| Abstract | Measurements of electromagnetic interference in time-domain allow to reduce the scan time by several orders of magnitude, in comparison to automated scans performed by the tuned selective voltmeters, which are known as EMI receivers. Spectrum analyzer are used for fast sweeps to get an overview. Such analyzers can perform fast sweeps or scans over large bands. With the update of CISPR 16-1-1 Ed 3.1 the requirements for time-domain EMI measurement systems have been described. These time-domain EMI measurement systems are using the short-time fast Fourier transform to simulate a set of up to 4000 receivers simultaneously. A major requirement is the gapless aquisition during the dwell time. In this paper the requirements and solutions for time-domain measurements are discussed. A major requirement is the gapless processing of the input signal. This requirement is mandatory to detect over the observation time an isolated impulse. Further requirements are IF-filter bandwidths and indication in the various detector modes for different pulse repetition frequencies as well as the dynamic range. In this paper also the requirements regarding calibration are discussed. It is shown that time-domain measurement system can be used for the accurate measurement for a full compliance final measurement and also for ultra fast sweeps, replacing spectrum analyzers. In both cases the sweep and scantimes are reduced. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
