From Aaron Hall, Editor of the PXI Newsletter: |
Welcome fellow Test & Measurement professionals,
Thank you to all those who complete the survey in our last newsletter. Bob Stasonis, the president of the PXI System Alliance, mention in the last newsletter that we would include more survey throughout the year. Please take some time to fill out the new survey linked in this newsletter. You can click on the picture to the right for our latest survey.
February has been an exciting month in the mobile market and the world. The Mobile World Congress was scheduled to meet in Barcelona February 24-27 to bring together many of the world leaders in 5G technology. Due to the Corona virus (COVID-19) outbreak, many of the largest vendors cancelled their appearance and the event was ultimately cancelled. Even though the event was cancelled, many of the announcements that were planned for the Mobile World Congress will be made in the next few weeks.
We hope everyone stays healthy and enjoys the articles presented along with the New Products section in this month's newsletter.

Understanding Programmable Resistors for Sensor Simulation in Test
|
By Pickering Interfaces
If you think about it, sensors control much of our daily lives. Sensors ensure that the food in your refrigerator stays cold, count your steps on a smartphone when out for a run, and even protect you in an automobile accident. So many devices in our personal lives as well as in business, aerospace/ defense, medical, and other niches contain sensors.
All these sensors add a layer of complexity to your test strategy, as you need to simulate them when testing the circuit board that makes decisions based on a sensor's response. Since it is usually not practical to incorporate actual sensors into a test fixture, Pickering Interfaces has created external hardware that is designed to replace these sensors in an automated test program. In this paper, we will talk about sensor simulation, how to select these products, and show a couple of examples where sensor simulation made perfect sense. Given Pickering's history of more than 15 years designing programmable resistors, we have the expertise and product depth to play an important role in testing sensor-driven products.

Yamaha Fine Technologies and Keysight Technologies Achieve 100% High-Frequency PCB Characterization
|
By Electronic Design
Modern printed circuit boards (PCBs) constructed from flexible liquid crystal polymer (LCP) and polyimide (MPI) substrates present unique test challenges for PCB manufacturers. These PCBs require precise high-frequency measurements of high-speed transmission lines on the circuit boards. Yamaha needed to integrate instruments that make precise high-frequency measurements with its PCB test equipment to support 5G reliability.
Learn about a complete, fully traceable high-frequency PCB test solution featuring Yamaha's PCB tester and Keysight's PXI vector network analyzer.

Where Does 5G Conformance Testing Stand in 2020?
|
By Electronic Design
The 5G test and conformance era is far more challenging than 4G wireless amid a broad range of new services and technology paradigms. There is a large matrix of test cases that vary widely, and these changes reinforce the importance of adequately validating the device performance on 5G networks as specified in the New Radio (NR) standard.
The 5G conformance test spans RF characteristics, radio resource management (RRM), and communication protocol suites, and that calls for flexible test solutions that can eventually be customized for specific use cases and certification requirements. At the same time, it is also critical that both chipsets and devices are rigorously tested under linear and nonlinear conditions across the entire workflow, from design validation to product manufacturing.
There are other pressures as well when it comes to accelerating the conformance to advance 5G commercialization. For instance, network operators, as well as chipset and device manufacturers, are striving to ensure successful device testing and acceptance on the first attempt. But that is easier said than done.
