The 42-927 PXI chassis from Pickering Interfaces saves test-rack space by accepting up to 20 PXI or PXIe instruments and switch cards. No matter how many instruments they hold, large, automated test systems always take up too much floor space. While test racks may have increased in density since the PXI bus was introduced in […]

What’s the difference between a PCIe analyzer and jammer?
Protocol analyzers and jammers let you test and troubleshoot the performance of PCIe interconnects. From generation to generation, PCIe speeds double. Today’s protocols can be challenging to test and qualify. In addition, advanced applications such as the non-volatile memory express (NVMe) solid-state drive (SSD) memory protocol developed specifically for use with PCIe require sophisticated testing […]
Raspberry Pi for DAQ
Though they are more closely associated with the maker space, Raspberry Pi boards can be effective at handling stringent industrial measurements. Steve Radecky, Measurement Computing Corp. Originally designed to be a cheap, almost disposable computer, Raspberry Pi was created to get kids interested in programming. Since its introduction in 2012, Raspberry Pi has become the […]
FIPS 140-2 security testing for wireless medical devices
Design engineers should be aware of several testing issues surrounding encryption standards designed to protect data from bad actors. Jay White | Laird Connectivity The bad guys don’t care about your social security number and credit card numbers as much as you might think. Stolen security numbers are almost literally a dime a dozen on […]
Interoperability testing for the Internet of Things
The Internet of Things might also be thought of as the internet of interoperable things. A systematic testing regime can help uncover problems when devices work in concert. DELMAR HOWARD, INTERTEK GROUP PLC The Internet of Things (IoT) is growing at an exponential rate. In three years, the number of IoT-enabled products is expected to […]
Testing and debugging the I2C digital data bus
“Bus” is an old term derived from conductive elements that are part of an electrical distribution system, generally referring to short specialized conductors separate from the overhead or underground cable. Typically, the old-style buses consist of bare copper bars, often having a rectangular cross-section, firmly mounted in an enclosure and capable of carrying current at […]
Miniature data recorder targets harsh, wet and dusty uses
The SLICE IP68 data acquisition system is designed to measure physical signals in challenging test environments. With an ultra-small footprint of only 60×60 mm, SLICE IP68 can embed in most test articles with size and mass constraints. The rugged enclosure features special sealed layers and IP68-rated connectors and meets MIL-STD-810G for temperature, altitude, shock and […]
Basics of the FlexRay Bus
As automobile development has continued apace, some new highly complex and critical subsystems have emerged. Simple networks such as CAN Bus and LIN Bus have long handled communications among controllers and electromechanical automotive systems, but an enhanced communication bus eventually became necessary to handle higher-bandwidth connections. Accordingly, a consortium developed standards for what came to […]
PocketPico P200 PowerMate
PocketPico P200 PowerMate energy optimization instrument is designed specifically for embedded systems engineers and other low power electronics developers. PowerMate accurately measures current from 10 nA to 30 mA in a single measurement range and charts system energy usage over time. Developers can optimize both hardware and software for maximum energy efficiency within any development […]
