Traditional Instruments: The Antique Collector’s Dream 9
The biggest innovations in instrumentation technology today allow once-separate instruments to work better together, fueling the growth of modular test platforms such as PXI.
User-Programmable FPGAs: The New Frontier of Instrumentation
Engineers are using PXI to replace their traditional spectrum analyzer for prototyping advanced electronic systems, and integrating FPGA technology in PXI to meet high-performance demands.
Curb the Rising Cost of Wireless Production Test
Tomorrow’s wireless test challenges will require a combination of lightning-fast instrumentation, a new approach to wireless test, and the engineering expertise required to put it all together.
5 Things You Didn’t Know RF Signal Generators or Analyzers Could Do
The emerging capabilities of the latest RF signal generators and analyzers are empowering engineers to use off-the-shelf instruments in an ever-expanding field of applications that were once solved by designing one’s own custom instrument.
Falling Wireless IC Costs Intensify Test Challenges 1
The trend of declining wireless IC prices means that test costs must also decline to ensure that products remain economically viable, creating more of a challenge for engineers testing both RFICs and mobile devices
Is There Life After IEEE 802.11ac?
What's the low-down on the new 802.11 revisions, namely 802.11ad, 802.11af, and 802.11ah?
The Importance of Bandwidth 3
The key area of improvement for RF signal generator and analyzer technology has been, and continues to be, wider instantaneous bandwidth.
Zero Span Made Simple
The increasing instantaneous bandwidths of modern signal analyzers combined with the use of more advanced triggering modes has increased the usefulness of zero span measurements.
What To Expect With 5G 1
The desire to further increase data rates in cellular networks is one of the biggest motivations behind today’s ongoing 5G research. Deployment of 5G networks will likely occur well into the future (think 2020), but engineers are researching 5G technologies today.
All About Decibels 5
Although some might find the dB (0.1 Bel) to be confusing, it fundamentally is nothing more than a description of a ratio. Moreover, it is a convenient term that allows us to describe extremely large ratios with simple language using a logarithmic scale.
Understanding IF Bandwidth In RF Signal Analyzers
A basic understanding of the architecture of the modern RF signal analyzer empowers you to optimize its settings for a given measurement.
Understanding Intermodulation Distortion Measurements 2
Intermodulation distortion is an important metric of linearity for a wide range of RF and microwave components. Fundamentally, it describes the ratio (in dB) between the power of fundamental tones and third-order distortion products.
Understanding Your Signal Analyzer’s “Dynamic Range”
David Hall from National Instruments discusses RF Signal Analyzer "Dynamic Range" with the Electronic Design community.
Understanding Signal Analyzer Architectures
The three-stage superheterodye vector signal analyzer uses a reasonably straightforward architecture to cleanly downconvert signals from RF to IF. Understanding these architectures will help you to understand how to optimize your VSA for making challenging measurements such as intermodulation distortion.
VNAs: The Myth, The Mystery, The Electromagnetics 1
VNAs are unique stimulus-response instruments that can make extremely accurate RF power and phase measurements by accounting for various sources of systematic error, the largest of which is electromagnetic reflections.
