RIGOL Technologies announces a significant addition to its oscilloscope portfolio with the introduction of the New 7000 Series Digital Oscilloscope. The instrument offers 10GSa/sec sample rate and up to 500M record length, and 20X oversampling on a 500MHz signal providing unmatched signal resolution while still capturing a full 50ms. The core of the 7000 Series Oscilloscope is […]

Sinclair Appoints Two Tech Execs
Sinclair Broadcast is filling out its technical executive team, naming a new chief information officer and a deputy chief technology officer. Brian Bark, formerly of Hewlett Packard Enterprise, has been tapped as Sinclair’s first CIO, while Mike Kralec is joining the broadcast giant as VP of technical operations and deputy CTO. Bark is charged with […]
Modulated RF power amps for pre-compliance immunity testing
The TekBox TBMDA2/TBMDA3 Modulated Wideband Power Amplifiers are designed to create an inexpensive signal source for pre-compliance immunity testing of electronic PCBs and products. Driven by the tracking generator output of a spectrum analyzer, they provide the increased RF power outputs required by many test environments. With an input power range of up to -8 […]
Portable, 4-in-1 26.5 GHz calibration kits for T&M, field testing, antenna measurement and cable verification
A new line of 4-in-1 3.5-mm calibration kits for test and measurement, field testing, antenna measurement and cable verification applications consists of two models, both with a compact, lightweight, 4-in-1 design package. These short-open-load-through (SOLT) calibration kits have a 26.5-GHz calibration capability. They feature gold-plated 3.5-mm connectors and a handy lanyard. Plus, they are available […]
How to measure entropy
It was once widely taught that entropy is a measure of disorder. Educators increasingly feel that the concept of entropy as disorder can be confusing. So increasingly the “disorder” explanation is giving way to the idea that entropy describes energy spreading out or dispersing. The usual ways energy spreads out is when the system increases […]
Network-level channel emulator replicates field-testing conditions for MANET and mesh radios
The PROPSIM MANET Channel Emulation Solution secures end-to-end performance and interoperability of Mobile Ad-Hoc Networks (MANET) and mesh radio systems (a self-forming and self-healing reliable network that eliminates single points of failure) for tactical mission-critical wireless communications. Increased complexity and technological advancements, such as MIMO and beamforming in wireless military communication systems, has accelerated the […]
Low-cost alternative USB-to-GPIB controller
By languer, Electro-Tech-Online community member I was pressed to find a solution for a test automation need that needed to be simple and inexpensive. This led me to research for an inexpensive GPIB controller I could interface via USB and would allow me to control test equipment with. I planned to control the test equipment […]
Measuring earth’s magnetic field
Earth’s magnetic field is far stronger than that of Venus or Mars, and this single fact explains why life on earth is abundant while its nearest neighboring planets do not at present support life. Earth’s magnetic field extends from its outer core (where swirling molten iron produces a dynamo effect) up through the magnetosphere, extending […]
Understanding bandwidth concepts
Bandwidth has an array of meanings, depending on the context. Often, but not always, the term is applicable to a situation where one frequency is superimposed on, mixed with, or modulates a different frequency. A simple and fundamental example is amplitude modulation and its close relatives, frequency and phase modulation. When speaking of a broadcast […]
Bluetooth analyzer supports Wi-Fi 11ac and WPAN
The Bluetooth Vanguard now includes features that address the recent, rapid evolution of Bluetooth technology and related development complexities, including feature additions for Wi-Fi and WPAN coexistence analysis. Vanguard is an all-in-one, fully integrated system supporting wideband (all channels) capture and analysis of Bluetooth Classic (BR/EDR), Bluetooth Low Energy (LE), plus concurrent Wi-Fi 3×3 11ac, […]
