September 25, 2008[TechView: Test] PXI Modules Provide Higher Frequencies, Speed, And Flexibility
At last month’s NIWeek conference in Austin, Texas, National Instruments introduced several RF products that are sure to be a hit with some engineers because of their higher frequency range, faster speeds, and lower costs. With RF testing becoming a larger part of the design and production testing of wireless technologies, these devices could yield faster time-to-market while decreasing test costs. NI also rolled out a line of Wi-FI testers...

September 11, 2008[Technology Report] The iNEMI Boundary-Scan Adoption Project
The International Electronics Manufacturing Initiative (iNEMI) is a virtual consortium of about 70 electronics manufacturers, suppliers, associations, government agencies, and universities. Its mission is to identify and close technology gaps, which includes the development and integration of the electronics industry supply infrastructure. Accelerated deployment of technology is shaped and led by iNEMI members, benefitting the global electronics industry. The...
September 11, 2008[Technology Report] The Embedded Plan For JTAG Boundary Scan
In 1990, the IEEE ratified the 1149.1 standard known as boundary scan. Developed by the Joint Task Action Group (JTAG), it was created to help solve the overwhelming testing problems caused by ever-increasing larger-scale ICs and densely packed multilayer printed-circuit boards (PCBs). The old “bed of nails” method of testing PCBs no longer worked as well, and the inaccessible circuits and even pins on ICs made testing difficult if not impossible. With boundary scan, IC and...
September 11, 2008[TechView: Communications] SERDES Chip Improves Signal Integrity, Provides For Real-Time Waveform Viewing
The VSC3441 high-speed serializer/deserializer (SERDES) from Vitesse Semiconductor incorporates clock and data recovery (CDR) circuits and advanced equalization to compensate for various impairments and losses encountered in copper cables and backplane traces and connectors. It also includes Vitesse’s VScope waveform viewing technology, making it possible to see the received signal as it really exists. The company crafted the chip in response to the need for higher-speed...
September 11, 2008[TechView: Communications] First Dual-Port 10GBaseT-Over-Copper Chip Slashes 10-Gbit/s Ethernet Gear
Many companies have been working for years to create the definitive 10-Gbit/s Ethernet physical layer (PHY) for copper cable. With the cost of optical 10 Gigabit Ethernet (10GE) ports lingering at about the $3000 level, copper ports still look attractive at $500/port with existing chips. Now, Teranetics is changing all that with its TNTN2022 10GE copper PHY chip. Offering two ports, it further reduces that per channel cost. 10GE copper PHY chips typically allow standard...
September 11, 2008[TechView: Communications] Fibre Channel Over Ethernet Adapters Simplify Infrastructure And Save Money
The 8000 series converged network adapters (CNAs) from QLogic Corporation aren’t just new network interface cards (NICs) or host bus adapters (HBAs). Instead, they’re the first CNAs to allow the Fibre Channel (FC) storage-area network (SAN) protocol to run directly on an Ethernet local-area network (LAN). SANs have grown in importance over the years as organizations now have tons more data to store. Most of those original networks employed FC, which uses high-speed fiber...

[Web Exclusive] CTIA Comes To The City By The Bay
The cellular industry is so hot right now, CTIA can’t contain all of its advances in just one show. This week, the Wireless Association presents its second event of the year at the Moscone Center in San Francisco. With 10,000 attendees expected, this follow-up to April’s Las Vegas show and February’s Mobile World Congress in Barcelona will focus on the IT and entertainment sides of the business.
August 28, 2008[TechView: Communications] IC Power Amp Targets Mobile WiMAX Apps
The mobile version of the WiMAX broadband wireless technology is beginning to roll out as laptop manufacturers add it to their PCs and as other companies make wireless access points for the home and office. Now, all of these designers have access to a WiMAX power amplifier (PA) thanks to SiGe Semiconductor. The SE7262L is a 2.5-GHz PA for batterypowered devices. It delivers 28.5 dBm of output power (708 mW) with an efficiency of 20%—not bad...
August 28, 2008[TechView: Wireless] ZigBee Wireless Module Sports 32-Bit ARM Processor
Lots of companies make IEEE 802.15.4 and ZigBee wireless modules, but only California Eastern Laboratories (CEL) offers one with an internal 32-bit ARM processor. The FreeStar Pro is a complete radio module that’s ready to go as a node in wireless network (see the figure). Based on Freescale Semiconductor’s MC13224V Platform-in-Package (PiP), the FreeStar Pro features the ARM 32-bit ...

