What’s all this Helmholtz coil stuff?
The Helmholtz coil was not devised to create a magnetic field, but to cancel it. The Helmholtz coil actually consists of two identical circular air-core coils, large enough to contain the work under study. The coils are situated along a common axis that extends through the experimental area. The distance between the coils is equal […]
Sorting out balanced cables and differential signaling
Lines carrying symmetric signals, i.e. those with opposite polarities but with equal amplitudes on each line are commonly called balanced. But the correct term is differential signaling. While balanced lines and differential signaling may be used together, they are actually quite different. The key point that distinguished balanced lines from single-ended lines is that both […]
Intrinsically safe meters simplify mechanical, electrical bond testing
The TEGAM 700 series of bond meters now include two handheld measurement tools. The TEGAM 720A and TEGAM 730A bond meters are suitable for use in the manufacture and maintenance of automotive, aerospace, renewable energy equipment and other applications in which testing of the integrity of mechanical and electrical bonds is a critical requirement. The […]
Ultra-wideband, omnidirectional antennas optimized for radial isotropic measurements from 150 MHz to 18 GHz
Aaronia OmniLOG PRO Omnidirectional Antennas are compact, ultra-wideband omnidirectional antennas suited for radial isotropic use from 150 MHz up to 18 GHz, encompassing most RF sources such as LTE, GSM, UMTS, WLAN, etc. These cost-effective antennas are specified for 1 W cw receive and 100 W cw high-power transmit, making them candidates for broad-range spectrum […]
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.
