities [that] a fiber optic attenuator [needs to] satisfy in order to be categorized as meeting the requirements of single-mode fiber, plug-style fixed attenuator devices used in uncontrolled environments. Optical … [Read more...]

Power-Dependent Surface Resistance of Superconductors at Microwave Frequencies

 

From the “International Electrotechnical Commission” webstore: “IEC 61788-16:2013 [describes] the standard measurement method of power-dependent surface resistance of superconductors at microwave frequencies by the sapphire resonator method. The measuring item is the power dependence of Rs at the resonant frequency. This method is applicable for a frequency in the range of 10 … [Read more...]

Signal Integrity Tests Up to 1,000 MHz on IEC 60603-7 and IEC 61076-3 Series Connectors

 

From the International Electrotechnical Commission webstore: "IEC 60512-28-100:2013 specifies the test methods for transmission performance for IEC 60603-7 and IEC 61076-3 series connectors up to 1,000 MHz. It is also suitable for testing lower frequency connectors; however, the test methodology specified in the detailed specification for any given connector remains the … [Read more...]

Methods of Measurement and Limits for Radiated Disturbances from Plasma Display Panel TVs in the Frequency Range 150 kHz to 30 MHz

 

From the International Electrotechnical Commission Webstore: “IEC/PAS 62825:2013(E), which is a publicly available specification, applies to plasma display panel TVs which are intended for use in residential or commercial environments, which have a visible display area with a diagonal dimension of 1 m or greater, and which are within the scope of CISPR 13 or CISPR 32.” “This … [Read more...]

Measurement of Passive Intermodulation in Antennas

 

From the International Electrotechnical Commission Webstore: “IEC 62037-6:2013(E) defines test fixtures and procedures recommended for measuring levels of passive intermodulation generated by antennas typically used in wireless communication systems. The purpose is to define qualification and acceptance test methods for antennas for use in low intermodulation (low IM) … [Read more...]

可形成局域网连接并可用于充电的桌子

 

来自东京大学的研究人员在日本举行的日本高新技术博览会（Ceatec）电子展上展出了一种桌子，这种桌子能够为置于其上面的装置提供无线充电并在装置之间形成一个局域网。这一概念源自于支持无线专网的想法，这种网络比当前的Wi-Fi网络更安全、更为局域化，同时也不需要网线。 这种桌子由小网面板组成的薄板制成，这种小网面板在两个维度内含有电磁波，并携带一个较小的电流。东京大学的一名博士生Akihito … [Read more...]

Protective Equipment for Series Capacitor Banks

 

From the International Electrotechnical Commission webstore: "IEC 60143-2:2012 covers protective equipment for series capacitor banks with a size larger than 10 Mvar per phase. Protective equipment is defined as the main circuit apparatus and ancillary equipment, which are part of a series capacitor installation, but which are external to the capacitor part itself. The … [Read more...]
