Common Algorithms Enable Measurement Consistency
from R&D Through Production

Submitted by Agilent Technologies

Test requirements for complex wireless applications evolve from “unbounded” in R&D to “just enough” on the production line. Creating a test system to meet these varied requirements, while also addressing business drivers, often requires an optimal combination of benchtop and PXI test equipment. In some cases, PXI test instruments may offer the most appropriate test solution, while in other cases, a mix of benchtop and PXI might be more appropriate. However, integrating instruments with different form factors into the same test environment can result in inconsistent measurement results unless measurement platforms and the associated measurement software are well-harmonized.

One PXI vendor meets this challenge by incorporating the same measurement algorithms into its firmware and software, resulting in trusted, consistent measurements and analysis that can be easily correlated at multiple points in the product development cycle, across benchtop and PXI form factors. 


Paving the Way for 5G Wireless
With mmWave Cellular Systems


Submitted by National Instruments

Wireless consumers’ insatiable demand for bandwidth has spurred unprecedented levels of  investment from public and private sectors to explore new ways to increase network capacity and meet escalating demand. Industry analysts predict demand will outpace capacity; it’s simply a matter of when. Wireless researchers continue to present ideas to address capacity challenges and explore network topologies that not only tackle capacity concerns but also offer features and functions never thought possible. Transitioning from concept, which is largely a software exercise, to a working prototype with real signals and waveforms requires extensive investments in time and money, and has been an impediment to the adoption of new technologies and capabilities. Design approaches that embrace software reconfigurability with an accelerated path to prototyping can expedite the design, exploration, and deployment of these technologies in new and exciting ways.

1. Meeting the Demand With mmWave Bands
The highest radio frequency band in practical use today is mmWave or EHF (Extremely High Frequency), which is the next band above microwave. It includes frequencies from 30 to 300 GHz. Because this band has a wavelength of between 1 and 10 mm, it has given rise to the name millimeter band or millimeter wave, also called mmWave or mm wave.

To increase spectral efficiency of current commercial cellular systems, researchers are exploring physical layer techniques such as massive multiple input, multiple output (MIMO); interference coordination; network densification; and many others. In addition to these techniques, availability of large chunks of spectrum in licensed and unlicensed mmWave bands (above 28 GHz) have generated interest from researchers, in both academia and industry, as a way to meet the multigigabit per second data rate demand of 2020 and beyond.


2014 Global Frost & Sullivan Award
for Growth Excellence Leadership in PXI


Submitted by Agilent Technologies

Frost & Sullivan has recognized Agilent Technologies with the 2014 Global Frost & Sullivan Award for Growth Excellence Leadership in PXI instrumentation, noting that Agilent’s strategy of offering customer-centric, market-specific solutions, built upon its expanding modular product portfolio, has driven its success in PXI, resulting in increased market share from < 5 percent in 2010 to 13.3 percent in 2013.

New PXI Products

The PXI platform continues its explosive growth with many new product introductions. New products introduced in the last three months include (listed in the order received):

Chroma ATE High Precision Source Measurement Unit (SMU) 52405e Series
Chroma ATE, one of the world leading suppliers of electronic test, measurement and automation production, has announced the SMU cards in its line of PXI Express products. The 52405e is a high precision source measure unit with dual SMU channels.

Pickering Precision Resistor PXI modules
Pickering Interfaces has introduced an expanded range of precision resistor PXI modules. The 40-297 has been expanded to increase the number of different versions available from 6 to 42 while the new 40-293 offers a lower cost and lower density option for systems requiring fewer resistor simulation channels.

VTI Instruments SMX-3276 – Versatile PXI Express 152 Channel 300V/2A Multiplexer
The SMX-3276 is a 152 channel, 300V/2A, 3U PXI Express multiplexer module designed for the scanning of multiple points to a common bus. The module can be reconfigured under program control for 1, 2, or 4-wire configurations providing the versatility necessary to be used in various applications.

National Instruments PXI-1470 Phase Matrix 26.5GHz PXI Vector Signal Analyzer
National Instruments (NI) introduces the NI PXI‑1470, a PXI-based 26.5 GHz vector signal analyzer (VSA).  This is the latest addition to the NI RF-hardware family of fast, flexible, and accurate RF hardware powered by NI's LabVIEW software to meet the ever-increasing demands of the RF and microwave industry.  The NI PXI‑1470's frequency coverage is between 50 MHz and 26.5 GHz and includes hardware-filtered preselection circuitry for multi-signal and high-power environments.
