  1. emcware 6.0 FAQs 8/10/2021

    The AR RF/Microwave Instrumentation emcware 6.0 is a comprehensive EMC test software for radiated susceptibility, conducted immunity, radiated emissions, and conducted emissions. The emcware provides automated EMC testing and report generation for all types of EMC test laboratories.

  2. How Error Vector Magnitude (EVM) Measurement Improves Your System-Level Performance 8/9/2021

    Error vector magnitude (EVM) is a popular system-level performance metric that is defined in many communication standards, such as wireless local area networks (WLAN 802.11), mobile communications (4G LTE, 5G), and many more, as a compliance test. 

  3. Millimeter Wave Body Scanners Market: Past, Present, And Future 4/27/2021

    Full body scanners have become an important part of the security and threat detection toolkit around the world. This article discusses how system integrators of these full body scanners can be more confident in offering commercially viable solutions for this fast growing market.

  4. Contactless Fluid-Level Measurement Using A Reflectometer Chip 4/27/2021

    Fluid-level measurements can be accurately measured through the wall of a nonmetallic tank by placing an air-dielectric transmission line up against the side of the tank and sensing the RF impedance. This article provides an empirical design example that illustrates how a reflectometer device such as the Analog Devices ADL5920 can simplify the design.

  5. Accurate Gain/Phase Measurement At Radio Frequencies Up To 2.5 GHz 4/14/2021

    Electronic circuits fall into two broad categories—those that process and transform signals and those that measure signals. Circuits that measure RF signal strength, whose fundamental metric is power, are generally called detectors, but only a thermopile (bolometer) measures this quantity directly.

  6. XFdtd Simulation Of A Millimeter Wave, Wideband Dielectric Resonator Antenna 3/5/2021

    Dielectric resonator antennas (DRAs) are a good choice for millimeter wave applications due to their low loss and high efficiency. Designing the resonator for a fundamental mode can be complex due to the small size and sensitivity of the resonator to fabrication errors. In this example, a larger cylindrical dielectric resonator is simulated in XFdtd to show how the excitation of the higher order modes HEM113 and HEM115 can be used to produce wide bandwidth and good gain performance. 

  7. Leveraging Software-Defined Automated Test To Enable Digital Transformation In Aerospace And Defense 3/3/2021

    Aerospace and defense (A&D) companies are continuously looking for digital transformation initiatives to deliver sophisticated systems and capabilities in an increasingly complex business environment. A key enabler of digital transformation is the data generated by a system or device in operation, which can yield benefits such as reduced downtime, new service models, and valuable insights. With this digital transformation, the focus isn’t on testing more but on testing more intelligently. A sophisticated, software-centric approach to automated test and data management is essential for realizing the added value of test integration.
