Antenna test system enables temperature-controlled measurements, polarization access
The R&S ATS1500C antenna test system from Rohde & Schwarz offers a new temperature test option and a new feed antenna. These additional features enable temperature-controlled measurements in a wide temperature range as well as parallel access to both polarizations, increasing test efficiency and flexibility. The movable R&S ATS1500C is a compact antenna test range […]
Protocol test system handles USB Power Delivery, USB Type-C, USB 3.2 link layer compliance testing
The Voyager M4x Analyzer/Exerciser system has been approved by the USB Implementer’s Forum (USB-IF) for USB Power Delivery (USB PD), USB Type-C Functional and USB 3.2 Link Layer compliance testing. The Voyager M4x also supports USB4 logical and protocol layer compliance allowing this single test platform to address the most critical technologies within the USB […]
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 […]

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 […]
