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

12 Important Considerations When Migrating to the Digital Pattern Instrument


The PXI Digital Pattern Instrument brings ATE-class digital to the PXI platform through features and programming that are familiar to semiconductor test engineers. Those features not only come through in the hardware of the instrument, they also appear in the NI-Digital Pattern Driver and Digital Pattern Editor. The digital pattern instrument represents an improved experience to previously exis... » read more

Standardizing Platforms From Characterization To Production


In 1983, the first commercial mobile phone retailed for $3995, almost $10,000 in today’s economy. It supported a single band, weighed almost a kilogram, and was about the size of a brick. Two decades later, a quad-band “world phone” costs a few hundred dollars. Even a basic mobile phone that supports over 20 cellular bands, in addition to Bluetooth, Wireless LAN, and GPS technology, ... » read more

When Exposed To IoT, Big Iron ATE Will Rust


When the first “smart” refrigerators were released in the early 2000s, consumers weren’t sure what to do with them. When Nest released the smart thermostat, though, a revolution happened. Humans were taken out of the loop because the thermostat learned on its own about desired temperature and how quickly it could cool or heat a house. And it could synchronize all of this better than a hum... » read more
