New Four-quadrant Voltage Drop Simulator for Automotive Testing
EM Test now offers a four-quadrant, bi-polar voltage drop simulator - the VDS 200Q Series. The amplifier can “source and sink current using a programmed voltage in both positive and negative polarities. The amplifier generates dips and drops, short interruptions and voltage variations to simulate a wide range of phenomena occurring on a vehicle wiring harness,” according to … [Read more...]
Log Video Amplifiers Perform Up to 18 GHz
Pasternack announces a new line of broadband logarithmic (log) video amplifiers that cover bandwidths from 0.5 GHz to 18 GHz. The amplifiers utilize GaAs semiconductor technology, which makes them ideal for use in measuring signals at high frequencies in high speed applications. “These log amplifiers can process up to 75 dB of dynamic range and have log linearity that ranges … [Read more...]
Maglev Hovering Train Breaks Speed Record
A seven car Maglev (magnetic levitation) Train in Central Japan broke its own speed record when tested near Mount Fuji this week. In 2003 the Maglev’s record was 268 mph and last week it reached 366 mph. On Tuesday the Maglev surpassed both previous records and reached 374 mph. The Maglev train hovers four inches above the tracks and is propelled by electrically-charged … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
FBI Pulled Security Expert from Flight for Alleged Hacking Concerns

Roberts tweeted referencing the plane’s communication systems suggesting he was going to use his laptop to force the plane’s emergency oxygen masks to deploy. The tweet read: “Find Myself on a 737/800, let’s see … [Read more...]
Power Inverter for Energy Grid Testing Bought by U.S. Dept. of Energy
The U.S Department of Energy’s National Renewable Energy Laboratory (NREL) has purchased its second AC/DC High Power Source from AMETEK Programmable Power. The AMETEK system is a high power inverter suited for Energy Grid Testing. If installed parallel with the previous AMETEK unit purchased in 2013, this new system can supply up to 2 MVA, which would make the system the … [Read more...]
