From Bob Helsel, Editor of the PXI Newsletter:

Welcome to the May 2015 edition of the PXI Newsletter.  Our intent is to educate and inform you about how the PXI standard is being used in modular test systems for a wide variety of industries.

In the New PXI Products section, we are showcasing PXI products recently released by members of the PXI Systems Alliance.

Our thanks go to National Instruments, the sponsor for this month's issue.

Designing your first PXI test system? Start inside out.

by Larry Desjardin, Modular Methods

I’ve written several tutorials in the past on how to integrate PXI and AXIe modular systems, and how to combine them with traditional instruments based on LXI. A key concept in doing so is to think inside out. Let me tell you what I mean.

About to select the products for your first PXI system? Start on the inside, with the modules and software.

A logical method might be to choose a chassis and fill it up with modules. You’d then add a controller and software. While this may be logical for the actual integration, it is not the optimal process for choosing products or designing the system. You should design the system starting with the modules and software first, and then choose the controller and chassis. I’ll describe each step, and how each leads to narrowing your choices for the next steps.

Mulit-port and Multi-site Test Optimization Techniques


Submitted by Keysight Technologies

With the trend towards adding more ports on components, accurate and fast multiport network analysis is required. Optimizing your vector network analyzer (VNA) configuration is critical to minimizing manufacturing cost-of-test. This application note provides an overview of multiport and multisite test capabilities, how different multiport test solutions compare, and what considerations need to be made when configuring a multi-site test station.

5 Things You Didn't Know About Your PXI Chassis
(Part 1)



Submitted by National Instruments

Here are 5 things you probably don’t know your PXI chassis offers you.

1. Fan Module LED Indicators

The PXIe-1085 features three field-replaceable fan modules on the rear of the chassis that cool the power supply and instrumentation. The LED at the top of each fan module indicates if the fan is operating normally (green) or if it has failed and needs to be replaced (red).

If one fan fails, the two remaining fans switch to High to compensate. Because the fans are ”hot swappable,“ you can change the faulty fan with a new fan while the chassis is running. If two fans fail at the same time, the chassis shuts down to protect the controller and modules in the system.

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):

NI PXIe-2737 Matrix Switch 
The NI PXIe-2737 is a high-density matrix switch module designed for routing signals within automated test systems and is ideal for applications that would benefit from predictive maintenance features to help minimize system downtime.

Keysight M9451A PXIe Measurement Accelerator
The M9451A PXIe Measurement Accelerator, a high performance FPGA processing card, speeds characterization for RF power amplifier test.With the M9451A, closed/open loop digital pre-distortion (DPD) and envelope tracking (ET) measurements can be made in tens of milliseconds for up to a 100 times speed improvement.

Signal Processing Devices Data Acquisition Platform - ADQ14
The highest performance data acquisition platform available, featuring Xilinx’s Kintex 7 open FPGA
This is a unique and compact multi-channel 14-bit digitizer which offers sampling rates up to 2 GSPS. The ADQ14 is the first digitizer from SP Devices to host a Xilinx Kintex-7 FPGA which is open to the

SMH Technologies FlashRunner FR PXI A3 
FlashRunner FR PXI A3 is a universal high-integrated in-system parallel programmer for PXI and CompactPCI systems. FlashRunner FRPXIA3 is designed for programming multi-PCB panel assemblies, and it is based on FlashRunner technology, the fast and reliable programming system for Flash-based microcontroller and serial memories.

Pickering Interfaces Expands Range of 16 Amp PXI Switching Solutions
16 Amp PXI power multiplexer (model 40-662) – available in seven configurations ranging from 4-off 2:1 multiplexers to 1-off 16:1 multiplexer.
16 Amp PXI power matrix (model 40-552) – available in four configurations with matrix sizes of 8x2 and 4x4 and the ability to expand the matrix size with the Y-Axis loop-thru connections. For example, 8x4, 12x4, 16x4, etc. (with 4x4 matrices) or 16x2, 24x2, 32x2, etc. (with 8x2 matrices).