[Web Exclusive] NIWeek Wrap Up
One of the best conferences I go to each year is NIWeek. Another has come and gone, but like always I got a glimpse at some solid technology from the mega-company. National Instruments has been sponsoring their own conference here in Austin, TX for several years now, and it has become a solid industry event. Why? Simply because NI’s products like LabVIEW software, data acquisition hardware, and virtual instruments have become so widely used.

[Web Exclusive] Is It Worth Waiting For The Next Generation iPhone?
The media is simply overflowing with articles on Apple’s iPhone 2.0 which came out last month. (June 9). I have already had the feeling that I was the only writer/editor/blogger/pundit who had NOT written about this device. So, here is my two cents worth. But to liven this up, I will tell you what I think will be the new and better features of the third version of the iPhone, not the newest one, but the (hypothetical) one just beyond.
August 14, 2008[Design FAQs] Automated Test Summit 2008
What is the Automated Test Summit? The Automated Test Summit is an annual virtual industry event for test and design engineers hosted by National Instruments. It includes a virtual trade show floor with exhibits, interactive Q&A, live keynotes, and several live technical tracks. You can experience all of these events just as you would if you were attending the conference yourself, but from the convenience of your desk...
August 14, 2008[Leapfrog: First Look] Big, Black, And Bold Oscilloscope Breaks Performance Barriers
The WavePro 7 Zi series from LeCroy revolutionizes oscilloscope design and functionality (Fig. 1). While the 15.3-in. WXGA LCD touchscreen can display all sorts of useful data at the same time, the real breakthrough is what’s inside, as its hardware and software make it one of the best scopes on the market. The series includes five basic models with maximum bandwidths of 1.5, 2.5, 3.5, 4, and 6...
August 14, 2008[TechView: Test] Updated Signal-Generation Software Uses Click-And-Drag GUI
Keithley Instruments has launched the 2.0 version of its SignalMeister Waveform Creation Software. Introduced last year, the original version of the software tool lets engineers create highly complex signals needed to test modern RF and wireless products.

August 14, 2008[Engineering Feature] Good Times For Ham Radio
I recently spoke with David Sumner (K1ZZ), the CEO of the Amateur Radio Relay League (ARRL), at the Dayton Hamvention, the big ham conference held every year in Dayton, Ohio. If you’re a ham, you know about the ARRL, which supports and promotes amateur radio. The organization is the ham’s interface with the Federal Communications Commission (FCC), and it lobbies for spectrum and other rights and benefits. It publishes the monthly ...
August 14, 2008[Engineering Feature] SDR Transforms Amateur Radio
Like almost everything else in electronics, radios are becoming processors with software that communicate via a small amount of RF I/O circuitry. Surely, then, the rise of software-defined radio (SDR) should come as no surprise. Digital signal processing (DSP) lies at the heart of SDR. Add to that the arrival of faster analog-to-digital and digital-to-analog converters (ADCs and DACs) and processors, and SDR becomes more viable for a wider range of...
August 14, 2008[Engineering Essentials] Welcome To Antennas 101
Antennas are much more than simple devices connected to every radio. They’re the transducers that convert the voltage from a transmitter into a radio signal. And they pick radio signals out of the air and convert them into a voltage for recovery in a receiver. Typically taken for granted and left for the last minute in a design, antennas are nonetheless critical for establishing and maintaining a reliable radio connection. They may look complex and enigmatic...
