Teledyne LeCroy WaveSurfer 4000HD High Performance 4-channel 12-bit Oscilloscopes

Posted on 8 November, 2019 by mixos

The fast Windows CE-based WaveSurfer 4000HD systems with solid-state drives make the world’s highest definition oscilloscopes even more economical, powerful and productive with an efficient and intuitive user interface.

Saelig Co. Inc. has introduced the Teledyne LeCroy WaveSurfer 4000HD range of high performance 4-channel digital oscilloscopes, with 12-bit vertical resolution based on Teledyne LeCroy’s HD4096 high definition technology. Four models are available with bandwidths from 200MHz up to 1GHz. This compact form-factor instrument features a large 12.1” multi-touch display for fast setup and operation. With a screen refresh rate of 175,000 wfm/sec, the WaveSurfer 4000HD samples at 5GSa/s for two-channel operation and 2.5GSa/s when sampling all four channels. With 12.5Mpts/ch (4-ch) and 25Mpts (2-ch) this makes it possible to maintain a high sampling rate over a long period of time, providing a better tool for finding rogue waveforms.

Teledyne LeCroy WaveSurfer 4000HD high definition 12-bit oscilloscopes with HD4096 technology have higher resolution than conventional 8-bit oscilloscopes (4096 vs. 256 vertical levels). 12-bit ADCs with high sample rates, combined with high signal-to-noise amplifiers, and a low noise system architecture to 1GHz enables the capture and display of signals with 16 times more resolution than other oscilloscopes. Waveforms captured and displayed are cleaner and crisper. Signal details that are often lost in the noise on other oscilloscopes are clearly visible and easy to distinguish with HD4096-based oscilloscopes. Additionally, the 4000HD’s 16-bit offset DAC permits ±10 V offset at 20 mV/div, ±4 V at 5 mV/div, and an amazing ±1.6 V offset at the highest sensitivity (1 mV/div). Such large applied offsets, combined with 12-bit resolution, makes it easy to acquire and view small signal variations (e.g. ripple, noise, transient interference) on DC or sensor signals. This also provides extended offset ranges for many of Teledyne LeCroy’s high voltage probes.

The WaveSurfer 4000HD’s MAUI with OneTouch interface for its 12.1” touch-screen display means that all common operations can be performed with a single touch. This puts all the power and capabilities of the oscilloscope at a fingerstroke. Drag, drop and flick gestures provide unsurpassed efficiency in oscilloscope operation. All the common Automotive and Embedded serial standards are supported with the WaveSurfer 4000HD’s extensive serial data tools, which provide high performance triggers and decodes. The scope series also features a 4-digit digital voltmeter and a 5-digit frequency counter, both of which work with any channel; measurements update even when system is not triggering. Teledyne LeCroy’s versatile LabNotebook feature stores all setups, waveforms, and screen images in a single LabNotebook file, to which may be added descriptive notes or screen image markups.

The optional 16-channel Logic Analysis package allows sophisticated mixed-signal capabilities to simultaneously view, measure, and analyze 4 analog and 16 digital channels. This enables triggering on protocol elements or specific data patterns using powerful conditional data triggering.

For frequency domain work, the optional built-in Spectrum Analyzer mode offers authentic “spectrum analyzer style” controls and can automatically identify and mark peak frequencies, fundamental frequencies, and harmonics, making frequency data easy to measure with reference and delta markers. A built-in Waveform Generator provides frequencies up to 25MHz in a wide variety of waveform types. Saved real-time oscilloscope waveforms or other signals can be uploaded to generate test or arbitrary waveforms.

Over 30 probes in 9 categories are available to suit a wide range of application areas. Power Rail Analysis is one such task in which the 12-bit resolution and low noise clearly shows small signal details on power rails, while the Spectrum Analyzer can help determine the root causes of high noise events.

The fast Windows CE based WaveSurfer 4000HD systems with solid-state drives make the world’s highest definition oscilloscopes even more powerful and productive with an efficient and intuitive user interface. They are ideal for debug and troubleshooting of power electronics designs, digital power management or power integrity analysis, automotive electronics systems, and deeply embedded or mechatronic designs. Bandwidth upgrades can be made to models at any time.

NVIDIA Jetson Xavier NX SoM Delivers up to 21 TOPS for AI Workloads at the Edge

Posted on 7 November, 2019 by mixos

NVIDIA has just announced Jetson Xavier NX system-on-module, with the company claiming it is the “world’s smallest, most powerful AI supercomputer for robotic and embedded computing devices at the edge” with a 70x45mm “Jetson Nano” form factor, and delivering either up to 14 TOPS at 10 Watts or 21 TOPS at 15 Watts.

The Jetson Xavier NX board features an Nvidia Volta GPU AI accelerator with 384 CUDA cores and 48 tensor cores, with two Nvidia deep learning accelerators. Its CPU is a 6-core Nvidia Carmel Arm 64-bit CPU.

The company expects the module to be used in small commercial robots, drones, intelligent high-resolution sensors for factory logistics and production lines, optical inspection, network video recorders, portable medical devices, and other industrial IoT systems.

Jetson Xavier NX specifications:

SoC – NVIDIA Xavier with 6-core NVIDIA Carmel ARM v8.2 64-bit CPU,
6MB L2 + 4MB L3 caches, and a 384-core NVIDIA Volta GPU with 48 Tensor Cores, 2x NVDLA deep learning accelerators delivering up to 21 TOPS at 15 Watts
System Memory – 8 GB 128-bit LPDDR4x @ 51.2GB/s

Like other Jetson boards and modules, Jetson Xavier NX runs Ubuntu-based Linux, is supported by NVIDIA JetPack software development kit, and CUDA-X AI libraries. The module supports all most common AI frameworks such as TensorFlow, PyTorch, MxNet, Caffe, and others.

