A general measurement technique for determining RF immunity 
Oct 1, 2005  By Arpit Mehta
This article describes a generalized technique to measure the RF immunity of a circuit. It defines a standard and structured test methodology aimed at establishing adequate repeatability of the test results for qualitative analysis....

Goodbye ESN, hello MEID: MEID as a solution to ESN exhaustion 
Sep 1, 2005  By Mike Keeley
Electronic serial numbers have served CDMA and other wireless technologies well, providing a mechanism to uniquely identify each mobile device. But the impending exhaustion of available ESNs necessitates a replacement. That replacement is the mobile equipment identifier....

Arbitrary/function generator combines three products into one 
Aug 1, 2005 
Implementing a 0.18-micron CMOS-based generator-on-a-chip ASIC device, Tektronix has readied a new family of arbitrary/function generators that establishes a new benchmark in performance and ease of use. ...

NxTest and the development of synthetic instrumentation 
Feb 1, 2005  By Marvin Rozner
You may have been hearing the term synthetic instrumentation used lately to describe a new test system architecture...

Detecting interfering signals and mitigating them 
Jan 1, 2005  By Steve Thomas
Interfering signals close to a carrier can be sources of interference that are difficult to detect. Field technicians must be able to identify and mitigate such interfering signals that can be less than 1 kHz apart and have a 60 dB difference in amplitude. The article discusses the type of performance necessary in a test instrument in order to identify interfering signals and track them down to their sources....

Direct-sequence UWB signal generation and measurement 
Nov 1, 2004  By Peter Cain
This article discusses how to generate and measure ultra-wideband signals to design and test the performance of radio receivers handling UWB signals. A number of novel techniques, such as pulse shape recovery and frequency measurements on sub-nanosecond pulses, are described using modern test equipment....

Future military test systems hinge on synthetic instrument development 
Nov 1, 2004  By Gene Heftman, Contributing Editor
Ten years ago, the Department of Defense authorized the Navy to begin developing new types of automatic test systems to test military and...

Synthetic Instrumentation: Contemporary architectures and applications (Part II) 
Nov 1, 2004  By Peter Pragastis, Iqbal Sihra and Michael N. Granieri
Synthetic instrument implementations often come in a variety of flavors; there are many ways to build an SI mousetrap...

Evaluating the impact of pulsed phase noise on 802.11a/g OFDM transmit performance 
Nov 1, 2004  By Carsten Andersen and Dick Walvis
Many different sources can degrade 802.11a/g transmitter performance non-linearities, I/Q imbalances, additive noise, transient effects but pulsed phase...
