The PL-P series of high performance DC power supplies from TTi offers a wide range of remote-control interfaces as standard. These include USB for simple PC connection, RS-232 for legacy applications and Ethernet for single PC or LAN based system applications. Designed to conform with LXI 1.2, the LAN interface includes a built-in web server which provides information, configuration and control via a web browser.
LXI (LAN extensions for Instrumentation) is the LAN-based successor to GPIB, combining the advantages of Ethernet with the simplicity and familiarity of GPIB. The LXI standard has already been adopted by many of the best known test and measurement companies as the natural successor to GPIB, and others are currently in the process of adopting it.
New PL-P series power supplies are linear regulated and offer very low output noise combined with excellent dynamic response. They are extremely compact, being only one-quarter rack width (107 mm) and 3U height (131 mm). Four units can therefore be fitted into a single rack width. High thermal efficiency enables an unusually high power density to be achieved for a linear power supply. Single-output models provide up to 90 W and dual-output units 180 W. Models are currently available for ranges of 0-15 V, 0-30 V and 0-60 V. The dual-output unit offers four modes of operation including a true parallel mode in which all 180 W is made available to one output, enabling it to supply double the current. The interfaces provide full control and readback with a setting resolution of 1 mV or 0.01 mA. Near-perfect load regulation can be achieved using the remote sense terminals which, like the output terminals, are fitted to both the front and the rear of the power supply. The command set is compatible with other TTi power supplies including the QL and original PL-P. An IVI driver provides support for common high-level applications such as National Instruments LabView or LabWindows, and HP/Agilent VEE.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
