Power choke testers measure up To 4 kA/7.7 kJ
The ed-k DPG Power Choke Tester family is a unique series of innovative measurement instruments for inductive power components, using currents up to 4 kA and pulse energy up to 7.7 kJ. The DPG series uses a large-signal impulse measuring method to provide a complete inductance curve as a function of the current L(i), or […]
Scanning for defects with sound waves
High-speed, non-destructive ultrasonic scanning identifies minute defects in specialty metals and alloys using advanced, phased array scanning acoustic microscopy (SAM). By Hari Polu, President, OKOS High-purity metals and alloys such as aluminum, zinc, cobalt, copper, titanium, zirconium, molybdenum, magnesium, and stainless steel are central to many different industries, including electronics, aerospace, and medical devices, among […]
The difference between impedance analyzers and network analyzers
At first glance, impedance analyzers and network analyzers seem to do the same thing: Describe the impedance of whatever is connected to their inputs. This statement is true as far as it goes, but as you might expect, there are significant differences between the two types of instruments. Here’s a review of the basics. There […]
PCI Express 5.0 interposer works with protocol analyzers
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 […]
