Tester evaluates internal battery electrochemical and electrical properties
The BA8100 is designed to test batteries using a complex AC measurement technique known as electrochemical impedance spectroscopy (EIS). Through this technique, the BA8100 derives the internal impedance of a battery across a wide frequency sweep. The acquired data is used to display a graphical representation of electrochemical processes occurring within the battery. The BA8100 […]
Exceeding 100 Gbps with a sub-terahertz 6G testbed
Here’s a look at testing necessary for super-high throughputs involved in the emerging area of 6G. Greg Jue, Keysight Technologies 6G research is in its early stages. The vision for what the International Telecommunication Union calls Network 2030 continues to take shape. While the industry is years away from starting the standards development process, subterahertz […]
Measuring ESR and ESL of dc-link capacitors
Impedance analyzers work better than LCR meters when it comes to sizing up the super-low impedance and inductance of modern power converter capacitors. Tim Ashworth, Meng Li, Zurich Instruments DC-link capacitors are often found in power conversion applications such as inverters, motor drives, medical power supply equipment, and so forth. Consequently, dc-link capacitors often need […]
Automotive cable and harness testing made easy
A hipot tester, switch, and automated software can assure vehicle connectors are safe and reliable. Glen Broderick, Vitrek Inc. Loose or mismatched electrical components cause the highest rate of failures in vehicles. Often harnesses and components are inadvertently pinched, miswired or damaged during installation. Also, cable insulation that isn’t secured can wear through and cause […]
Key considerations for RF power measurement equipment
The choice of power sensor and meter greatly depends on the qualities of the signal being measured. Bob Buxton, Boonton Electronics Today’s complex modulation schemes and pulsed communication modes have brought the need to measure RF power ever more accurately and efficiently. There are multiple technologies available for the measurement of RF power, falling into […]
Automotive data logger captures multiple data streams simultaneously
The X2E XORAYA Z7 Automotive Datalogger can record data from multiple different automotive bus systems simultaneously. All data is logged with a precise, central timestamp with 100-nsec resolution and either saved on the internal SSD or transferred to an external computer system via Ethernet. Optionally, the logged data can be stored on a XORAYA external […]
3U development platform handles SOSA 1.0 and CMOSS designs
A 12-slot, 3U Development Platform is aligned to SOSA 1.0 and CMOSS and features high-speed RF and optical I/O connectivity on a number of key SOSA profiles while supporting both I/O-intensive and compute-intensive processor slots, two switch slots and one PNT slot as part of the test solution. Prior to its official release, the development […]
Radar target generation system cuts down on open-air range tests
The PXI Vector Signal Transceiver (VTS) Radar Target Generation (RTG) system unlocks closed-loop, low-latency, real-time radar test capabilities. The new PXI VST allows engineers to identify and isolate issues before costly open-air range tests, increasing user confidence in radar system performance with accurately calibrated radio frequency (RF) test capability. Today, radar test engineers must test […]
