Design & Implementation of Network Protocol Analyzer ab 35.9 EURO Network Security
The threats against the Bluetooth wireless industrial networks are caused by a logical design flaw, an implementation flaw or a fundamental weakness, so an attacker can pose a threat to damage the network. This work explores the threats against the Bluetooth industrial networks, when a built-in security mechanism is enabled or not. It puts an exclusive focus on attacker's capabilities equipped with protocol analyzer to get the required information for hop sequence synchronization to eavesdrop the Bluetooth communication, with capturing or without capturing the FHS packet, and also the analysis & development of various software defined radio applications using a MATLAB/Simulink and USRP2. This work also presents a complete SDR based prototype solution to get the master device address and its clock value, by intercepting and demodulating the FHS packet exchanged during the inquiry or the page procedure, furthermore without capturing the FHS packet just listing for a short time on a fixed RF frequency out of the 79 Bluetooth channels. The prototype system is build and interfaced with an USRP mother board and RFX2400 daughter board using the GNU radio framework.
Within this Project, the main goal is to find the approximate values of the parasitic elements for 0805 SMD resistors and capacitors as well as 0603 SMD resistors and capacitors when operated on higher frequencies. To achieve the required task, the substrate RT/duroid 5870 (Rogers Corporation) with a printed copper transmission line on it, was used. This transmission line was cut in the middle and the SMD components were fixed on that gap by soldering at both sides. This model was then placed on a solid copper box and attached to the Network Analyzer with the help of connectors. The measurements were taken within the frequency range of 50 MHz and 10 GHz and transferred from the Network Analyzer to the computer (attached to the Network Analyzer) with the help of the ADS (Advanced Design System) software. Finally, compatible circuit models (for resistors and capacitors) were created in ADS by considering all the parasitic elements and the recorded measurements (respective S-parameters) were matched and optimized by using the fitting technique as well as by the different features of ADS.
In this book, a systematic approach for the design, fabrication and testing of antennas using Ink Jet Printing Technology (IJPT) is presented. The antennas are fabricated using DMP-2800 Dimatix FujiFilm Material Printer and Sliver Nano Particles (SNP) ink. The 3D electromagnetic simulation softwares CST MWS and HFSS are used to design the antennas reported in this book . In addition to simulation, measurements of the antenna parameters have been performed using a vector network analyzer and UALR's anechoic chamber. An initial antenna design based on the traditional square patch geometry is involved as a benchmark to characterize the entire approach adopted to design any antenna geometry. The systematic approach for the manufacturing process includes the optimal number of printed layers, curing temperature and curing time, to achieve high electrical conductivity.
This book is concerned with the design, construction and testing of a 1.3GHz microstrip rectangular patch antenna. The patch antenna incorporated a feed-line on the PCB board. The first part of the design of the antenna involved the computation of the dimensions of the patch to achieve a fundamental frequency of 1.3GHz. The accuracy of the computed dimensions was confirmed on an Ansoft Designer simulation package by examining the return loss of the antenna at the resonant frequencies. The second part of the design of the antenna involved the computation of the performance of the antenna. A number of parameters were evaluated which included electric field, E and H planes, radiation pattern, radiation, conductance, directivity and efficiency. The use of approximate formulas, the MAPLE computer algebra package and the MATLAB package were used to evaluate the formulas for predicting the antenna parameters. Computations of the various performance parameters were confirmed on the Ansoft Designer simulator. The microstrip rectangular patch antenna was constructed in the laboratory and tested on a Network Analyzer. The responses showed good agreement with the Ansoft simulation results.

Protocol Analyzer monitors exactly what is happening on Network & observes what other users are doing. It is easy to use tool to capture the traffic on the Subnet & display real time statistics while capturing packets.Protocol analyzers should provide three main sources of information about your LAN in addition, various protocols including TCP/IP are used in conjunction with networks. In order to detect protocol misbehaviors and failures in networks, it is required to analyze these protocols and inspect interactions among them.
High Quality Content by WIKIPEDIA articles! X-parameters are a mathematical superset of S-parameters and are used for characterizing the amplitudes & relative phase of harmonics generated by nonlinear components under large input power levels. X-parameters represent a new category of nonlinear network parameters for high-frequency design and were developed and introduced by Agilent Technologies as functionality included in N5242 Nonlinear Vector Network Analyzer, and the W2200 Advanced Design System in 2008. (Nonlinear vector network analyzers are sometimes called large signal network analyzers.) X-parameters are applicable to both large-signal and small-signal conditions, for linear and nonlinear components. They are a mathematical superset of S-parameters meaning that, in the limit of a small signal, Agilent s X-parameters reduce to S-parameters.
This book provides state-of-the-art coverage for making measurements on RF and Microwave Components, both active and passive. A perfect reference for R&D and Test Engineers, with topics ranging from the best practices for basic measurements, to an in-depth analysis of errors, correction methods, and uncertainty analysis, this book provides everything you need to understand microwave measurements. With primary focus on active and passive measurements using a Vector Network Analyzer, these techniques and analysis are equally applicable to measurements made with Spectrum Analyzers or Noise Figure Analyzers. The early chapters provide a theoretical basis for measurements complete with extensive definitions and descriptions of component characteristics and measurement parameters. The latter chapters give detailed examples for cases of cable, connector and filter measurements; low noise, high-gain and high power amplifier measurements, a wide range of mixer and frequency converter measurements, and a full examination of fixturing, de-embedding, balanced measurements and calibration techniques. The chapter on time-domain theory and measurements is the most complete treatment on the subject yet presented, with details of the underlying mathematics and new material on time domain gating. As the inventor of many of the methods presented, and with 30 years as a development engineer on the most modern measurement platforms, the author presents unique insights into the understanding of modern measurement theory. Key Features: * Explains the interactions between the device-under-test (DUT) and the measuring equipment by demonstrating the best practices for ascertaining the true nature of the DUT, and optimizing the time to set up and measure * Offers a detailed explanation of algorithms and mathematics behind measurements and error correction * Provides numerous illustrations (e.g. block-diagrams for circuit connections and measurement setups) and practical examples on real-world devices, which can provide immediate benefit to the reader * Written by the principle developer and designer of many of the measurement methods described This book will be an invaluable guide for RF and microwave R&D and test engineers, satellite test engineers, radar engineers, power amplifier designers, LNA designers, and mixer designers. University researchers and graduate students in microwave design and test will also find this book of interest.
