       Four Steps for Making Better Power Measurements 

Before selecting a power meter and its associated sensors, it's 
important to understand the factors that can influence the quality of 
your power measurements.  These factors affect the accuracy, economy, 
and technical match to your application.  Click on the link to learn

When Legends Are Born

The August issue of parent magazine Microwaves & RF carried the first 
installment of the Microwave Legends, listing 45 people, places, and 
things that have had an impact on the RF/microwave industry. First 
off, apologies to anyone who felt slighted by the list, thinking they 
should have been included. It was not meant as a popularity contest. 
The list was nominated by readers, and final voting was performed by 
readers. We editors did some "compiling," but little "steering."

As with other "hall of fame" type endeavors, this one will have its 
"add ons" each year, as we seek to increase the initial list of 45 by 
another 5 noteworthy people, places, or things each year. One of the 
original nominees, for example, was the Anzac catalog. It was a 
classic in its time, and a true reference source in this industry for 
any engineer needing high-frequency components. 

So, don't feel slighted. Instead, get a head start on your nominations 
for 2007 by sending me your suggestions, to mailto:[email protected]

FreeWave Launches Spread-Spectrum Radio Modules

FreeWave Technologies has developed a series of board-level 
spread-spectrum radios that operate in the 2.372 to 2.400 GHz range. 
Well suited for NATO and European allies, the secure frequency-hopping 
radio modules are ideal for original-equipment-manufacturer (OEM) 
applications. They feature a 32-b CRC for error-free communications, a 
20-mile line-of-sight range, and 115.2-kb/s true data rate. The 
versatile radio modules can operate with voltages from 9.5 to 30 VDC.

LXI PlugFest Features Real-World Testing

Held this past July 25-27 in Cleveland, OH, the LXI Consortium's 
latest PlugFest featured more than 50 attendees and included 
real-world testing of products meeting Class A and Class B LXI 
requirements. Products for Class A include time synchronization via 
the IEEE 1588 precision time protocol as well as a hardware trigger 
bus. Sponsored by LXI member Keithley Instruments, all of the tested 
products are expected to receive certification shortly, bringing the 
total number of LXI-certified products to more than 150. The testing 
process also included interface bridges that enable integrators to 
create "hybrid" systems that utilize non-LXI equipment alongside 
LXI-compliant devices. This capability will help system creators 
leverage their existing investments - and expertise - in other 
architectures such as GPIB, VXI, and PXI. The next PlugFest, to be 
hosted by LXI member The MathWorks, is scheduled for October 17-19, 
2006, in Boston, MA.

TensorComm Files 75th Interference Cancellation Patent

Spectral-efficiency specialist TensorComm announced the filing of 
their 75th patent related to interference cancellation, specifically 
for the application of their Interference Cancellation Technology 
(ICT) to networks deploying MIMO. The firm's ICT is designed to 
improve the performance and data throughput of 3G networks 
(CDMA2000/1xEV-DO and WCDMA/HSDPA) and is now positioned to apply the 
same types of benefits to emerging 4G networks. The receiver 
technology, which cancels interference from all traffic channels and 
interfering sources, operates with both base stations and mobile 
devices, and is suitable for single- and multiple-antenna receivers.

DAC Synthesizes 1-GHz Bandwidth

Maxim Integrated Products has developed a digital-to-analog converter 
(DAC) capable of 2.3-GSamples/s, 12-b performance. Model MAX19692 can 
directly synthesize signals with as much as 1 GHz bandwidth at 
frequencies from DC to 2 GHz. The DAC features a -68 dBc spurious-free 
dynamic range (SFDR) at 1.2 GHz. The device operates from 3.3 and 1.8 
V supplies while consuming only 950 mW power. It is supplied in a 11 x 
11 mm 169-CSBGA package.

Instruments Add Data Streaming To RF Measurements

National Instruments has introduced a new RF vector signal analyzer 
and two intermediate-frequency (IF) digitizers that support continuous 
streaming of high-bandwidth RF test data across high-speed buses, such 
as PCI and PXI, directly to a personal computer (PC). The model 
PXI-5661 2.7-GHz vector signal analyzer offers a 20-MHz instantaneous 
modulation bandwidth and built-in burst trigger. The NI 5142 IF 
digitizers are available in PXI or PCI format, each with two 14-b, 
100-MSamples/s channels. According to Tim Dehne, NI senior vice 
president of engineering, "These new RF and IF products represent a 
shift in the way communications systems are designed and tested," said 
"By streaming RF or IF data across high-speed buses directly to a PC 
for processing, the challenge of developing a communications system 
now falls on software." The company also supplies LabVIEW software for

Keithley Offers Remote-Testing Training Course

Keithley Instruments is offering a two-day course on September 14 and 
15, 2006 in Cleveland, OH on the use of National Instruments' LabVIEW 
software for remote control of multiple-vendor test instruments, 
"Optimizing Remote Control of Instruments in a LabVIEW(R) 
Environment." Attendees will learn how to assemble and configure 
instruments from a variety of vendors into an efficient test setup and 
control all of them from a single software interface. The course, 
which is not intended for production testing, consists predominantly 
of practical exercises in a lab setting, plus short lectures on a 
variety of related topics.
