Portable receiver for mobile radio monitoring launched

A new 3.5 kg portable receiver should make radio monitoring, incuding the tracking of illegal transmitters such as bugs, much easier

Rohde & Schwarz has introduced a new portable receiver for mobile radio monitoring. The R&S PR100 has a frequency range from 9kHz to 7.5GHz and can be used for radio reconnaissance, locating interference sources and frequency monitoring. Scan speed is up to 2.0GHz per second. The likely market is regulatory authorities, industry and armed forces.

The receiver can intercept short-term signals emitted by short-haul radio modules or military radios using frequency-hopping techniques. The intercepted data is continuously buffered during scanning, so that signals are not lost during data processing. Stored activities are displayed with a waterfall diagram.

The IF bandwidth of the R&S PR100 ranges between 10kHz and the 10MHz maximum visible real-time bandwidth. As a result, the receiver can be adapted to handle a variety of radio services such as air traffic control, shortwave, TETRA or UMTS. IF bandwidth can be selected independent of demodulation bandwidth. An operator can demodulate an audio signal, store it and ̵1; at the same time ̵1; intercept signals across the set IF bandwidth.

The differential spectrum display lets the operator compare stored frequency occupancies with signal activities currently being received. Any differences will be shown in the differential spectrum. This feature makes it possible to track illegal transmitters such as bugs without a major analysis effort.

The R&S PR100 processes both analog and digital signals. Digitally modulated radio signals such as TETRA, Packet Radio, or Pactor III can be demodulated in the baseband with an I/Q demodulation bandwidth of up to 500kHz and stored on an SD card in real-time. After completing a mission, data stored on the SD card can be transferred to an external PC via USB or LAN or the SD card itself. Recorded digital emissions such as Pactor III can then be analysed offline.

The portable receiver may also be deployed for unmanned operation because it can be fully remote-controlled via its LAN interface ̵1; as part of a stationary radio monitoring system, for example. Moreover, the R&S PR100 can perform automatic functional tests quickly and easily ̵1; on radio equipment, for example ̵1; because the receiver settings for a variety of signal and frequency scenarios can be directly stored on the SD card and recalled as needed.

Airport operators, police, government authorities, and other security organisations can perform continuous checks to ensure the proper functioning of their radio systems.

Weight is 3.5kg and operating time approximately four hours.
