Symmetricom	Common-View LORAN-C as a Backup to GPS for Precise Time Recovery The LORAN-C network is being recapitalized to serve as a backup to GPS for navigation and timing. This paper begins with a short overview of the LORAN-C recapitalization project with an emphasis on timing enhancements at the transmitting stations. A description of the commonview LORAN-C test network follows. Data collected in Boulder will be corrected via commonview using a near field station and ...

SecureWorks, Inc.	University Security Assessment This report contains the analysis of network traffic for University XYZ from March 25th through March 27th 2004. Log files were obtained from the University in order to identify threats to the security and performance of the network. Included in the set of logs to be analyzed were signature alert logs, port scanning logs, and out of specification (OOS) logs. Signature alert logs identify traffic ...

Business Industrial Network	The True Cost of Downtime Article The key to realizing greater savings from more informed management decisions is to predetermine the "True" cost of downtime for each profit center category. TDC is a methodology of analyzing all cost factors associated with downtime, and using this information for cost justification and day to day management decisions. Most likely, this data is already being collected in your facility, and need ...

Business Industrial Network	What is the True Downtime Cost (TDC)? The key to realizing greater savings from more informed management decisions is to predetermine the "True" cost of downtime for each profit center category. TDC is a methodology of analyzing all cost factors associated with downtime, and using this information for cost justification and day to day management decisions. Most likely, this data is already being collected in your facility, and need ...

CommScope	A Comparison of Total Costs of Ownership of 10 Gigabit Network Deployments in ... Technological advances, such as virtualization and multicore servers, open the way to a new generation of more efficient, higher performance data centers. The new developments can bring important benefits, but they also challenge organizations to make critical infrastructure decisions that will impact the future of their IT systems and ability to stay competitive. Among the most important of ...

Berkeley Varitronics Systems	Spread Spectrum Series Part 1 The application of telecommunications is often about ‘bandwidth conservation’. The technology of Spread Spectrum is exactly the opposite philosophy. Spread spectrum employs a novel form of modulation in which the RF bandwidth of the signal is much larger than that needed for traditional modulation schemes and the bandwidth is independent of the modulation content. Historically spread spectrum ...

Berkeley Varitronics Systems	Test Stimulus for Power amplifiers used in Cellular and PCS systems [CDMA] The CDMA system place new demands on component manufacturers, test equipment, and measurement techniques. Requirements for suppression of Adjacent Channel Power (ACP) have become more stringent than those required by the older analog systems. GSM systems, IS-54 or IS-136, use constant modulation envelope formats, and the digital TDMA and CDMA standards in North America use quadrature phase-shift ...

Symmetricom	Packet Network Readiness: Testing and Verifying IEEE 1588-2008 Packet ... Learn more about the importance of efficiently and accurately testing, measuring and analyzing PTP data to assure IEEE 1588 network readiness. This paper focuses on emerging new solutions for measuring packet synchronization and the requirements needed to ensure a consistent, predictable, measurable level of PTP network quality.

Berkeley Varitronics Systems	Measuring Digitally Modulated RF Signals Digitally modulated radio-frequency (RF) signals manifest unique characteristics at personal communications (PCS) frequencies when they are reflected. Reflections add out-of-phase data symbols that cause bit errors. Paradoxically, simple signal-strength measurements at PCS frequencies (using signals with a narrow bandwidth, such as a continuous wave [CW]) can be deceptive because, although the ...

RTTS	Massaging Test Data in Excel Using Macros and VBA Utilizing IBM Rational ... The quantity of data produced from an application-based performance test can be monumental when faced with the task of analyzing it. This whitepaper will explain how to use Visual Basic for Applications (VBA) and the macro functionality in Microsoft Excel to manipulate export data in order to save time in preparing performance data charts.
