PXI – Continued Success Delivering High-Performance, Functional Test Solutions

 

By Loofie Gutterman, President, PXISA
and President, Marvin Test Solutions

(First published in Electronic Product Design & Test magazine)

PXI is now in its 18th year as a standard and we continue to see the PXI platform expanding into ever broader applications. Once considered a solution for only low cost and non-complex test applications, PXI products and solutions have evolved considerably.

Today, PXI-based solutions are delivering the performance and capabilities required for testing mission critical, high performance devices, modules, subsystems, and systems for a wide range of applications including military, medical, automotive, semiconductor, and the aerospace markets. The many advancements in digital, RF, and microwave PXI instrumentation have all contributed to PXI’s ongoing success, growth, and acceptance in the functional test market. Performance test solutions based on PXI have become the rule rather than the exception for most test applications ranging from manufacturing and depot testing through portable field and
flight-line test applications.

Alternative to Custom Mechatronic Test Development


Submitted by Keysight Technologies

Automotive and transportation test system are different from most device test solutions because they require a combination of mechanical, electronic and software technologies, known in the industries as “mechatronic” test solutions. The mechatronic test capabilities are required to test electronic control units (ECUs) such as electronic parking brakes, anti-lock brakes or power steering. The ECUs are tested in true-to-life simulated environments. Typical measurement and control instruments include digital I/Os for open/short tests on ECU connector pins, or to determine ECU pin states, and digital multi-meters for resistance and voltage measurements. High power loads and switches are also needed to emulate different types of automotive source and sensor signals. Beyond measurements, automotive test systems must also communicate with the ECUs to verify functionality using the controller area network (CAN) bus serial protocol.  These unique test needs are often addressed by test development engineers with a custom solution. Engineers, who are faced with the ever growing demands to reduce cost by minimizing overall test size, reducing test development time, test time itself, and test re-configurability are learning to take advantage of what modular, (i.e. PXI, AXIe, VXI and VME) test systems have to offer.

This article discusses how the unique needs of automotive mechatronic test can be addressed with a modular test solution.

Building a High Performance Data Acquisition System
in a PXIe Chassis Using XMC Modules



Submitted by Innovative Integration - A Molex Company

When designing a high performance data acquisition system, a significant decision is what chassis form factor to use. A rackmount 19-inch chassis comes to mind as a good generic solution, and the PXIe version seems like a good candidate as it is standardized, reasonably priced, and available from multiple vendors. The only significant concern is that native PXI/PXIe modules are generally aimed at the testing market, which means they tend to have lower throughput, with less processing power than needed in high performance data acquisition systems.

This concern can be addressed by XMC modules which provide a universe of high performance data acquisition functions, featuring higher sample rates, and greater processing power with on board FPGA’s, than typical PXI/PXIe modules. An XMC module can be incorporated into a PXIe chassis using a PXIe to XMC Adapter which plugs into the chassis and is a carrier for the module.

Highly Parallel Wafer Level Reliability Systems with PXI SMUs

Overview
Reliability testing has long served as a method of ensuring that semiconductor devices maintain their desired performance over a given lifetime. As IC manufacturers continue to introduce new and innovative processes with decreasing device geometries, they need to ensure the additional complexity from these changes does not affect the long-term reliability of their ICs.

Additionally, major technology trends in autonomous driving, cloud-based data storage, and life sciences are forcing IC suppliers to provide higher assurances of product reliability to their customers who work on mission-critical applications. 

These two trends are driving semiconductor manufacturers to vastly increase the amount of reliability data they collect and analyze while decreasing the cost of test. When faced with this problem of more data at a lower cost, many reliability engineers find they cannot solve it using traditional reliability solutions, so they are turning toward modular, flexible solutions that can scale to fit their needs.
