SDR- receiver USG-9000A

USG-9A   (9kHz - 9GHz)

USG-9A is an SDR mono block receiver with 1GBit/s LAN interface for stationary operations. With two USG-9A, it is possible to use a two-channel synchronous and asynchronous operation mode. Asynchronous mode allows you to automate the process of analyzing and recording detected signals without having to stop scanning the master complex.














USG-9M   (9kHz - 9GHz)

USG-9M is an SDR mono block receiver with integrated CPU mainboard incl. RadioInspector- software package for stationary, mobile and autonomous outdoor stand-alone operation.

USG-9M has a built-in battery package for independent operation up to 6 hours. USG-9M is ready for back pack operation and has a passive cooling system.

USG-9-Professional (9kHz - 9GHz)

USG-9-Professional is one of the most powerful mobile (customized) TSCM radio monitoring and signal analysis systems. It has a powerful laptop to ensure IQ analysis, an integrated 4 port antenna switch and an integrated battery for mobile applications.

  • Efficient, effective, 24x7 electromagnetic spectrum monitoring and signal of interest highspeed capture

  • Expert analysis of spectral and amplitude-frequency-time characteristics of received signals

  • Analysis of IQ data for signal classification and modulation analysis

  • Interfaces to a wide range of spectrum analyzes and COMINT/ SIGINT/ TSCM receivers with new instruments being constantly added, and customization available at nominal cost

  • Effective detection of clandestine or illicit signals using differences in panoramic display spectral masks, by displaying signal characteristics on a unique axis-variable 3 dimensional waterfall display, using geo-graphically diverse antennas for signal power difference detection, incorporating adjustable thresholds for signal detection, automatically providing an ‘exceedance list’ of signals that exceed defined thresholds

  • Comprehensive software tools for detection and recognition of low probability of intercept and complex clandestine signals which use sophisticated cloaking techniques: frequency division multiple access (FDMA), short burst transmissions, ultra- wideband and noise-like emissions, masking as authorized signals and narrow-band transmission (snuggling) in authorized spectrum

  • Saving of results (baseline, average, peak and difference spectrums and panoramic displays) for post- monitoring analysis and comparison to previous saved results;

  • Signals analysis of IQ Data for DECT, BlueTooth, GSM, UMTS, LTE, TETRA, APCO25, DMR, dPMR, NXDN, 802.15.4, DVB-T,, DVB-T2 Analog TV (PAL/ SECAM/ NTSC) DRM, Mobile Radio Trunking and hardware-based WiFi analysis

  • Wide range of program tools for radio monitoring results’ analysis

  • Automated tools for audio demodulation and recording

  • Remote control over TCP/IP network including transfer of demodulated audio signal in real time

  • Electromagnetic compatibility research, analysis of effectiveness of frequency spectrum use, searching for radio interference sources

  • Built-in tools for documentation of results.

Radio monitoring network with digital signal analysis and direction finding

The customer can create and operate a worldwide radio monitoring network of USG-9 receivers with a one or more monitoring & control center (MCC)/ subcenters. Status information’s of the receiver positions are forwarded over VPN channels to the MCC. The program I_Remote Check displays information’s about the detection of unauthorized signals, the operation of the receivers, their activation and deactivation, as well the exact position of the sensor in a facility plan or in geographic information system. Over VPN channels the MCC has access to all functions of the remote USG-9 receivers.