In a world where AI chips are announced on what seems like a daily basis, I believe NVIDIA raised the bar with its Jetson Xavier NX — showing that exceptional performance at small size and low power, together with a consistent and powerful software architecture, is what matters in embedded edge computing.

There’s no Jetson Xavier NX development kit, but since the SoM is pin-compatible with Jetson Nano, so you should be able to reuse/upgrade existing carrier boards. In order to get started quickly, the company invites developers to begin application development using the Jetson AGX Xavier Developer Kit with a software patch emulating Jetson Xavier NX.

The Jetson Xavier NX, which is pin-compatible with Jetson Nano, will be available in March 2020.

NVIDIA Jetson Xavier NX SoM will be available in March for $399 to companies looking to create high-volume production edge systems, which reads like it won’t sell to individuals like makers or students. More details may be found in the product page.

HLK-7688A OpenWrt Development Board Comes with an Audio Jack

Posted on 7 November, 2019 by mixos

Another OpenWrt audio board based on the processor with HLK-7688A board featuring Hi-Link HLK-7688A module is launched.

HLK-7688A board specifications:

Wireless Module – HLK-7688A based on MediaTek MT7688 MIPS24KEc processor @ 580 MHz, and equipped with 32MB RAM, 128MB flash
Storage – MicroSD card slot
Connectivity
- 802.11 b/g/n WiFi 4 up to 150 Mbps with u.FL antenna connector
- 10/100M Ethernet
Audio – 3.5mm audio jack; 4-pin speaker header, WM8960 audio codec
USB – 2x Micro USB ports one USB 2.0 port and one for debugging & power
Expansion – 2x 26-pin headers with GPIO’s, SPI, UART, I2C, I2S, Ethernet, USB, GND, 3.3V…
Misc – 4x status LED’s for WiFi, LAN, USB, and WiFi; reset button, factory reset button (long press)
Power Supply – 5V via Micro USB port
Dimensions – Module: 32.8 x 18 mm; Board (est): 75 x 34 mm

The board is apparently sold as a video and/or audio streamer storing files in USB storage or MicroSD card to be played on your phone. Up to 8 phones are supported for photo sharing, and 3 phones for simultaneous video streaming.

One of the photos of the board shows it supports OpenWrt 3.10 with Linux 2.6.36 SDK. It’s probably a mistake, as when I tested the MediaTek LinkIt board two years ago, it ran Linux 3.18.21, OpenWrt Chaos Calmet 15.05+.

One buyer also mentions USB audio works just fine with Linkit firmware, and the latest version of OpenWrt can run on the board but without I2S nor I2C support. He later updated his comment with further details:

Openwrt driver support is left at v15 and even this version 15 is full of bugs. I2S is “mission impossible” andI could not get sound out of that board

If despite the software shortcomings, you’re still interested in the board, it can be purchased for $16.70 with WiFi antenna on Aliexpress, or alternatively you could get the module only for $10 shipped from the same link.

As a side note, while looking for other HLK-7688A boards on Aliexpress, I came across one with 5 Ethernet ports since the processor supports this.

644/1284 Narrow – The smallest Atmega644/1284-based board

Posted on 7 November, 20193 July, 2020 by mixos

644 Narrow and 1284 Narrow are the simplest and perfect upgrade option for all your small footprint Arduino projects. The Narrow board gives you 2 to 8 times more flash and RAM resources as compared to a Uno/Nano, plus total compatibility.

A large amount of effective Flash and RAM. Effective because the code generated on 8 bits MCU is much smaller than on 32 bits MCUs. Hence you can load a bigger program on these 64k/128K MCU than on a 256k 32 bits MCU! Atmega644/1284 also have EEPROM that adds to the total storage capabilities.
A small footprint. Narrow boards are approximately 1/5 the of the surface of a Mega2560 board, and half its current consumption.
Perfect Arduino compatibility. Ten more digital I/Os and one more UART port.
Best choice for your 5 volts projects.

The project is going soon to launch on CrowdSuppy.com

UPDATE 03/07/2020: The project is now live on Crowdsupply.com

Energy-efficient EnOcean Wireless Transceiver Module

Posted on 6 November, 20196 November, 2019 by mixos

The compact wireless transceiver module TCM 515 offers reduced power consumption, smaller size and a lower purchase price compared to the previous generation TCM 310.

Now available at Rutronik UK, the module is suitable for systems such as transceiver gateways, actuators and controllers that communicate based on the EnOcean radio standard in the sub-GHz band. Thanks to a higher processor performance, all security features – encryption, decryption and authentication – can be performed directly in the module. This enables a secure end-to-end communication without external components.

The TCM 515 module, pre-certified according to international radio standards, receives radio telegrams either via wire antenna, PCB antenna or an external 50 Ohm antenna. It can filter, decrypt and authenticate these telegrams before forwarding them to an externally-connected host processor or host PC via a serial UART-interface (Universal Asynchronous Receiver Transmitter). Thanks to the integrated security processing no additional components are required for encryption.

The serial interface operates according to the EnOcean ESP3 standard with the option to use higher interface speeds (TURBO mode) to reduce latencies. ESP3 messages received from the external host will be encrypted and authenticated as required before they are transmitted as EnOcean radio telegrams.

The wireless transceiver module TCM 515 / S3003-K515 supports the radio frequency 868MHz for Europe while the TCM 515U / S3053-K515 supports 902MHz for North America.
