 Two Sides of the DoD Coin: Budgets Slashed, UAV Market Soars
By Fred Ortiz, President
dB Control
As we embark on a new year, imminent cuts to the U.S. Department of Defense (DoD) budget are top of mind for those of us in the military electronics market. At a recent House Armed Services Committee hearing, the nation’s military chiefs cited a $600 billion defense cut as “catastrophic to the military” and having a “severe and irreversible impact.”

LightSquared:
The Show’s Over
…Or Should Be
By Barry Manz
There are a lot of very technically astute people at the Federal Communications Commission. Many have decades of experience at every level of RF and microwave technology. How then might LightSquared’s proposal for a satellite/terrestrial LTE network have ever gotten past its first hurdle? Even a cursory inspection of the plan, in which the company's network would operate extremely close to GPS frequencies at L-band, makes interference to GPS devices almost a certainty. Read More...

| RF Record and Playback System Has Instantaneous Bandwidth of DC to 6000 |
X-COM Systems has introduced the Wideband Acquisition Record and Playback (WARP) system that allows the entire frequency spectrum between DC and 6000 MHz to be instantaneously captured and recorded for long periods without loss of a single event.
When combined with X-COM’s Spectro-X signal analysis software, it allows the performance of electronic warfare, radar, and wireless communications, and satellite communications systems to be comprehensively evaluated.
The WARP system can capture directly from an antenna all activity from the lowest frequencies through C-band, which includes navigation, AM, FM, shortwave, and TV broadcasters, amateur radio, industrial, scientific, and medical (ISM) systems, cordless phones, aviation, government and military systems, all commercial wireless networks, WiFi, Bluetooth, GPS, as well as some radar and satellite communications systems. It can also accept the downconverted signals from higher frequencies, expanding its range through millimeter wavelengths used by satellite communications and other military systems.
The WARP system converts captured signals to the digital domain using a 12-Gsample/s analog-to-digital converter (ADC), and stores the data on solid-state media with capacity of up to 32 Tbytes that allows 44 min. of continuous signal capture. This data can then be analyzed with X-COM’s Spectro-X or other software to find signals of interest even when in the presence of much stronger signals or when interferers appear randomly and infrequently.
The system can reconvert the entire 6 GHz bandwidth or only the portion of interest to analog form so it can be used to stimulate a radar, EW, or communications system to evaluate its performance. X-COM’s WaveCAFE software can be used to create custom waveforms that can be incorporated into the data stream, and the signal pattern can be rearranged using X-COM’s RF Editor software, whose user interface is similar to that of professional audio or video editing software.
