Network Analysis Software

OMICRON Lab (Houston, TX) has released new operation software for its Bode 100 portable network analyzer, giving users access to an extended frequency range. With the release of Bode Analyzer Suite V2.2, OMICRON Lab has managed to reduce the lower frequency border down to 1 Hz, giving the Bode 100 a range of 1 Hz – 40 MHz for Gain/Phase and impedance measurements. This extended frequency range makes the Bode 100 suitable not only for classical network analysis but also for the analysis of control circuits (e.g. DC/DC Converters), audio and ultrasound measurements, and the measurement of piezoelectric sensors and transducers. Other features of the new operation software include a straightforward and intuitive graphical user interface and OLE compatible automation interface, which facilitates integration of the Bode 100 into automated measurement setups for a variety of manufacturing or quality control applications.

Compact Embedded Computer

Mercury Computer Systems (Chelmsford, MA) has introduced the PowerBlock™ 50 system, a high-performance, ultra-compact embedded computer. The system’s modular architecture allows for flexible configurations of multiple processors, delivering well over 100 GFLOPS of processing power in a small, lightweight package. A fully configured PowerBlock 50 weighs less than 10 pounds and measures approximately 4" × 5" × 6". The system is available now as the PowerBlock 50 EDK (Engineering Development Kit), which is a complete software development platform. The EDK includes a PowerBlock 50 system, Linux BSP development environment, and a desktop heat rejection unit (HRU) to support the PowerBlock 50’s cooling requirements. The PowerBlock 50 EDK is customizable into configurations that include PowerQUICC™, Virtex™-4, and Intel processors, and SATA storage. Each configuration includes Gigabit Ethernet and RS-232 I/O interfaces.

Ethernet Protocol Analyzer

Absolute Analysis (Newbury Park, CA) has released a 10Gbps Ethernet protocol analyzer employing a SFP+ (Small Form-Factor Pluggable) interface and support for the 10GBase-LRM (Long Reach Multimode) standard. The 10Gbps SFP+ test solution provides developers with the capability to connect up to 16 ports in a single chassis, simultaneously utilizing both Ethernet and Fiber Channel. These ports are each synchronized to a common clock, allowing users to monitor multiple points in the network and aggregated links, and time correlate trace information for anomalies.

Simultaneous Ultra Fast Framing and Streak Imaging

The ability to record simultaneous framing images and streak images has long been a requirement in the research fields of detonation, electrical discharge, biomedical and many other applications. Early systems incorporating both framing and streak cameras used external beam splitting optics with light gathering limitations that required critical alignment of the external splitting optics. Later systems incorporated framing cameras and streak cameras, built into one mainframe, using available beam splitters. This allowed for simultaneous framing and streak, however, this type of beam splitter limited access to streak optics, and primarily limited the performance of the streak camera due to the smaller format streak tubes.

Tactile Feedback for Touch-input Devices

As products become more featurerich, manufacturers are looking at ways to improve the human-computer interface (HCI). Touchscreens, with intuitive operation and software flexibility, and screen-printed touch surfaces, with refined aesthetics and better sealing, have become extremely popular. But what these touch-input devices do not supply is tactile confirmation of (1) a button’s location and (2) pressing it. The loss of this tactile information can be detrimental to user engagement and understanding, productivity, completion of transactions, safety, and satisfaction. In some applications, the lack of tactile feedback has been enough of a problem to prevent the conversion from mechanical switches to digital controls. The solution is simple — add tactile feedback to secure the best features of touch-input devices.

Phase Matching of Diverse Modes in a WGM Resonator

Phase matching is necessary for exploitation of nonlinear optical phenomena.

Phase matching of diverse electromagnetic modes (specifically, coexisting optical and microwave modes) in a whispering-gallery-mode (WGM) resonator has been predicted theoretically and verified experimentally. Such phase matching is necessary for storage of microwave/terahertz and optical electromagnetic energy in the same resonator, as needed for exploitation of nonlinear optical phenomena.

Microwave-to-Optical Conversion in WGM Resonators

Three-wave mixing, resonance, and low loss would result in high efficiency.

Microwave-to-optical frequency converters based on whispering-gallery-mode (WGM) resonators have been proposed as mixers for the input ends of microwave receivers in which, downstream of the input ends, signals would be processed photonically. A frequency converter as proposed (see figure) would exploit the nonlinearity of the electromagnetic response of a WGM resonator made of LiNbO3 or another suitable ferroelectric material. Up-conversion would take place by three-wave mixing in the resonator.

Wide-Band Microwave Receivers Using Photonic Processing

One receiver would have the functionality of multiple traditional heterodyne microwave receivers.

In wide-band microwave receivers of a type now undergoing development, the incoming microwave signals are electronically preamplified, then frequency-up-converted to optical signals that are processed photonically before being detected. This approach differs from the traditional approach, in which incoming microwave signals are processed by purely electronic means. As used here, “wide-band microwave receivers” refers especially to receivers capable of reception at any frequency throughout the range from about 90 to about 300 GHz. The advantage expected to be gained by following the up-conversion-and-photonic-processing approach is the ability to overcome the limitations of currently available detectors and tunable local oscillators in the frequency range of interest.
