Milipol Paris 2019: Rohde & Schwarz presents new R&S PR200 portable monitoring receiver
At this year's MILIPOL in Paris, France, Rohde & Schwarz is showcasing the new R&S PR200 portable monitoring receiver. With a very wide frequency range from 8 kHz to 8 GHz, or even up to 18 GHz with the R&S HF907DC SHF handheld antenna with integrated downconverter, it is highly versatile. Thanks to its high linearity and effective preselection, the receiver is ideal for complex signal environments. To prevent overloading and adapt to any given situation, the receiver offers automatic gain control (AGC) to attenuate or amplify the input signal.

The R&S PR200 is an indispensable tool for regulatory authorities, mobile network operators, police forces, military units and other security organizations. They can use the portable receiver to search for and analyze known and unknown radio emissions and to localize signal sources. The receiver offers various display options, markers and other signal analysis tools.
Low weight was a design criterion in the development of the R&S PR200. At only 3.5 kg, the receiver features a long operating time of more than 3.5 hours, perfect for longer field operations. Thanks to extensive beta-user feedback, Rohde & Schwarz was able to position the R&S PR200 as THE go-to-tool.
The R&S PR200 offers wide-ranging recording capabilities for documentation purposes and subsequent signal analysis. The receiver can record and reproduce all measured values over a prolonged period, for example the amplitude, bearing, spectrum and demodulated audio information of a received signal. The receiver can take a snapshot of the I/Q signal with up to 60 million samples. Numerous options and extensions for the R&S PR200 support a wide range of applications. Another important feature is the additional DF function in combination with the R&S MobileLocator. Temporarily installed in a vehicle, this combination enables effective geolocation of all radio emissions even in difficult environments such as dense urban areas.
"The R&S PR200 features excellent RF characteristics combined with innovative signal processing and outstanding ease of use," says Jörg Pfitzner, Director of Product Management, Rohde & Schwarz Monitoring and Network Testing Division. "The R&S PR200 is the successor to the PR100, with similar appearance, size and weight. However, it is a completely new product and better than its predecessor in many regards, The R&S PR200 is the fourth generation of portable receivers from Rohde & Schwarz. It follows the R&S EB100, R&S EB200 and R&S PR100, which many customers use."
The R&S PR200 performs signal processing in two separate paths, each with up to 40 MHz realtime bandwidth, making it possible to simultaneously display the spectrum and analyze in the frequency domain, as well as to display the signal and demodulate in the time domain. The R&S PR200 reliably detects signals with a duration of 1.5 microseconds, so virtually no signal goes undetected.
