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

innovation engine of the production process with the ENOVIA Portfolio, an
integrated solution containing ENOVIAvpm, ENOVIApm, CATweb, and ENOVIA-DMU

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® 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.

The Programmable Field Controller for the WAGO-I/O-SYSTEM allows users to
store and execute programs locally and still communicate with the network.
Program execution continues, even if the field bus connection is lost. Flash
memory is 32k. An IEC-1131-compatible tool programs the controller so that a
user can download simple logic control into each I/O node.
