Clear the path for 5G

Application card for mobile network operators

In the drive for maximum network throughput, hidden interference is the primary barrier to hitting your performance targets. With 125 MHz real-time bandwidth, the PR300 isolates elusive uplink noise and wideband distortions that degrade key signal-to-noise ratios. Pinpoint the source and ensure your network delivers its full rated capacity.

Uncover the hidden

Application card for intelligence agencies

In signal intelligence, comprehensive spectrum coverage is essential for a complete operational picture. The PR300’s 500 GHz/s scanning speed and time-gated direction finding allow you to capture and locate pulsed or low-probability-of-intercept (LPI) signals with high reliability. Gain immediate situational awareness and transform complex signal environments into clear, actionable data.

Complex monitoring tasks made efficient, precise and effortless with the PR300

Intercept agile transmissions

Leverage extreme scan speeds to capture fleeting signals.

In a volatile RF environment, signal duration is often the biggest challenge. The PR300 scans the spectrum at over 500 GHz/s, ensuring that frequency hoppers and short-burst emissions are detected the moment they appear. Gain a persistent view of the airwaves where standard receivers only see gaps.

Expose low-level emitters

Utilize superior dynamic range to see through the noise.

Don’t let high-power signals mask the data you need. With a 125 MHz real-time window and advanced internal preselection, the PR300 maintains laboratory-grade sensitivity in the field. This allows you to isolate weak, narrow-band signals even when they are hidden within crowded, high-traffic frequency bands.

Streamline signal geolocation

Convert raw bearings into location data with integrated tools.

Reduce the time between first detection and physical location. By combining real-time spectral analysis with optimized direction-finding workflows, the PR300 allows you to track and home in on signal sources while on the move. It turns a complex technical search into a fast, intuitive process for field operators.
