Spectrum offers driver support for the Nvidia Clara AGX

Fri, Apr 29, 2022

Driver support for the Nvidia Clara AGX universal computing architecture means that developers can select one of 64 digitisers, arbitrary waveform generators and digital I/O cards from Spectrum Instrumentation for use in artificial intelligence (AI) medical instruments.

For example, the digitiser cards can be used to acquire signals in the DC to GHz frequency ranges by sampling them at rates from 5Msamples per second up to a maximum of 5Gsamples per second.

The arbitrary waveform generator, which outputs samples at 40Msamples per second up to 1.25Gsamples per second, can be used to produce signals with almost any wave shape and frequency content, from DC to 400MHz, said Spectrum.

Individual analogue cards offer one, two-, four- or eight-channel capability. Digital I/O cards and digital data acquisition cards allow the acquisition of digital data at rates up to 720Msamples per second and can generate digital patterns at up to 125Msamples per second. There are different interface options for TTL and LVDS available.

Nvidia’s Clara AGX developer kit can be used to develop software-defined, AI-enabled, real time, point-of-care medical devices. It delivers real-time streaming connectivity and AI inference via the Jetson AGX Xavier, Arm-based SoC, the RTX 6000 GPU and the ConnectX SmartNIC with 100GbE connectivity. The kit also includes full-stack GPU-accelerated libraries, software development kits and reference applications.

Adding a Spectrum card to the Clara system allows sensor signals to be acquired, generated, stored and processed, explained the company. Data can be streamed between the cards, the processor and the GPU. The GPU’s high speed parallel processing capabilities ensure that large volumes of data can be acquired and generated by the Spectrum products. Spectrum already offers SCAPP (Spectrum’s CUDA Access for Parallel Processing) for GPU-based data processing.

The Nvidia Clara is already used in biomedical research programmes and medical devices, around imaging, genomics, patient monitoring and drug discovery.

The M2p- and M4i-series cards all carry a five-year product warranty, with free software and firmware updates. There is customer support directly from the engineering team for the lifetime of the product.

Fri, Apr 29, 2022

Long reach Ethernet connectivity is added to controllers, sensors and actuators in smart building networks, using the ADIN2111 10Base-T1L Ethernet device introduced by Analog Devices (ADI).

The ADIN2111 is designed for building automation networks. Digital, connected automation equipment enables holistic building management, said ADI, from heating ventilation and air conditioning to occupancy comfort.

Adding long reach Ethernet connectivity to controllers, sensors, and actuators delivers building management systems insights for more efficient and sustainable building management, said the company. The ADIN2111 is suitable for use within small, power-constrained edge devices. With a power consumption of 80mW, it provides up to 50 per cent power consumption savings. The 48-lead LFCSP, measuring 7.0 x 7.0mm is claimed to save up to 75 per cent in PCB real estate when compared to discrete implementations.

It has an SPI (serial peripheral interface) host interface which removes the need for a microcontroller with integrated MAC interface, advised ADI. The advanced packet filtering offloads the burden of priority traffic management from the processor via the 16 MAC addresses look up table, added the company.

The ADIN2111 is designed for daisy chaining data in line and ring networks using existing deployed single twisted pair cabling infrastructure within buildings. This contributes to a reduction in retrofitting costs, added ADI.

The device includes enhanced diagnostic features to reduce commissioning, installation and system downtime by troubleshooting problems quickly using the real time information on link quality and fault location. It is compliant to the IEEE 802.3cg standard to enable Ethernet connectivity over 1.7km of cabling, in addition to support for ring redundancy and soft real time protocols like Modbus/TCP, BACnet/IP and KNX.

The ADIN2111 is in full production now and is available in a 7.0 x 7.0mm package.

Analog Devices offers a suite of analogue and mixed signal, power management, radio frequency (RF) and digital and sensor technologies for customers worldwide operating in the industrial, communications, automotive, and consumer markets.

Vector signal generator addresses wideband multi-channel mmWave applications

Thu, Apr 28, 2022

The M9484C VXG four-channel vector signal generator offers up to 54GHz frequency and up to 5GHz RF bandwidth and low phase noise in a single instrument.

It also has real-time capabilities to support wireless applications and a V3080A vector signal generator frequency extender which expands the frequency range up to 110GHz.

Testing 5G mobile communications, 6G research, satellite communications and radar applications requires signal generation equipment capable of creating millimeter-wave (mmWave) signals at high bandwidths. These applications also adopt multi-antenna techniques, such as spatial diversity, spatial multiplexing and beamforming for multi-antenna test applications such as MIMO and beamforming with precise phase coherence and timing synchronisation.

The M9484C VXG signal generator enables customers to reduce test system setup complexity and achieve accurate and repeatable multi-channel measurements in a single instrument, said Keysight.

The instrument covers frequency ranges from 9kHz to 54GHz and up to 110 GHz with the frequency extender.

A fully integrated, calibrated and synchronised signal generator delivers low phase noise and minimises measurement uncertainty, said Keysight and the signal generator overcomes the excessive path loss experienced at mmW frequencies with low error vector magnitude (EVM) and distortion at high output power.

Direct digital synthesis (DDS) technology delivers RF performance which can characterise devices under test (DUTs).

Real-time signal processing and comprehensive signal creation enables complex test scenarios and simplifies test complexity for receiver and performance tests.

The M9484C VXG also supports MIMO real-time fading for all 3GPP 5G new radio (NR) required base station conformance tests with PathWave Signal Generation software.

In addition to streamlining complex receiver test scenarios with eight virtual signal emulation per RF channel, for up to 32 signals, the pre-defined compliance test set ups, auto-configuring signal analysis are designed to simplify the test workflow.

Keysight Technologies delivers design and validation products, software-driven insights and analytics that bring tomorrow’s technology products to market faster across the development lifecycle, in design simulation, prototype validation, automated software testing, manufacturing analysis, and network performance optimisation and visibility in enterprise, service provider and cloud environments.
