An Acquisition, A Free Microwave Symposium CD + Two, New Photovoltaic Array Simulators... All From Keysight Technologies

[SatNews] Keysight Technologies has been quite busy of late, with these three announcements among the company's most recent endeavors.

First, Keysight Technologies, Inc. (NYSE: KEYS) announced the firm had purchased Electroservices Enterprises Ltd., a U.K. company that specializes in test equipment service and solutions. Based in Telford, Electroservices provides a broad range of electrical, mechanical and physical calibration, repair and asset management services to a large number of defense, telecom and industrial customers.

The MicroApps program at the annual IEEE MTT-S International Microwave Symposium (IMS2015) that was held in Phoenix, Arizona had nearly 80 presentations covering the hottest topics in RF/uW. If you missed this important event, you can browse the table of contents to get a feel for current trends and then order an official IMS copy of the CD containing the presentation material, all compliments of Keysight Technologies.

Keysight has also provided links to the IEEE TV video recordings of the Keysight presentations, as well as arranged access to the course material presented at the inaugural RF Boot Camp (attendee value $100)!
Keysight Technologies, Inc. has also introduced two photovoltaic array simulators, the N8937APV and N8957APV, to help engineers develop, verify and maximize the performance of inverter maximum power point tracking algorithms and circuits.
Engineers need to ensure their solar inverters are capable of converting maximum power from the solar array to which they are connected. Developing and verifying the performance of inverter maximum power point tracking (MPPT) algorithms and circuits is challenging. MPPT algorithms are complex, and under-the-sun testing with a comprehensive set of temperature and irradiance conditions is difficult, expensive and time consuming.

“Small increments in power production have a dramatic effect on the profitability of solar power generation,” said Kari Fauber, general manager of Keysight’s Power and Energy Division. “Keysight’s new PV array simulators help engineers capture as much energy as possible from their inverters, to improve the economics of solar power generation.”
Engineers can use the new Keysight N8937APV and N8957APV photovoltaic array (PV) simulators in a laboratory or on a manufacturing line to simulate the output characteristics of a real-world photovoltaic array. The N8937/57APV PV array simulators are autoranging, single-output, programmable DC power sources that can quickly simulate I-V curve characteristics under different environmental conditions (temperature, irradiance, age, cell technology and more), enabling engineers to quickly and comprehensively test their inverters.
The N8937/57APV PV array simulators provide stable output power, built-in voltage and current measurements and autoranging output voltage and current from 500 to 1,500V and 10 to 30A. The autoranging capability makes the units more flexible than traditional rectangular-output power supplies because they expand the power curve to provide more voltage and current combinations.
In addition to using the N8937/57APV units to simulate PV arrays, engineers can use them for other test and measurement tasks. They provide 15-kW autoranging, programmable DC power for design verification and ATE applications that require just the right amount of performance at an affordable price. Engineers can easily configure multiple units in parallel to create a single power supply that offers more than 90 kW of power.
