Liquid cooling sub-system dissipates board-level heat Product News 1/25/2005 Post a comment Here's news of a cooling sub-system that uses liquid cooling to efficiently and cost-effectively dissipate heat from embedded systems. The ruggedized unit---suitable for MIL/aero applications---combines a pump, heat exchanger, and control systems in a single enclosure. It's capable of dissipating a kilowatt.
Nifty mini data-acq pods talk USB Product News 1/21/2005 Post a comment National Instruments is kicking up portable USB-based data-acq and control a notch or two. NI's latest data-acq pods dish up eight channels of 12-bit or 14-bit analog input capability, and pack two analog outputs, 12 digital I/O lines, and a counter. Both draw operating power from the USB bus. eeProoductCenter Senior Tech Editor Alex Mendelsohn offers his notes, along with NI's.
MIPS, Q-Logic report strong quarters News & Analysis 1/19/2005 Post a comment MIPS Technologies Inc. and QLogic Corp. reported year-over-year gains in earnings and sales for their December quarters, as demand for the products and services of both companies continue to remain robust.
Mini USB board bridges to I2C bus Product News 1/19/2005 Post a comment These days, USB impacts everything from memory sticks to test-and-measurement and data-acq. Here's a new product from Saelig that can help you use and embed USB in your next instrumentation and/or data acquisition and control project. The mini interface board comprises a straightforward way to get a drop-in 12-Mbits/s USB interface with your host PC, providing a 5-pin connector for 90-kbit/s I2C serial interfacing.
Data Translation expands its USB data-acq module family Product News 1/19/2005 Post a comment A growing family of USB-connected data-acq boards and boxes at Data Translation now includes screw-terminal and embedded versions. Both provide 32 analog-input channels running at an aggregate throughput rate of 500-kHz, using USB v2.0 at 480-Mbits/s.
Satisfying the need for an inexpensive non-isolated PoE dual power supply News & Analysis 1/19/2005 Post a comment Power Source Equipment like Hubs with Power over Ethernet capability are emerging and any of these applications are very price sensitive. To serve the powered devices with a supply voltage of 3.3V or 5V, it is necessary to have a buck converter that scales down the available input voltage from the power source equipment. A Texas Instruments engineer details how you can develop one.
LXI-standard thermocouple conditioner is an industry-first Product News 1/12/2005 Post a comment eeProductCenter Senior Tech Editor Alex Mendelsohn reviews an industry-first: an LXI-compliant thermocouple conditioner from VXI Technology. Its new rack-mounted box is a 48-channel instrument based upon the emerging LXI standard. With a built-in Web page, this scalable instrument can also communicate across your Ethernet network.
Characterizing PC audio devices -- some challenges and their solutions Design How-To 1/5/2005 6 comments The ubiquitous PC is no longer just a sophisticated word processor or email tool; it's migrating into a personal jukebox or even the entertainment center of the home. But what level of audio performance do today's PC audio systems actually deliver? While 24-bit converters provide excellent THD+N specs, the PC environment is noisy and even the interconnections can degrade the overall system performance. An Audio Precision engineer offers insights into the measurements manufacturers can make to en
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
