Dear Sir/Madam
To design complex electronic devices right it is necessary to
validate, verify, and measure the design at every stage. More
and more software is used to do this job but you still need test
&measurement hardware to evaluate whether the final product is
working properly. This newsletter contains some examples for
you. Enjoy!

Mixed-Signal Oscilloscopes
With analogue bandwidths from 200MHz up to 2GHz, a maximum
digital input frequency of 500MHz, and a long memory of
50Mpoints/channel, the MS-500 mixed signal oscilloscope delivers
raw performance for serial-data buses. The mixed-signal
oscilloscope provides up to 36 digital channels. All analogue
and digital channels can capture data at full sample rate for up
to 25ms, simultaneously on all channels.

High-Speed Scopes
The DSA70000 digital-serial-analyser family of
ultra-high-performance oscilloscopes offers test engineers up to
20GHz of real-time bandwidth and a 50Gsample/s simultaneous sampling
rate. The family includes several models: the top-of-the-range 20GHz
DSA72004 is complimented by the 16GHz DSA71604 and the 12.5GHz
DSA71254.

Mixed-Signal Scope
The
SignalXplorer DL9710L is a high-performance mixed-signal
oscilloscope that combines four 1GHz analogue channels (up to
5Gsamples/s sampling speed) with a 32-bit logic input. The
instrument can carry out simultaneous measurement and analysis of
analogue and digital logic signals, with a memory length of
6.25Mwords per channel available.

Exploring LXI's Advanced Capabilities
Paul Franklin and Andrew Creque from
Keithley Instruments
show in their article in EPN that the LXI (LAN Extensions for
Instrumentation) specification help engineers overcoming the
limitations of common test-system architectures in several ways.
LXI systems employ Ethernet LAN for device interconnection so
they don't limit the number of interconnected devices, allowing
easier, less expensive connections. Ethernet networks easily
support physically distributed systems, large data sets, and
high data rates.

Model Behaviour:
Creating Embedded Software Short Cuts
As embedded-system teams race to bring
new products to market, designers are evaluating model-based
development tools to deal with escalating software complexity.
Technical Editor
Warren Webb explains in his article in
EDN how to find the appropriate tools.

Cheap and easy
Inductance tester uses few components
In the absence of expensive test equipment, the circuit in the
Design Idea by
Al Dutcher
in EDN offers a simple and rapid alternative method of measuring
inductance. Its applications include verifying that an
inductor’s value falls close to its design parameters and
characterizing magnetic cores of unknown parameters that
accumulate in most engineers’ collection of miscellaneous
components. As designed, the circuit tests most inductors for
use in power supplies and many inductors for RF circuits.

Oscilloscope helps
obtain Bode plots in non-50Ω environments
A
Bode plot can simplify characterization of an active or a passive
network by showing frequency and phase representations of the
network’s transfer function, T.
Antonio Eguizabal from Freescale shows
in his Design Idea in EDN
an
alternative to building or purchasing custom buffer amplifiers, by
using the near-ideal amplifiers in an analogue oscilloscope that
provides a vertical amplifier output on its rear panels—for example,
the venerable Tektronix 465B.

ESL Design and Verification, by Grant Martin et alElectronic
System Level (ESL) design has mainstreamed – it is now an
established approach at most of the world’s leading
system-on-chip design companies and is being used increasingly
in system design. This book offers a true prescriptive guide to
ESL that reviews its past and outlines the best practices of
today.
