A PCI Express 5.0 Mini Cool Edge IO (MCIO) interposer works in combination with Teledyne LeCroy’s Summit family of PCI Express 5.0 protocol analyzers. The new interposer enables engineers to test products that incorporate card edge connectors or cabled connector assemblies that utilize the MCIO mechanical connector with PCIe 5.0, NVM Express (NVMe) or Compute […]

Probe kit traces/locates cables in unpowered or active networks
The Digital Tone and Probe Kit (p/n TDG310K1C), now shipping, has an MSRP of $144.95. “The TDG310K1C Digital Tone and Probe Kit allows tracing and locating of single or bundles cables that are connected to unpowered or active networks such as phone lines, network cables or coax cables,” explained George Jang, Platinum Tools product manager. […]
IMS 2022 video: Test equipment
Several test equipment companies demonstrated their latest products for attendees of the International Microwave Symposium.
YouTube videos shed light on frequency and wavelength
Today, an advanced multimeter such as the Fluke 287 in volts mode accurately displays frequency. High frequencies are displayed in a bench-type frequency counter, which can read above 100 GHz. At still higher frequencies, measurements are made indirectly via heterodyning to down-convert the signal. Using a diode or similar device as a mixer, a frequency […]
ESW EMI test receiver bandwidth goes to 1 GHz
The R&S ESW EMI test receiver will offer the possibility to increase its FFT (Fast Fourier Transform) bandwidth to 350 MHz with the new R&S ESW-B350 option, and to a market-leading 970 MHz with the new R&S ESW-B1000 option. This makes the R&S ESW not only an instrument of highest performance in RF, functionality, versatility […]
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 […]
