Keysight Adds Real-Time Spectrum Analysis to its MXE EMI Receivers

first_imgKeysight Technologies has announced the availability of real-time spectrum analysis (RTSA) as an option for its standards-compliant MXE EMI receiver. Adding RTSA to an MXE enables test labs to observe and diagnose transient and wideband emissions during electromagnetic compatibility (EMC) compliance and precompliance testing.With RTSA, engineers can more easily see and understand high-speed transient signals that are difficult to capture with traditional spectrum or signal analyzers. This is especially useful in applications such as radar, automotive and wireless communications that often experience fast-moving, short-duration emissions.In RTSA mode, the MXE can provide real-time analysis bandwidth up to 85 MHz below 3.6 GHz and up to 40 MHz above 3.6 GHz, ensuring image-free, over-the-air diagnostics that enable faster, easier analysis of emissions. RTSA offers 100 percent probability of capture for signals with durations greater than 3.7 µs when viewing with an 85 MHz span.The Keysight MXE EMI receiver now offers real-time signal analysis (RTSA) for diagnostics of high-speed transient signals that are difficult to capture.Frequency mask trigger (FMT) capability is also included with RTSA, allowing users to confidently trigger on signals with durations as short as 17.4 µs. In addition, time-qualified triggering capability further enhances FMT by simplifying the task of finding pulse outliers or triggering on specific communications bursts.RTSA is an upgradeable option on new and existing MXE EMI receivers as well as UXA, PXA and MXA X-Series signal analyzers. Adding RTSA enables engineers to see, capture and understand the most elusive signals, known or unknown. For deeper analysis, engineers can combine a real-time X-Series signal analyzer with Keysight 89600 VSA software to create a solution that enables thorough characterization of today’s most complex signals.U.S. Pricing and AvailabilityThe RTSA option for MXE (N9038A-RT1) is available for order and has a list price of $22,500.last_img read more

Wearable Interactive Tattoos Facilitate Contactless Payments

first_imgPlastic cards, cash, and even smartphones could one day be replaced with a new type of payment method that is a bit harder to misplace: a tattoo-like sticker.MC10’s Wearable Interactive Stamp Platform (WiSP) is an ultra-thin sticker that resembles a tattoo. What makes it so extraordinary is that it contains near field communication (NFC) technology enabling it to connect to an NFC-capable device such as a smartphone or a dedicated reader.This type of technology could inherently be more secure; it isn’t a loose physical object you could easily misplace. For patients in hospitals, it could replace the often bulky wrist bands medical workers use to identify and track patients.Removing the WiSP is easy, but doing so tears it so that the information it contains becomes unreadable and any data stored within virtually useless to any would-be thief. As a payment method, the WiSP could be used to store your credit card information and swiped over a contactless reader, freeing the wearer’s hands – and pockets.MC10’s technology is already being put to use by L’Oréal to research skin exposure to UV rays and the company is seeking other businesses to partner with to take the technology even further.last_img read more

Thompson’s late heroics blazes Warriors past Grizzlies, 106-94

first_img[av_textblock size=” font_color=” color=”]OAKLAND – The Warriors took a big step forward in securing a home-court advantage in the playoffs with yet another offensive surge in the second half, keyed by a stifling defense.More importantly, Golden State put some more distance between itself and a possible first-round matchup against Memphis – one of only two teams to have beaten coach Steve Kerr’s squad more than once this season.Klay Thompson scored 21 of his 31 points in the second half and the Warriors pulled away in the fourth quarter to beat the Grizzlies, 106-94, on Sunday for their seventh straight win.”We just picked up our intensity,” Kerr said. ”Most of the second half, I thought our defense was much better. That fueled our offense a little bit. When we can get stops and get out and run and hit a couple of 3-pointers, that really gives our team a good charge.”Stephen Curry added 21 points and 11 assists, Andre Iguodala scored 20 and Draymond Green had nine points and seven rebounds as the Warriors (59-14) extended their lead to 2 1/2 games over the San Antonio Spurs in the race for the top spot in the West.The win did more than keep Golden State in front of San Antonio. It also kicked off a stretch of five games in eight days when the Warriors will face playoff contenders Houston (twice), San Antonio and Washington.”At this point in the season and the playoff teams that we have coming up, it gets you into that focus mode,” Curry said. ”It’s a good warmup for us to understand how important each game is, each possession is, and not look ahead. That’s playoff mentality.” ”We did a great job of running them off the 3-point line, helping out on Z-Bo (Randolph) in the post and flying around,” Thompson said.
