Rohde & Schwarz Releases Portable Receiver for Radio Monitoring

(Product News, 28 Jan 2008)

Rohde & Schwarz has launched R&S PR100, a portable receiver designed for mobile radio monitoring. The equipment has a wide frequency range from 9kHz to 7.5GHz—making it suitable for diverse applications such as radio reconnaissance, locating interference sources, and frequency monitoring. Despite its compact size, the R&S PR100 offers high sensitivity and a scan speed of up to 2GHz per second.

Featuring real-time bandwidth of up to 10MHz and powerful digital signal processing capabilities, the R&S PR100 can intercept short-term signals such as those emitted by short-haul radio modules or military radios using frequency-hopping techniques. Because intercepted data is continuously buffered during scanning, no signals are lost during data processing. Stored activities can be displayed with a waterfall diagram. This means that even signals that are no longer being transmitted can be analyzed while the operator optimizes the receiver settings for the short-term signal being monitored.

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—allowing the operator to demodulate an audio signal, store it and—at the same time—intercept signals across the set IF bandwidth. As a result, no signals are lost during demodulation. Moreover, 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.
