Expanding GNSS Testing with Multiple Synchronized Signal Recorders

In order to greatly expand recording bandwidth, you can deploy multiple tightly synchronized recorders in the field. Averna studied the example of two RP-5300 recorders (2x50 MHz channels each) that were synchronously inter-connected to form a virtual recorder with total bandwidth of 200 MHz.

Eliminate Risk of Contention and Data Corruption in RS-485 Communications

The RS-485 communications standard was introduced in 1983 by the Electronic Industries Alliance (EIA) as a two-wire, half-duplex, multi-drop alternative to the point-to-point RS-232 interface. (Note: RS-485 can also be wired using 4-wires to enable full-duplex communication). RS-485 uses differential signaling to allow up to 32 devices to communicate peer-to-peer at distances up to 4000 feet. In most RS-485 configurations two signals, a positive and a negative, are run as a twisted pair. Since these signals are compared to one another rather than a ground reference like RS-232, RS-485 communication is less susceptible to external noise injected on the wiring and performs more reliably in industrial environments.

Recruit Or Retain Report

In our recent Perfect Fit Survey, Aerotek found that the majority of hiring managers are happy with their last hire and many remain optimistic about finding the right candidate. However, results published in the January 2013 issue of The Quarterly Journal of Economics showed the average time to fill a position rose to 23 days in December 2012 compared to a low of 15.4 days in July 2009. The rhetoric of a historic skills gap has painted a negative picture of job seekers, but is there more to the story?

Overcome Challenges of Your Highly Constrained PCB Designs

Layout constraints are an essential part of a PCB design. As the technology in modern electronic devices has become more complex (e.g. increasing speed, decreasing rise time and supply voltage values), signal integrity issues have become a primary concern. For many designs, this means a large percentage of nets require PCB layout constraints to meet signal integrity requirements. This brings two major challenges: creating a proper set of layout constraints for your design and applying those constraints during the PCB layout design process. This paper shows how to address the challenges of highly constrained designs.

Removing the Gap Between ECAD and MCAD Design

For ECAD and MCAD to collaborate in “real-time” a direct method of communication that facilitates a shared flow of data back and forth between design teams is required. This flow must support “what-if” scenarios of design baselines and change proposals along with the ability to counter-propose changes. Once design agreements are made, the flow must also dynamically update the design databases. This unique ECAD-MCAD (EDMD) collaborative environment has not been available until now. This desktop PCB design provides a real-time integrated ECAD-MCAD collaboration environment that enables Electrical and Mechanical design teams to work together throughout the entire design process.

Developing Smart and Affordable Intelligence, Surveillance and Reconnaissance Technologies: Five Trends to Watch

The demand for intelligence, surveillance and reconnaissance (ISR) technology and infrastructure is growing significantly. For example, in the 10 years from 2002 to 2011, U.S. Defense spending on ISR grew by a factor of six, compared with relatively flat defense spending overall [House Permanent Select Committee on Intelligence, 2012]. Similar patterns of spending can be seen around the globe. Simulation-based engineering has long played a role in advancing ISR technology development — from unmanned systems to antennas to systems and embedded software. The value proposition has long been proven.
