Test and Measurement Tips
Rogowski Coil current probes make ac or fast-pulse current measurements
Teledyne Test Tools T3RC Rogowski Current Probes offer broad current measurement ranges and a wide frequency span. Five models are available, providing measurement capabilities up to 6,000 A and with the capability to connect around the leg of a small T0-220 device. The probes connect to any standard oscilloscope via a conventional BNC connection. The […]
Hot topic: How to measure plasma in a fusion reactor
The International Thermonuclear Experimental Reactor (ITER) tokamak is an experimental machine designed to harness the energy of fusion. ITER will be the world’s largest tokamak, with a plasma radius of 6.2 m and a plasma volume of 840 m³. The heart of a tokamak is its doughnut-shaped vacuum chamber. Here, under the influence of extreme […]
Better simulation of IP Multimedia Subsystem functions for 4G/5G terminal development
A Log Import option strengthens the IMS evaluation functions of the Anritsu Signalling Tester MD8475B base station simulator. Using the solution, live-network Wireshark logs are converted automatically to IMS scripts for easy configuration of an automated test environment to replay VoLTE/IMS faults when used with the IMS Basic Script option. Mobile terminal vendors and carriers […]
Thermal analysis software for R&D and science applications
New thermal imaging software for Research and Development (R&D) and science professionals is available for a free trial download. FLIR Research Studio is designed for use across multiple platforms and in 22 languages, to allow R&D and engineering teams to collaborate on thermal data collection, analysis, and sharing. In combination with a FLIR thermal imaging […]
Visualizing phase relationships in capacitors
The ideal capacitor consists of two conductive plates separated by a thin dielectric layer that separates and insulates the two plates from each other so they have no direct or resistive electrical connection. When voltage is applied across the plates, they store the electrical charge. The capacitor may take many forms. If the plates are […]
New 13, 16-GHz scopes excel at handling high-speed serial interfaces
The DPO70000SX Series Performance Oscilloscopes have expanded to include new 13 GHz and 16 GHz models. The new offerings allow engineers to take advantage of the high sample rate and low noise floor of Tektronix’ highest performance family of oscilloscopes at lower bandwidth levels and more affordable price points. The DPO70000SX Series oscilloscopes were initially […]
Op-amps and their most important parameters
The operational amplifier (op-amp) has been one of the most successful integrated circuits. A type of differential amplifier with high gain, the differential inputs and single output enable this small, inexpensive IC to use negative feedback in a wide variety of applications, in which its gain (hundreds of thousands of times higher than the difference […]

How to measure current and energy use accurately
General-purpose test equipment can have trouble measuring small currents, particularly if they only happen briefly. New specialized instruments go a long way toward solving this problem. Matt Liberty | Jetperch LLC The direct measurement of current is difficult. It’s usually impractical to count individual electrons, so the two primary techniques for measuring current actually measure […]
