National Instruments introduces Source Measure Unit (SMU) for PXI
The NI PXI-4130 Power SMU provides 4-quadrant operation on a 20V, 2A programmable channel. When combined with LabVIEW or LabVIEW SignalExpress software, this flexible module can be used to generate and measure precise voltage and current sweeps for curve tracing applications and device validation.
Squeeze 10-Bit Performance From An 8-Bit DAC Part 1: Additive Dithering
By Dave Van Ess, Application Engineer, MTS, Cypress Semiconductor
What’s the cost of an underused hardware resource? If you spec your microcontroller to have a 10-bit analog-to-digital converter (ADC) but only require 8 bits, you’ve paid for extra performance that just isn’t needed.
Electronic Design's Editor-in-Chief Joe Desposito traveled a long way to catch IEF. Catch up with him on his journey to Dubai, where IEF was held this year, and check out his impressions of the forum.
There was a ton of announcements at the Embedded Systems Conference last month. Check out the highlights, exclusive commentary, and footage from the show by Electronic Design's Editor-in-Chief Joe Desposito on our Web page, sponsored by Lantronix, Xilinx, and Altium.

Software Radio PMC Packs 256 DDC Channels
Raising the density bar, the Model 7151 software radio PMC combines four 200-MHz, 16-bit ADCs that feed a proprietary FPGA IP core with 256 channels of digital downconversion (DDC). With independent frequency tuning for each DDC channel, the PMC downconverts any signal within any of four digitized, 100-MHz input bands.
Static source code analysis tools can be an invaluable tool for software developers. Technology Editor Bill Wong talks with some of the major vendors in this space.
Learn how to automate your test system using solid state switches
This application note from Agilent provides a complete overview of FET, PIN diode, and hybrid solid-state switches. It discusses the features of each type of switch, which specifications to consider and why, and gives application examples.
The c-Link Systems Trak-Bot is a tabletop educational robotic vehicle used to explore and demonstrate autonomous vehicle motion. The robot is perfect for students and hobbyists to test motion programming or autonomous concepts that need to be demonstrated. The drive system was created to look and feel like its bigger brothers: bulldozers and military tanks. The tracks are of an Elastomer material that doesn't mark or mar surfaces while gaining a modicum of traction. The chassis is constructed of ABS plastic, which allows for customization and custom painting. Creation of programs for the —P robot can be handled through Cypress PSoC Express. The —C3 robot contains an Altera Cyclone-III EP3C5, a field-programmable gate array (FPGA) that can be configured with a 32-bit CPU (NIOS II). The —U robot contains a 48-pin dual-inline package (DIP) plug-in for add-on features and other vendor processors. The user’s imagination is the only real limitation to what the control cards can do. Optional add-ons increase the educational potential exponentially.
The ZigBee short-range wireless networking technology adds a complex stack to the IEEE 802.15.4 wireless standard, making it a bear to work with—especially for designers who aren’t so wirelessly inclined. But if you want to do mesh networking, it’s the way to go. Just be prepared for a steep learning curve and a compliance process that takes both time and money.
Fast Serial 16-Bit ADC Cuts Pin Count And PCB Space
Some new wireless and communications applications like basestations require 16-bit resolution as well as high sampling speed. Devices with high sampling rates are readily available, but some analog-to-digital converters (ADCs) require transferring all that data over a 16-bit data bus with a minimum of 16 lines, and, in some cases, 32 lines.
Report Sees Strong Growth For Organic Photovoltaics
The market for organic photovoltaic (PV) cells will generate nearly $1 billion in revenues by 2015, according to a report by NanoMarkets, an industry analyst firm based in Glen Allen, Va. The report notes that 2008 is the first year that organic PV products will be available commercially and that progress in the organic PV sector is attributable to the substantial venture capital and strategic investments that have been made in recent years.
The NanoBusiness Alliance reports that the House Science and Technology Committee has unanimously reported the National Nanotechnology Initiative (NNI) Amendments Act (H.R. 5940). The act will update and expand the National Nanotechnology Initiative.

Aftermarket Battery Packs - Revelations from Product Tear-Downs
Aftermarket battery packs are available for most portable devices. Hosted by Robin Sarah Tichy, Technical Marketing Manager with Micro Power and contributor to Electronic Design's Power Design column, this webcast will present the results of several product tear-downs on aftermarket battery packs and explain how substandard aftermarket packs can cut corners on cost, safety mechanisms, and battery performance. These teardowns expose electronic & mechanical design issues, as well as good manufacturing and regulatory violations. Then, this webcast will provide solutions for OEMs to manage and control their ecosystem of aftermarket battery pack suppliers. The webcast is applicable to OEMs of consumer and industrial electronic products susceptible to aftermarket batteries, such as medical, handheld radio, and data collection devices.
