Securing Your Test System


Test systems, like other industrial equipment, are vulnerable to cyber attacks. That requires a phased approach to cyber security, addressing the most likely threats first and communicating with suppliers to understand threats upstream in the supply chain. To read more, click here. » read more

Don’t Let FPGA Compiles Be a Bottleneck


Wireless engineers often want to use over-the-air signals to go from concept to prototype. Software defined radios (SDRs) such as the USRP (Universal Software Radio Peripheral) device provide a flexible solution to meet that need. With today’s applications demanding higher bandwidths and lower latencies, more of this signal processing needs to be implemented on the FPGAs of SDRs. However, wir... » read more

Astronics Ballard Technology OmniBus II PXI Express Product for Avionics Test


The OmniBus II PXIe databus interface products combine the standard PXIe interface with MIL-STD-1553 and ARINC 429 Avionics Data Bus interfaces. Interface cards can be ordered with either MIL-STD-1553 only, ARINC 429 only, or both interfaces on the same card. The PXIe interface includes a PCIe x1 interface to the controller as well as support for PXI clock, timing and trigger signals. The inclu... » read more

Design Challenges Of Next-Generation AESA Radar


Phased-array antennas, first used in military radar systems, are gaining in popularity for a variety of applications with new active electronically-scanned arrays (AESAs) being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed, meeting size and performance requirements are critical. To support AESA radar development efforts, electronic design autom... » read more

Improving 5G


The Challenge: By 2020, Cisco forecasts that 5.5 billion people will own mobile phones. In the United Kingdom alone, tens of millions of these mobile users will each consume 20 GB of data per month and use more than 25 different smart devices in their daily routines. Factor in data-hungry applications like 4K video, driverless vehicles, smart factories, and broadband access expanding to the mos... » read more
