Radio receiver R&S®PR300

digitalGNSSmonitoring

Overview
The R&S®PR300 is a portable spectrum monitoring and single‑channel direction‑finding receiver for field spectrum operations, interference hunting, direction finding and geolocation. Base coverage is 8 kHz to 8 GHz; coverage can be extended to 20 GHz or 33 GHz with appropriate handheld antennas and downconverters. The receiver supports up to 125 MHz real‑time bandwidth (option) and a segmented scan architecture while maintaining handheld portability.

Key facts

• Operational range: 8 kHz–8 GHz (expandable to 20 GHz / 33 GHz with antenna downconverters)
• Real‑time bandwidth: up to 125 MHz (option R&S®PR300‑ZS)
• Panorama scan speed: >500 GHz/s
• Segmented spectrum scans: up to 4 non‑continuous segments
• CI‑based single‑channel DF with sub‑degree accuracy (with R&S®ADDx07)

Features & benefits

• Dual‑channel digital downconverter (DDC) and advanced DSP for simultaneous monitoring and uninterrupted demodulation.
• Parallel time‑ and frequency‑domain analysis (zero‑span) and time‑gated spectrum for TDD networks.
• Segmented scan to monitor non‑contiguous bands persistently.
• Multiple scan modes (PSCAN, HSCAN, FSCAN, MSCAN) with flexible trigger options for surveillance workflows.
• Recording and replay of spectrum traces, measurement results and audio; mapping and geotagging with triangulation functions.
• Software options for polychrome display, interference analysis, modulation and spectral measurements, GNSS timestamping and field strength measurement.
