R&S®PR300 - Elevated spectrum monitoring for intelligence agencies

Your task

The proliferation of 5G, IoT and high-speed data applications has created a complex electromagnetic environment. For intelligence operations, this density makes it increasingly difficult to isolate signals of interest from the background noise of modern wideband communications. Critical signals are often short-lived or intentionally hidden within complex frequency swaths. In urban areas, the use of beamforming and massive MIMO further complicates the task of locating and identifying unauthorized or person-to-person communications. To maintain situational awareness, operational teams require the capability to detect and record these transmissions in real time, even when they are embedded in highly congested environments. You need to identify and analyze signals of interest across a wide frequency range while maintaining a low physical profile in the field. As communications technologies evolve, teams must be able to capture high-bandwidth data and perform immediate on-site analysis without relying on stationary laboratory equipment. Your objective is to provide field personnel with a mobile solution that ensures no critical transmission goes undetected or unrecorded.

Speed as a decisive factor

In time-critical scenarios, the system measures with an extremely high scanning speed of more than 500 GHz/s. This enables rapid spectrum clearance and efficient interference hunting in commercial 5G and LTE networks. The combination of high speed and technical accuracy ensures that users maintain a complete overview even during major events or while managing the most complex monitoring tasks.

Advanced RF performance and real-time analysis

The technological core of the R&S®PR300 is its 125 MHz real-time bandwidth. Supported by high-performance preselection, this ensures the seamless detection of the most complex wideband signals. The hardware excels with advanced features such as segmented panorama scans, embedded spectrum analysis functions and the ability to perform direction finding on time-gated signals.

Versatility in application

The R&S®PR300 supports a range of applications in fieldbased signal acquisition and analysis. It is designed for tasks such as spectrum monitoring, the detection of low probability of intercept (LPI) signals and the identification of unauthorized transmissions. With its time-domain analysis and I/Q recording capabilities, the receiver provides the raw data necessary for detailed post-mission analysis and signal classification, making it a reliable tool for diverse tactical operations.

Robustness and minimal maintenance
