Oscilloscopes

Agilent Technologies Inc. (Santa Clara, CA) expanded its mixed-signal and digital-storage oscilloscope portfolio with 10 new models that comprise its InfiniiVision 7000 Series. The InfiniiVision 7000 Series offers bandwidths up to 1 GHz and delivers a deep memory waveform update rate of up to 100,000 waveforms per second. Each model is equipped with a 12.1-inch XGA LCD display and comes in a compact package that's just 7 inches deep and weighs 14 pounds. The increased display size helps users who need to display up to 20 channels simultaneously with serial protocol. The update rate is 5,000 times faster than any other available scope, and allows the user to view critical signal detail that other scopes might miss with their longer dead times.

Data-Based Paradigm for Rapid Development of Advanced Avionics Displays

The database concepts, tools, and runtime software described in this article provide a methodology for creating advanced avionics human-machine interfaces (HMIs), such as those found in modern flat-panel display systems. The key innovation described is the ability to treat the avionics displays as databases rather than as compiled and linked software. This new technology facilitates the goals of open architecture for avionics, a key avionics industry trend.

FPGA-Based Communication Channel for Digital Signal Processor Chips

A method for networking, and a network of, digital signal processors (DSP) via at least one field-programmable gate array (FPGA) enables the simultaneous broadcast of data from a DSP to a number of DSPs. The apparatus comprises a host DSP, at least one FPGA in communication with the host DSP for receiving a digital signal from the host DSP, and at least one non-host DSP in communication with at least one FPGA for receiving the digital signal.

Applying Reconfigurable Computing to Acoustic Sensors Using FPGAs

A novel microsensor processing architecture allows a field-programmable gate array (FPGA) to act as a reprogrammable preprocessor or coprocessor to a general-purpose processor (GPP). The FPGA does most of the computationally complex pieces of the algorithm, while the GPP is lightly loaded, performing control, communications, and housekeeping tasks (Figure 1). The flexible architecture supports a wide range of low-power applications, while still being able to leverage emerging commercial technology.

Delta-Sigma UHF Digital Waveform Generator

A prototype Digital Waveform Generator (DWG) in the ultra-high-frequency (UHF) range uses Delta-Sigma (Δ−Σ) modulation techniques, which permit arbitrary and accurate waveform generation. The DWG meets the demanding and diverse waveform requirements of future radar applications, including linear-FM (LFM) and continuous wave (CW) signals. This DWG also allows for the generation of waveforms at other frequencies by up-conversion or down-conversion.

Network-Enabled Resource Devices

Network Enabled Resource Devices (NERDs) combine the most common electronic components used in robotic applications into a standard electronics box with "plug-n-play" capabilities. Risk reduction efforts, systems testing and integration, and modifying the functionality of evolving systems becomes greatly simplified by standardizing core hardware and software components; in many cases, minimal software modifications are required to adapt an existing NERD for an emergent application.

Cleaning and Protecting Large Mirrors Using a Polymer Solution

Cleaning and protecting optics is a challenge — contamination must be removed without damaging the surface. Preventing recontamination for extended periods of time after cleaning was unattainable prior to use of polymer strip coat films. The SLRSC Western Range Depot Optics Group, WRDOG, at Vandenberg Air Force Base, is a pioneer in the cleaning and protection of precision glass optics, lenses, and large mirrors using polymer solution technology.

Software-Defined Radios for Urban and Indoor Navigation

Software-defined radios (SDRs) are being developed to provide positioning and communication (POSCOMM) services inside buildings and tunnels, under tree canopies, and in other environments in which local radio- communication systems are accessible but Global Positioning System (GPS) signals are not present or are degraded. These SDRs could be especially helpful for teams of first responders (e.g., firefighters), and military personnel operating in urban settings. These SDRs are capable of navigating by use of GPS signals and can switch over to time-of-arrival (TOA) pseudolite navigation when GPS signals become unavailable, provided that signals from suitably placed TOA pseudolite transmitter nodes are available.
