Isolation in Ultra Low Power Applications - Advances in isolation technology have reduced the power consumption of digital isolators by orders of magnitude, enabling safety and convenience in low-power applications. This webcast looks at several designs that take advantage of quiescent currents less than 1 µA per channel, including 4-20 mA field instrumentation, telecom interfaces referenced to negative 42-V rails, and battery operated devices.
Developing Multiple-Input Multiple-Output (MIMO) Systems with the AD9361 - As software defined radio (SDR) and multiple-input multiple-output (MIMO) become more prevalent, there is a need for more channel diversity. This webcast will detail how to use multiple AD9361 RF agile transceivers to create an N×N MIMO system, as well as explore the available tradeoffs in the design. The AD9361 is a fully integrated 2×2 MIMO transceiver. Its programmability and wideband capability make it ideal for a broad range of transceiver applications.
The Spectrum of Current Sensing: From DC to Light - Current measurement is an essential part of sensor interface, control, power management, and communications. The span of current sensing is from picoamperes to kiloamperes, and from dc to gigahertz (or light, when using photodiodes). We will cover high power and motor control, 4–20 mA industrial communications, energy monitoring, photodiodes, isolation, and developing precision current sources. We will also show on-line tools for circuit design.
Designing Wideband Front-ends for GSPS Converters - As high-speed A/D converter technology improves, so does the need to resolve very high intermediate frequencies (IF) accurately at high-speeds. This poses two challenges: the converter design itself, and the front-end design that couples the signal content to the converter. This webcast will define wideband passive networks and highlight important specifications for choosing a transformer or balun.
Digital Filter Design for Integrated RF Transceivers - This webcast introduces how MATLAB from MathWorks can be used for complicated filter design in wireless SDR systems and components. We will create a model of the Analog Devices AD9361 and AD9364 RF transceivers, as integrated on the AD-FMCOMMS2-EBZ and AD-FMCOMMS4-EBZ SDR development platforms. We will use that model to design a filter for the internal FIR filters using the generated coefficients in an example system design.
An Overview of Spectroscopy Instrumentation Techniques, Applications and Signal Chains - Spectroscopy techniques form the basis for almost all light-based measurements in laboratory and analytical instrumentation. This webcast will start with the basics, show the theory of operation, and describe some typical spectroscopy signal chains. Next, we'll explain the challenges of the primary photodiode path and finish with a discussion of the auxiliary measurements that need to be considered in the component selection and end system design.
Integrated Software-Defined Radio on Zynq®-7000 All Programmable SoC -- This course introduces wireless communication system design on the new Avnet Zynq®-7000 All Programmable SoC/AD9361 Software-Defined Radio Evaluation Kit featuring Analog Devices AD9361 single-chip RF agile transceiver. An IEEE 802.11 receiver example will demonstrate system-level simulation using MATLAB® and Simulink® modeling and code generation tools from MathWorks. Using the Xilinx Vivado® Design Suite, the system will be implemented for production showing the receiver detecting 802.11 beacon frames in a stand-alone system running UBUNTU desktop Linux on Xilinx Zynq AP SoC. Presentations will alternate with instructor-led demos to illustrate coding techniques within MathWorks and Xilinx development tools for high-speed digital signal processing.
Partitioning and Design for Precision Data Acquisition Systems -- Acquired analog signals can be manipulated and processed by either the analog or digital portions of a system, for example, through filtering, multiplexing, and gain control. The analog portions of a system can typically provide reasonably simple processing at fairly low cost, power, and overhead. Digital processing can provide far greater analysis power and can alter the nature of the analysis without changing hardware.
Model-Based Design For Motor Control Development -- This webcast gives an introduction to model-based design (MBD) and discusses how this design approach can speed up time-to-market and increase product quality. Topics covered will include SW tools, workflow, advanced testing and deployment of code to embedded targets; followed by a working example of how MBD can be used for motor control algorithm design, verification, and implementation.
Addressing System Integration Challenges with Isolated Industrial Interfaces -- Interfaces in industrial and instrumentation applications require isolation due to their harsh operating environments. The necessary isolation can be achieved with a digital isolator or an optocoupler. Integration of that isolation into the signal chain poses several challenges at the system level, including set-up, debug, and software related pitfalls.
Galvanic Isolation for Power Supply Applications -- This seminar discusses isolation and isolation technologies in terms of signal transmission methods and isolation materials, including optocouplers and digital isolators. Ii covers isolation usage, including current sensing, gate driver, and communication functions in ac-to-dc, motor control, hybrid electrical vehicles, PV, and other power supply applications.
Solving Isolation Challenges on Your Design -- This webinar reviews designs that require isolation to protect personnel and equipment from harsh electrical and mechanical environments. It discusses interface power requirements and approaches for achieving design objectives, and addresses performance tradeoffs and applicable safety certifications for interface components.
