No doubt one of the most revolutionary tools for the RF side of broadcasting was the advent of the network analyzer. Prior to its invention, measuring the response of an antenna system was more or ...

There are different ways, techniques, and equipment available to test antennas. As with any antenna system, regular testing as a component of an overall maintenance program will ensure maximum ...

To deliver the next generation of satellite applications, spacecraft are increasingly using phased arrays to combine multiple individual antenna elements to improve overall performance, increase gain, ...

The properties of an amplifier can be tested along the lines of the following sketch. Typically, this technique would be applied to an RF or microwave amplifier, but this technique's additional ...

MIMO will be key to 4G performance and functionality, but it demands new levels of over-the-air testing. A couple of years ago, independent European test laboratory Broadband-Testing put six of the ...

Last year, I provided a quick overview of ATSC USB tuners. This month, I'll provide a detailed comparison of three--DViCO's FusionHDTV5 USB Gold, the AutumnWave OnAirGT tuner and the Pinnacle HD Stick ...

In RF testing, an essential attribute of every RF signal generator is the maximum output power it can supply to a device under test (DUT) while maintaining spectral purity and level accuracy. The ...

WEST LAFAYETTE, IND. — A group of Purdue University professors has launched a start-up to create an auto-aiming wireless antenna system that reliably links users on vehicles and boats to the Internet.
