| Abstract | In this paper, a new and low-cost design of site source with long-term stability is proposed. The site source is especially suitable for the daily site checking and the consistency confirming at different test sites. For these applications, the site source is highly required to be stable due to various test sites and long-term usage. Two crystal driven oscillators together with well-designed circuits, powered by AC, can generate fast and stable periodic trapezoidal waveforms, resulting in harmonic signals ranging from 150 kHz to 1 GHz. This indicates that the site source can be applied not only for the radiated-emission (RE) test from 30 MHz to 1 GHz but also for the conducted-emission (CE) test from 150 kHz to 30 MHz. For demonstration, the site-source prototype was created and measured. The measurement was performed inside a standard 10-m semi-anechoic chamber to show the attractive performance of frequency accuracy, outputpower stability and radiation symmetry of the newly developed site source. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
