Multiplexer

Bitwise Systems (Goleta, CA) has announced their new Model QMUX16X2 Multiplexer designed to permit test and measuring equipment to connect to many signals. QMUX can measure two selected signals at the same time. The multiplexer features 16 inputs and 2 outputs and can be powered and controlled by a single, full-speed USB 2.0 compliant port. The multiplexer uses low-power reed relays and a USB controller in a DIN rail mount enclosure. It is suited to single or differential signals less than 10 MHz. Because the QuickMux uses mechanical reed relays, you can use it as a de-multiplexer as well as a multiplexer. The de-multiplexing capabilities of the QMUX16X2 permits two input channels and can be connected to any of the sixteen output channels on a standard 40-pin IDC header.

Switch-on-a-Chip ICs

Micrel (San Jose, CA) has launched the KSZ8895/8875/8864 series of low- power, highly integrated, 4/5-port Layer-2 switch-on-a-chip ICs. Leveraging Micrel’s latest green physical transceiver and switch technology, the product family achieves a 50 percent reduction in power consumption compared to the previous generation and features advanced power management and sophisticated Quality of Service (QoS) capabilities. The devices support a single 3.3V power supply with an internal 1.2V LDO, with options for 3.3V, 2.5V or 1.8V IO voltages. Further power savings are supported by advanced power management, including the device’s “Energy Detect Power Down” mode. This mode is activated when the cable is unplugged, and the “slow oscillator” mode is activated when the device is not in use.

Solid Edge® software ST3

Siemens PLM Software, Plano, TX, has released Solid Edge® software ST3, a hybrid 2D/3D design tool that features the company’s Synchronous Technology (ST), which accelerates product design, streamlines revisions, and improves importing and reusing of third-party CAD data. Synchronous-based models can be used directly with all assembly applications such as piping, frames, wiring, and assembly features. Synchronous-based part-to-part associativity lets users establish and alter design intent before, during, or after the assembly design process. Manufacturing dimensions on 2D drawings can be automatically transferred to the corresponding imported 3D model. Using its integrated simulation application, the software includes new torque and bearing loads, user-defined constraints, and new options for connecting assemblies such as bolt and sheet metal edge connectors. The program uses Microsoft SharePoint® 2010 to extend collaboration through project management, business analytics, and social media capabilities.

Product of the Month: Solar Simulation Measurement Tool

Oriel® (Stratford, CT) has announced a new uniformity measurement tool for measuring the uniformity of irradiance at the sample plane of solar simulators. The new PV tool is equipped with a single metal test platen, compatible with English/metric table mounts, and with all 3 test standards: IEC, ASTM and JIS. A detector head is provided with appropriate masking to the area defined by either the IEC or the JIS method, depending on the model. The system is designed to correctly place the test detector head in 17 predetermined positions as defined by JIS standard C8912, or in 64 equally-spaced positions, defined by IEC method 60904-9. The intuitive MUMS software package provides 2D and 3D surface plots to analyze XYZ positioning of the lamp to quickly attain optimal irradiance uniformity. Photonics West Booth #1301
