More Test in Less Space:  Driving Down the Size of Test

Submitted by Keysight Technologies

As silicon wafers, wireless devices and military systems have increased in complexity, multi-port vector network analysis with S-parameters has become an indispensable tool. A few years ago, vector network analysis with four-port capability was a common need. A variety of next-generation products then entered the market, requiring 8-port measurements, and some manufacturers responded. The trend continued with the following generation requiring 16-port capability, and 32-port requirements are on the near horizon.

A three-part test challenge: Reducing the size of VNA test
systems while increasing capacity and capability

Along with this trend, many organizations are seeking to drive down the size of test with more capability per cubic inch in their test stations. This is a subset of the larger need to drive down the cost of test to help ensure ongoing profitability as prices erode in wireless communications or as business models change in aerospace and defense.


5G to Disrupt the Test Equipment Market

by Larry Desjardin, Modular Methods

The coming 5G wave is set to not only disrupt the communications sector, but also the test equipment that serves it.  While some traditional instrument product categories may be utilized in the development of 5G, the real heavy lifting will be performed by instrumentation not yet invented. The combinations of frequency, spectrum width, data rates, and multi-antenna architectures are simply not present in today’s instruments. But one thing is clear: modular instruments will play a primary enabling role for 5G.  To explain why, let me first explain what 5G is all about.

What is 5G?

Simply put, 5G is the next generation cellular standard, the fifth generation.  The first cell phones were analog-based, such as Motorola’s AMPS (Advanced Mobile Phone System).

5 Things You Didn't Know About Your PXI Chassis
(Part 2)

Submitted by National Instruments

After reading part one of this three part series, you now know that your PXI chassis has hot-swappable cooling fans, full-hybrid peripheral slots, and field-replaceable power supply that can be changed in minutes without removing any I/O connections. But even still, a PXI chassis has a lot more functionality.

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

1. Differential Star Trigger
The system timing slot of the PXIe chassis has three dedicated differential pairs that you can use for high-speed triggering, synchronization, and clocking with a maximum slot-to-slot skew of 150 ps.


Thanks to all our readers.

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):

VPC i2 MX - Scalable... Configurable... Modular
The all new i2 MX connector is your new wiring solution for improved configurability and horizontal stackability. The i2 MX allows for multiple modular inserts including: Micro & Mini Power and Coax, QuadraPaddle™, TriPaddle, and VTAC (HSD). It can also be used within multiple VPC interfaces, including the 90 Series adding the capability to interconnect with your PXI instrumentation.

AIT Shared Memory Network PXI Express InterfaceBuilding on AIT’s complete line of avionics data bus test instruments, the new PXIe-SMN provides an interface to a high speed (2.125 Gbps), low latency, optical shared memory network.

NI PXIe-4463 Dynamic Signal Generator
The NI PXIe-4463 dynamic signal generator offers best-in-class dynamic range and THD+N for audio, acoustic, and vibration applications. It provides the high precision and dynamic range necessary for the most stringent audio generation requirements in a modular form factor. 

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.
