New updates to the LabVIEW 2019 and LabVIEW NXG programs are said to increase developer productivity through improved visibility in the IDE, powerful enhancements in debugging, and new datatypes to the G-language. Additionally, LabVIEW 2019 addresses a critical pain point for engineers: managing dependencies and versioning with fragmented, non-standardized methods, which perpetuate as challenges in […]
New mmWave test setup designed to accelerate 5G commercialization
A mmWave Vector Signal Transceiver (VST) is designed to address the test challenges of 5G mmWave RFIC transceivers and power amplifiers. NI’s solutions use the mmWave VST, which combines an RF signal generator, an RF signal analyzer and integrated switching with 1 GHz of instantaneous bandwidth at frequencies up to 44 GHz. In addition to […]
Tools for optimizing circuit bias
If a semiconductor or vacuum tube is to accurately reproduce or amplify signals on its input, it must have on its input a non-time-varying dc voltage, i.e. dc bias, the purpose of which is to keep the device in its linear operating range. Otherwise, the input signal to be reproduced may drive the device beyond […]
What’s new with Wi-Fi 6? Focus on high-efficiency
The first wide-spread home electrical appliance was the toaster, and 90% of homes today still have one.[i] Today, wireless connectivity to the internet is as ubiquitous as the electricity was a hundred years ago. Smartphones, tablets, wearables, laptops, televisions, Nest thermostats, Alexa, Google Home, Ring video doorbell sensors, surveillance cameras door locks, smart lighting, and […]
T&M pioneers among lastest group of Inventor Hall of Fame inductees
The latest group of nineteen inductees making up the 2019 Class of the National Inventors Hall of Fame include two pioneers in the test and measurement field. Inductees Jeff Kodosky and James Truchard introduced LabVIEW in 1986 as a graphical programming language that enables user-defined testing and measurement and control systems. It grew to be […]
Synthesized tuning, Part 2: Advanced synthesizers and performance
Part 1 of this FAQ looked at the basic issues and topologies related to the challenge of frequency synthesis. Part 2 continues with advanced approaches and their attributes, as well as general concerns when choosing a synthesizer. Q: Are there other digitally-controlled synthesizer topologies? A: Yes. A widely used one is called the classical phase […]
LabVIEW NXG aims to simplify time-consuming tasks in automated T&M apps
A new release of LabVIEW NXG is designed to simplify the most time-consuming tasks in automated test and automated measurement applications, from setting up and configuring systems to developing test and measurement code and creating web-ready applications. These enhancements help engineers meet challenging time-to-market requirements. “Since the initial launch of LabVIEW NXG in 2017, we’ve […]
RF/Microwave noise, Part 2: Noise temperature and applications
Part 1 of this FAQ looked at the basic specifications of noise factor and noise figure, widely used in RF/microwave system and circuit analysis to predict and assess both requirements and performance. This part looks at the additional parameter of noise temperature, as well as the impact this parameter has on system performance. It also […]
Test and measurement with LabVIEW
LabVIEW is an awesome product created and maintained by National Instruments. It consists of systems engineering relating to test, measurement and control of instrumentation, devices and machinery, and it is currently used worldwide in numerous applications. Rather than endless lines of textual coding, LabVIEW has a simple graphic interface where devices such as an oscilloscope […]
New mmWave radio heads target 5G NR research and system prototyping
Two series of new millimeter wave (mmWave) radio heads for the NI mmWave Transceiver System cover the spectrum from 24.5 GHz to 33.4 GHz and 37 GHz to 43.5 GHz. Both target wireless researchers prototyping 5G New Radio (NR) systems. As the first phase of 5G NR wraps up and the 3GPP finishes defining the […]
