World’s First Frequency Selectable RF Power Sensor with Coverage up to 70 GHz

first_imgAnritsu has introduced the Power Master MA24507A, an ultraportable, millimeter wave (mmWave) power analyzer that enables simple, numeric, frequency based measurement of RF power from 9 kHz to 70 GHz. It is the world’s first frequency selectable RF power analyzer.  The MA24507A leverages Anritsu’s patented Shockline technology, to address the growing number of test requirements in mmWave applications, including test of 802.11ad, Wireless HD, and E-band products, at every stage of the product lifecycle.As signal frequency increases, attenuation due to the air and cabling grows, which can make power measurements particularly difficult at mmWave frequencies. This analyzer’s ultraportable size overcomes this challenge by enabling users to place it directly at the signal source. It can even be used for on-wafer measurements. When system losses are unavoidable, it can make measurements as low as -90 dBm at 70 GHz, making it a superior alternative to large benchtop instruments, which can be difficult to manage in the field. This USB-powered device, measures approximately 6×3×1 (inches) and weighs less than 15 oz. – making it a little bigger than a smartphone. It is so small and light that it can easily be used to make measurements on antenna towers or with an extension pole to measure small cell signals from the ground.The Power Master MA24507A enables frequency selective power measurements, making it possible for users to differentiate intended signals from unintended signals. With spans from 1 kHz to full span over the entire frequency range, this device can zero in on a signal of interest in harsh environments, including those with unintended signals that can impact power readings. This enables measurements such as channel power and adjacent channel power to be made, while avoiding spurs and harmonics.Unlike many other power measurement instruments, no reference calibration is required. The power analyzer can stay connected to a test system constantly, eliminating the need to disconnect and reconnect it between test procedures. In tests where the extreme accuracy of a traditional power meter is not required, unintended signals may be present, or low-level power measurements are required, it is the ideal instrument. Anritsu has added features to PowerXpert™ to optimize the performance of the Power Master MA24507A. Included in the enhancements are a Power Hunter mode to easily identify the six highest CW amplitudes and their corresponding frequency, and a Channel Monitor mode so users can select up to six frequency channels and monitor their CW amplitude or channel power simultaneously. It can be controlled remotely via the USB interface or through their PowerXpert™ data analysis and control software.This mmWave power analyzer is the second instrument in the new class of ultraportable instruments from Anritsu, succeeding the Site Master™ S331P ultraportable cable and antenna analyzer introduced earlier this month.last_img read more

Can the Patriots go 16-0? Ranking the teams most likely to ruin New England’s shot at undefeated season

first_img (Getty Images) (Getty Images) The Patriots are looking like they have a shot to go 16-0 in the regular season for the second time in 12 years with Tom Brady and Bill Belichick. One can’t help but to think that way about New England as it outscores its opponents at an absurd rate — 223-48 heading into Week 8.The Patriots are averaging nearly 32 points per game and allowing fewer than 7 points per game, combining for a 25-point average margin of victory going into Sunday’s game against the Browns. New England was favored by 13 points against 2-4 Cleveland. 4. Houston TexansWe’re having flashbacks to those letterman jackets, but at least this Week 13 game is in Houston for two former Belichick right-hand men, coach Bill O’Brien and defensive coordinator Romeo Crennel.Deshaun Watson’s off-script playmaking can shake things up for the Patriots’ man coverage and make it tough on their pass rush, but the bigger problem here is the Texans’ pass defense against Brady, who can get the ball out quickly and spread it around to neutralize the rush of J.J. Watt and others. 2. Baltimore RavensJohn Harbaugh is only 3-7 head-to-head against Belichick, but he has had the Patriots’ number twice in the playoffs, and both times were with Joe Flacco. This time he will try his hand with a completely different style of quarterback in Lamar Jackson.The Ravens have not played the Patriots in two seasons, but you know what Belichick will do here: Have his defense focused on taking away Jackson’s running and forcing him to be effective throwing downfield against a strong, deep New England secondary. Jackson, like Watson, can give the Patriots problems with his improv, but the Ravens’ biggest shot here is running for ball control and stopping the run, forcing Brady to hang in there and deliver without mistakes against Marlon Humphrey, Earl Thomas and Marcus Peters. Still, Jackson will need to have the best game of his young career to finish the job. 1. Kansas City ChiefsDon’t remind Chiefs fans what could have been with Patrick Mahomes against the Patriots twice last season. They lost by a field goal in Foxborough in the regular season, and Mahomes didn’t even get a chance touch the ball in overtime in the AFC championship game loss at Arrowhead.All signs point to Mahomes and his key offensive teammates being fully healthy for this Week 14 game at Gillette Stadium. The Chiefs’ biggest weaknesses are stopping the run and covering the short-to-intermediate passing game, which does set up Brady for the ball-control game plan the Colts and Texans used to beat the Chiefs. To get over that hump, Kansas City needs a clean and spectacular game from Mahomes with no slow start and a strong finish.Make no mistake: The Patriots will be favored in all of these games and will feel good about going at least 4-1. Between Watson, Jackson, Mahomes, Dak Prescott and Carson Wentz, one athletic QB is bound to trip up New England. NFL POWER RANKINGS49ers, Packers inch up; Seahawks, Eagles fly higher; Bears, Bills slideExpect the big spreads in the defending champs’ favor to shrink between Weeks 9 and 14, however. So far the Patriots have faced zero playoff teams from last season, and the combined winning percentage of their opponents thus far in 2019 is .385.The schedule changes dramatically after the Browns game, as the Patriots will face five consecutive playoff teams from last season in six weeks around their Week 10 bye. Between the Ravens, Eagles, Cowboys, Texans and Chiefs, only one of those teams (Philadelphia) had a losing record (3-4) entering Week 8.Should the Patriots survive that November and early December slate unscathed, 16-0 will happen. In Week 15 they play at Cincinnati, and in Week 16 they host Buffalo. Even if they rest players at home in Week 17, they can beat the Dolphins.Here we rank those five opponents based on their chances to ruin the Patriots’ chances at a perfect season.center_img (Getty Images) (Getty Images) 3. Philadelphia EaglesThe Eagles’ record when they host the Patriots in Week 11 won’t matter. Nor will how dysfunctional they look now. Philadelphia’s players will have confidence against New England, and it would surprise no one if there’s more of a “Philly Special” feeling here with Doug Pederson pushing the right buttons in what might turn out to be a playoff run-saving game.Of course, then you remember they have an awful secondary with no consistent pass rush against Brady. 5. Dallas CowboysThe Patriots will host the Cowboys in Week 12, and in terms of an explosive and balanced offense, Dallas will be the most complete team New England will face.Jason Garrett, however, is the question mark. Can the coach be aggressive enough to outwit Belichick in a close, high-scoring game? Dallas has the talent to win, but one can’t be confident about it being the better executing and adjusting team.
