Rohde & Schwarz, a leading manufacturer of test & measurement, communications and broadcasting equipment, has developed an advanced portable receiver and directional antenna with integrated global positioning system (GPS) receiver and electronic compass for interference hunting and spectrum clearing of wireless infrastructure equipment. The R&S®PR100 Series portable receiver operates in a wide frequency range from 9kHz to 7.5GHz, and when combined with the R&S®HE300 Series GPS enabled directional antenna, is ideal for quickly detecting and locating the source of cellular band interference disrupting wireless infrastructure equipment. Featuring a compact and lightweight design, the reliable R&S®PR100 portable receiver provides 10MHz real-time IF spectrum and demodulation over a bandwidth ranging from 150Hz to 500kHz. The R&S®HE300 Series directional antenna's GPS capability provides advanced mapping and records bearing lines to more quickly and accurately locate the source of interference. In addition, the R&S®PR100 includes an audio tone indicator of signal strength to further help users identify the source of interference "In cellular systems, interference causes poor voice quality, dropped calls and low data throughput. The growth of the cellular telecommunication market has led to a crowded spectrum as the number of transmitters has significantly grown in recent years, and there are no signs of this market slowing down," said Bill Wangard, radiomonitoring and radiolocation product manager at Rohde and Schwarz. "When the R&S®PR100 Series portable receiver is used in conjunction with the R&S®HE300 Series directional antenna, users can more effectively hunt interference and clear the spectrum of unwanted cellular band interference." Common sources of cellular band interference include faulty modulated devices, harmonics, intermodulation, repeaters and jammers. The R&S®PR100 portable receiver scans a broad frequency spectrum, including GSM, UMTS, CDMA2000® and LTE networks to quickly detect and assist in eliminating the source of interference. The R&S®PR100 portable receiver features state-of-the-art digital signal processing that provides high receiver sensitivity to enable detection of extremely weak signals without loss in processing speed. The R&S®PR100 portable receiver and R&S®HE300 Series directional antenna's advanced functions and control concepts have been optimized for interference hunting and spectrum clearing of wireless infrastructure equipment. Further, the R&S®PR100 Series digitizes a sampled signal and applies Fast Fourier Transform (FFT) analysis to provide real-time spectrum analysis. The spectrum clearing equipment combines portability, ease of operation and direction finding capabilities to provide an ideal solution for tracking down cellular interference. The R&S®PR100 portable receiver features a built-in SD card for storage of measurements and provides LAN interface for remote control and data output.
