Russia Seeks Invisible Air Defense Missiles
(June 16, 2016) Recently the Russian newspaper, Izvestia, reported that Russia wanted to hide its most sophisticated air defense missiles from U.S. spy satellites and spy planes by using containers that block the emission of electromagnetic pulses caused when operating electronic equipment. Citing an anonymous Ministry of Defense source, the Russian newspaper said the S-400 … [Read more...]
FCC Takes First Steps in Approving Wireless Medical Body Sensors
(June 21, 2016) U.S. healthcare facilities are getting closer to making Medical Body Area Networks (MBANs) a reality. A new website has been launched so hospitals can formally register their deployments of MBANs, which support wireless patient monitoring to transmit patient health data over a short range at low power levels. The U.S. is the first country to allocate spectrum … [Read more...]
FCC Wants Your Help Understanding Spectral Noise Floor
(June 15, 2016) The US Federal Communications Commission is trying to figure out exactly how much trouble is being caused by product emissions that effectively raise the overall noise floor over the frequency spectrum. Among the amateur radio and shortwave listener communities, the noise floor in the radio spectrum has obviously been rising as the number of devices in use that … [Read more...]
List of Common EMC Standards
You shouldn’t be surprised that Wikipedia has a comprehensive list of EMC standards. The list includes CISPR, IEC, ISO, European EN, FCC, and MIL-STD. There is also a link to the GR-1089-CORE EMC and product safety standards for network telecommunications equipment. A good link to bookmark. Click here. … [Read more...]
Power Sensors That Require No “Zero” or Calibration
Ladybug Technologies has manufactured a broad line of NIST traceable USB power sensors. The sensors are compatible with Windows XP, Win 7, Win 8; in 32 and 64 bit systems. LINUX-compatible sensors along with the only SPI & I2C sensor are also available. With their patented NoZero NoCal feature, it is not necessary to zero or calibrate before making measurements, even for … [Read more...]
Modular Spectrum Analyzer Announced at IMS
Berkeley Nucleonics recently announced and demonstrated their new Model RTSA7500 at IMS.

Ready-to-Use Semi-Rigid Test Probes Up to 6 GHz
Pasternack has introduced a new line of semi-rigid test probes designed to assist in testing microwave circuits. By soldering the outer conductor to the signal ground and the exposed center conductor to the trace carrying the signal of interest, sampling measurements with these probes can be made without having to create a separate subassembly circuit board or add a connector … [Read more...]
Feed Horn for Square Kilometer Array (SKA) Developed
(May, 2016) Chalmers University in Sweden has recently delivered a new feed horn design for the Square Kilometer Array radio telescope to eventually be built in South Africa and Australia. The new feed horn incorporates low noise technology based on nanotechnology that does not require special low-temperature cooling. The feed horn was designed to cover 350 to 1050 MHz, the … [Read more...]
