Langer EMV-Technik Announces PA 2522 Compact Preamplifier for Low Signal Measurements from 10MHz up to 22GHz

The new PA 2522 preamplifier from Langer EMV-Technik can be used to amplify weak measurement signals from near-field probes, connected to the 50Ω input of a spectrum analyzer or oscilloscope. It stands out because of its low noise behavior and a constantly high dynamic range over an extremely wide frequency range, from 10MHz to 22GHz. The preamplifier is powered by the included power adapter.

Practical Test & Measurement: ANC Headset Testing

Exploring some pressing topics in headphone technology, in this article Hans W. Gierlich addresses the requirements for effective performance testing of communication headsets that use active noise cancellation (ANC) technologies, test setups, testing equipment, and setup conditions needed to correctly assess ANC performance. From the right choice of artificial ears and the latest ITU-T recommendations in that domain, to ANC performance measurements and talk-though performance. This article was originally published in audioXpress, June 2022.

Acroname Launches First Programmable USB Type-C Hub Designed for USB-PD Debug and Validation

USB Specifications, unified by products using a USB Type-C connector, commonly called USB-C, promise standardized power and data delivery. Unfortunately, poorly tested devices in the market can make USB-C systems unpredictable, expensive, and frustrating to consumers. Improving USB-C testing is critical to delivering on the “one connector to rule them all” promise of USB-C. Acroname's new USBHub3c makes testing USB-C devices easier, safer, and cheaper.
