Analog/SDI to SDI/Optical Converter with TBC/Frame Sync User Guide
Analog/SDI to SDI/Optical Converter with TBC/Frame Sync User Guide ENSEMBLE DESIGNS Revision 6.0 SW v1.0.8 This user guide provides detailed information for using the BrightEye™1 Analog/SDI to SDI/Optical Converter with Time Base Corrector and Frame Sync. The information in this user guide is organized into the following sections: • Product Overview • Functional Description • Applications • Rear Connections • Operation • Front Panel Controls and Indicators • Using The BrightEye Control Application • Warranty and Factory Service • Specifications • Glossary BrightEye-1 BrightEye 1 Analog/SDI to SDI/Optical Converter with TBC/FS PRODUCT OVERVIEW The BrightEye™ 1 Converter is a self-contained unit that can accept both analog and digital video inputs and output them as optical signals. Analog signals are converted to digital form and are then frame synchronized to a user-supplied video reference signal. When the digital input is selected, it too is synchronized to the reference input. Time Base Error Correction is provided, allowing the use of non-synchronous sources such as consumer VTRs and DVD players. An internal test signal generator will produce Color Bars and the pathological checkfield test signals. The processed signal is output as a serial digital component television signal in accordance with ITU-R 601 in both electrical and optical form. Front panel controls permit the user to monitor input and reference status, proper optical laser operation, select video inputs and TBC/Frame Sync function, and adjust video level. Control and monitoring can also be done using the BrightEye PC or BrightEye Mac application from a personal computer with USB support. -

Performance Analysis of MIMO Spatial Multiplexing Using Different Antenna Configurations and Modulation Technique in Rician Channel Hardeep Singh, Lavish Kansal
International Journal of Scientific & Engineering Research, Volume 5, Issue 6, June-2014 34 ISSN 2229-5518 Performance Analysis of MIMO Spatial Multiplexing using different Antenna Configurations and Modulation Technique in Rician Channel Hardeep Singh, Lavish Kansal Abstract— MIMO systems which employs multiple antennas at the transmitter as well as at the receiver side is the key technique to be employed in next generation wireless communication systems. MIMO systems provide various benefits such as Spatial Diversity, Spatial Multiplexing to improve the system performance. In this paper the MIMO SM system is analysed for different antenna configurations (2×2, 3×3, 4×4) in Rician channel. The performance of the MIMO SM system is investigated for higher order modulation schemes (M-PSK, M-QAM) and Zero Forcing equalizer is employed at the receiving side. The simulation results points that if antenna configurations are shifted from 2×2 to 3×3 configuration, an improvement of 0 to 2.9 db in SNR is being noted and an improvement of 0 to 2.9 db is visualized if antenna configurations are changed from 3×3 to 4×4 configuration.

Importance of Microwave Antenna in Communication System
ISSN (Print) : 2320 – 3765 ISSN (Online): 2278 – 8875 International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering (A High Impact Factor, Monthly, Peer Reviewed Journal) Website: www.ijareeie.com Vol. 7, Issue 2, February 2018 Importance of Microwave Antenna in Communication System Shailesh Patwa1, Shubham Yadav2, Mohammad Saqib3 UG Student [BE], Dept. of ECE, Medicaps Institute of Technology and Management College, Indore, Madhya Pradesh, India1 UG Student [BE], Dept. of ECE, Medicaps Institute of Technology and Management College, Indore, Madhya Pradesh, India2 UG Student [BE], Dept. of ECE, Medicaps Institute of Technology and Management College, Indore, Madhya Pradesh, India3 ABSTRACT: This paper provide various types of information about microwave antenna in communication system. Antenna plays a crucial role in this communication system, which is used to transmit and receive the data. The classification of the antenna is based on the specifications like frequency, polarization, radiation, etc. In this we will observe some important point about microwave antenna in communication network, relay stations, transmission system, interconnection cable and inter-operations performing as an integrated whole. KEYWORDS: Microwave Antenna, Types of Antenna, Properties of Antenna, Applications of Antenna. I. INTRODUCTION The main purpose of this research to help people know many things about microwave antenna use in communication system. Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna. This allows nearby microwave equipment to use the same frequencies without interfering with each other, as lower frequency radio waves do. -
Inexpensive Microwave Antenna Demonstrations Based on the IEEE Presentation by John Kraus – Jon Wallace
Inexpensive Microwave Antenna Demonstrations Based on the IEEE Presentation by John Kraus – Jon Wallace Abstract: After seeing a video of John Kraus giving a demonstration on radio antennas to the IEEE many years ago, the author was so inspired that he researched the concepts and sought to reproduce as much of the demonstration as he could. It is hoped that these demonstrations will educate and inspire others to explore as well. They cover topics which include: beam width, inverse square law, polarization, reflection, refraction, interference, absorption, gain, wave guides, diffraction, and more. The equipment used consists of a Gunn diode source with horn antenna and a WR-90 horn antenna with crystal detector, instrumentation amplifier, and voltage controlled oscillator (VCO) so that changes in intensity will be heard as pitch changes. Safety Although these microwave frequencies are not the ones used for cooking, they can still cause damage to eyes and sensitive areas of the body. When I started this project I searched for the most stringent safety recommendations I could find for a 10 mW transmitter at about 10 GHz. This recommendation was to keep a minimum distance of 60 cm. (2 ft.). I also designed an aluminum-screened mask that can be worn when presenting the demonstrations. It completely blocks all radiation from the transmitter. Close-up pictures and hints on making one are included at the end of this document. Stay safe! The Equipment The various demonstration devices will be described in each section and building tips are included at the end of the paper. The basic equipment consists of a transmitter (a Gunn diode device) with a larger horn and regulated 8V power supply powered by a 9V battery, a receiver with a small horn antenna, crystal detector, instrumentation amplifier, voltage controlled oscillator, and powerful speaker.
