Complex interconnected systems are increasingly becoming part of everyday life in both military and civilian environments. In the military domain, air-dominance system-of-systems concepts, such as those being developed under DARPA’s SoSITE effort, envision manned and unmanned aircraft linked by networks that seamlessly share data and resources in real time.
On Nov. 9, 2015, NASA’s Solar and Terrestrial Relations Observatory Ahead, or STEREO-A, once again began transmitting data at its full rate. For the previous year, STEREO-A was transmitting only a weak signal—or occasionally none at all—due to its position almost directly behind the sun.
University of Washington engineers have developed a novel technology that uses a Wi-Fi router — a source of ubiquitous but untapped energy in indoor environments — to power devices.
The development of high throughput satellites operating over Ku and Ka-band frequencies has increased the need for upgrading ground station inter-facility links (IFLs). RF transmissions are traditionally handled by copper coaxial cables, but they are no longer suitable due to their excessive size and restricted bandwidth. ETL Systems offers a new series of RF over fibre IFLs designed to deliver high quality RF signals across long distances with minimal loss.
Berkeley Nucleonics has recently enhanced the 7000 series of fully automated signal source analyzers, and has extended their measurement capabilities to 26 GHz. Not only do these devices measure absolute phase noise on a large variety CW sources, they also perform residual and absolute phase noise characterization of CW and pulsed signals, transient analysis, and VCO characterization. This application note discusses the features and benefits of two 7000 series models available for automated phase noise measurements.
Every day, networks face coverage issues at busy locations such as airports, shopping malls, and sporting/concert venues. This type of network density, coupled with high user demand, is the leading contributor to small cell growth.
Measuring RF power in a field environment can be a simple task which can be accomplished accurately and inexpensively. It can also involve a great deal of care and proper training to ensure equipment is accurately measured. Either way accurate field power measurements will ensure transmitting equipment is operating properly...
Technology advancements in the electronic industry yield new trends in RF communications that drive new product functionality. The use of electromagnetic (EM) simulation design tools, like FEKO, are extremely important in new advancements in the next generation of mobile phones, cameras, laptops, and other Internet of Things (IoT) devices. Incorporating EM simulation throughout the design cycle helps to explore, optimize, and innovate these new design challenges. This white paper discusses Altair’s EM solver, FEKO, and how it strives to provide solutions for design innovation in future technologies.
EMIT (electromagnetic interference toolkit) is a type of simulation software used to predict EMI (electromagnetic interference) in complex RF environments containing multiple transmitters and receivers, and to predict in-band and out-of-band interference effects for all Tx/Rx (transmitter/receiver) pairs in the scene.
Ensuring that all new biomedical devices meet regulatory and certification requirements is a necessity. Remcom's tools can greatly speed the design and certification process by allowing realistic simulations of the device performance before the costly prototyping stage. Analysis options available are for device performance such as tuning and bio-interaction including SAR. Realistic, poseable human body models are available in addition to CAD-based phantom models.
Remcom specializes in a variety of Bio/EM analysis areas including:
This 8-minute XFdtd getting started video details the triangle geometry construction of a bow tie antenna in Remcom’s FDTD 3D EM simulator, including the component placement of a voltage source driving the antenna. This video for new users also offers XFdtd orientation including accessing the User’s Guide and the XF project assistant work-flow checklist.
Remcom's XFdtd 3D EM simulator integrates with Optenni Lab for antenna matching circuit optimization. This brief video shows the highlights of the workflow and integration using a GPS and Bluetooth mobile device antenna.
This video gives a demonstration of Full Wave Antenna Matching Circuit Optimization using XFdtd's Circuit Element Optimizer (CEO). The antenna matching circuit design flow is discussed, including CEO's analysis of a given PCB layout. Predicted S-parameters and optimal component value results for two different frequency bands are also shown.
This video discusses how using Anritsu's MT1000A Network Master field transport tester can rival the BBU while performing quality testing.
Anritsu’s Network Master family of field-portable optical transport testers are designed to test service interfaces such as Ethernet, SONET/SDH, Fibre Channel and DSn, and emerging MPLS-TP, PBB-TE and ITU-T G.709 OTN. The independent two-port or four-port operation provides exceptional flexibility when testing network and transport equipment operating from 1.5 Gbps to >100 Gbps. This video provides a walkthrough of these instruments’ operation, and features the easy-to-use GUI, its test flow structure, and results reporting structure.
