The R&S EM200 from Rohde & Schwarz is a Digital Compact Receiver that operates from 8 kHz to 8 GHz (can be extended up to 20 GHz). It is an optimized solution that detects, analyzes, and demodulates over a wide frequency range and optionally supports direction finding (DF) with compact Rohde & Schwarz DF antennas from 20 MHz to 6 GHz. This receiver can be operated as a single standalone station or integrated into various manned or unmanned platform solutions. It is equipped with a preselection stage that protects the receiver against overload due to high power input signals and an internal high-gain preamplifier stage that results in better receiver sensitivity. This system features parallel signal processing of spectral and demodulation paths for undisturbed signal monitoring and demodulation.
The R&S EM200 offers zero-span and gated spectrum functions that help users to analyze burst or pulsed signals, such as TETRA, GSM, and DECT, to examine individual channels of a transmission mode. It uses the polychrome function to differentiate separately superimposed pulsed signals and provides highly accurate Angle of Arrival (AoA) measurement results by connecting R&S CS-DF direction finding option and compact DF antennas.
The R&S EM200 provides easy networking and integration of systems with R&S RAMON or R&S ARGUS software, which ensures flexibility and adaptation to a variety of communication systems and data transmission bandwidths. It includes Windows-based, ready-to-use GUI virtual front panel control that offers fast and easy-to-use analysis via Ethernet. The system can connect to the R&S CS-IR trace recording and replay option that allows users to record monitoring traces with demodulated audio and geolocation, which can be replayed on the device or via the PC-based R&S EM200 GUI.
This compact test receiver requires a DC supply from 10 to 32 V and consumes 18 W of power. It can receive the power directly from a DC source, such as a vehicle battery, and provides the option to operate from both car and truck batteries. It is available in a 19” rack-mount enclosure and is ideal for signal interception systems, direction finding, spectrum monitoring, and radio-location applications.
