Maybe it was because of the Computer Technology Solutions Show, but many companies are displaying their fall wares in splendid fashion. Because of this, it was difficult to choose one product this time. Steve Shoaf from IBM says that markets are changing. Companies don't address one market any more, but are targeting the individual, so they end up targeting 50,000 markets at once. This requires that businesses compete through innovation. "It is a digital economy and companies need tools to help them address that," Shoaf says. The products in this issue specifically meet that need, such as Unigraphics Version 16, my Pick of the Issue, as well as Cimatron and Simul8. IBM and Enovia also address the innovation engine of the production process with the ENOVIA Portfolio, an integrated solution containing ENOVIAvpm, ENOVIApm, CATweb, and ENOVIA-DMU Navigator. The VPM segment allows engineers to design and optimize a product and its associated processes and resources during development. The PM segment is a full-function product data management program. CATweb enables manufacturing teams to share product information with the non-engineering community via the Internet or Intranet. And lastly, DMU Navigator is for collaborative and 3D visualization, navigation, review and simulation of all sizes of digital mock-ups.

Design News editors follow industry trends in many ways. Besides making plant visits and attending trade shows, we host many OEM suppliers who come to our offices to highlight and demonstrate their latest products, services, and applications. In the area of test and measurement equipment, and particularly oscilloscope technology, one only has to have read our last few issues to see that the industry's major players have been parading through our cubicles at a nearly breakneck pace--almost all of them have simultaneously introduced new, higher speed and greater memory models, as well as features such as voice control.
Under shorter design cycles, design test engineers must validate devices with ever-tighter circuit densities and higher bandwidth operations. But to paraphrase Lord Kelvin, "If we can't measure it, we can't know it." Fortunately, vendors are making it easier for designers to determine how well their latest demanding electronic designs and concepts perform, either to validate the components or adjust characteristics to meet requirements.
The very microchip- and processor-equipped devices (plus software) such test gear is measuring, are the sources, in turn, of equipment improvements. Not only is the basic electronic performance being enhanced, but also the physical versatility of the test equipment itself. Lower-power flat panel displays are cutting the bulk, weight, and power consumption of oscilloscopes. Thus, more powerful machines are becoming more portable, and the economies of scale are increasing performance per dollar spent.
If you're a design test engineer and haven't looked up from your oscilloscope in the last few weeks, take a glance around to see what manufacturers are now offering you to get your projects done "better, faster, and cheaper."

Handheld, high-speed scopes
First out of the gate this month in the oscilloscope sweepstakes is a handheld unit for designers and others doing field or remote site testing, featuring the data storage and analysis capabilities of many desktop units. The Fluke ScopeMeter(R) 190 Series battery-powered oscilloscopes offer up to 200 MHz bandwidth and 2.5 GS amples/sec real-time sampling using separate digitizers on both isolated inputs. The series features a memory of 27,500 data points per input for long duration, high-resolution recording. A Connect-and-ViewTM function recognizes signal patterns to set up correct, automatic triggering for displaying a signal of interest, all without the user needing to reconfigure the instrument. And any signal changes are recognized and settings adjusted for a stable display. In normal mode, the last hundred screens are "memorized," so that using a replay button allows scrolling back in time to catch any anomaly as fast as 50 nsec. A "baby-sit" mode can capture up to 100 predefined glitches or signal anomalies. A NiMH battery provides four hours of operation.

Lightpipes direct light from PCB-mounted LEDs to the front of the modjack to indicate system activity. The customer-supplied surface-mount LEDs, in combination with the lightpipes, reduce EMI/RFI noise by 50% compared to a modular jack with integral LEDs, says the company. Replacement cost is also reduced because there are no LEDs on the jacks to fail. The modjacks have a plug latch on the top for easy demating and they are available in shielded and unshielded versions for both RJ11 and RJ45 styles.
