RadioInspector developers and partners don’t see all RF signals as the same or to be treated and analyzed the same way, but see them as unique individual events. Radio frequency signals hold a wealth of information that once accessed can take away much of the guess work and operator analysis time, while providing fast and accurate information, automatically identifying and classifying signals and providing the operator with precision information required while maximizing their sweep and analysis time. RF spectrum analysis has evolved to take advantage of signal wave form, header and I Q data and when combined with RadioInspector’s extensive sophisticated detection analysis and location features, offers a new generation of advanced capability for a wide variety of applications.
RadioInspector surpasses analogue spectral analysis by providing, for the first time, industry leading and TSCM sweep-enabling Signal Classification Analysis Recognition System (SCARS) and Digital Test (DTEST) technology. RadioInspector’s SCARS subroutine analyzes, while spectrum scanning, every signal event that breaks an operator determined signal amplitude threshold, automatically. Every detected signal is analyzed according to supported modulation type (including GSM, UMTS 3G, DECT, Bluetooth, Tetra, Apco25, DRM, DMR, IEEE 802.15.4 (ZigBee, ISA100.11a, WirelessHART, MiWi) and analogue TV (NTSC, PAL, SECAM with on screen demodulation), frequency, amplitude, detection count, time and header information. For detailed Wi-Fi signal and network analysis, a critical area where many systems fall short, the Wi-Fi Inspector hardware / software system was developed, further extending the signal classification analysis and recognition capability. Such technology allows each individual signal from supported communication standards to be identified and isolated, which is critical in noisy, crowded and dynamic real-wold RF environments as well as during remote monitoring. RadioInspector goes beyond common 2D spectral displays by providing a dynamic 3D waterfall display, where operators can easily observe individual signal artifacts ‘hidden’ between signal detection events, or be enhanced with the IQ analysis and constellation display, allowing for instant operator recognition of complex patterns that are undetectable with 2D waterfall displays.
Moreover the extensive analysis toolbox of RadioInspector allows the operator to ‘point and click’ on any detected signal and complete parametric detail about the signal is presented for review or export for reporting. Signals that are detected and can be demodulated are automatically recorded for post analysis by the built in digital audio analysis program, in frequency and time domain components. This program breaks down analogue components of signals using various DSP algorithms offering unique and innovative TSCM-specific audio signal analysis capability with audio files saved, sorted and stamped by date, time and frequency. Audio files can also be transferred over a network or the internet for off-site review.
In addition, the entire sweep, not just isolated or threshold events, is automatically saved with time and date stamps in an integrity protected database, which can be played back in its entirety in 2D and 3D views at operator selected speeds, for further analysis of TSCM critical events such as triggering signals for burst transmitters or harmonic identification. A search can be performed across previous saved sweep files by, date, time, frequency or span and detailed comparative differential analysis can be performed between any previously saved spectrum trace, or a spectrum reference trace can be created for comparative analysis from any portion of any previous saved sweep for unprecedented post analysis capability. For each GSM, Bluetooth, DECT, IEEE 802.15.4 (ZigBee, ISA100.11a, WirelessHART, MiWi) or Wi-Fi signal, RadioInspector will have identified the device, automatically compare it at against a list of authorized devices and flagged any suspect signals or associated events and the operator will already know if it is the boardroom printer or the CEO’s laptop etc. In the case of GSM and UMTS 3G, RadioInspector analysis allows for the identification of the service provider as well as cloned or rogue base stations which can be used for the interception of cellular phone traffic.
Signal detection is only the initial step in the Detect-Analyze-Respond cycle and as the complexity of an environment grows, it is this analysis of signals that will provide accurate, timely information in order to allow the TSCM operator to fulfill the cycle with precision. This is also particularly advantageous and even critical in a tactical sweep situation or for volatile environments where time is of the essence.
RadioInspector offers extreme flexibility, from software developed specifically for simpler scanning receivers such as those from Icom and AOR, to the most advanced flag ship spectrum analyzers from Rohde & Schwarz. In addition, RadioInspector is not simply offered in a 'one size fits all' package, but in a variety of configurations that can be customized for unique individual requirements including advanced TSCM operations and intelligence applications with detailed RF analysis, spectrum management, verification and regulatory compliance with intermodulation and interference analysis, true SIGINT capability with advanced high frequency signals analysis at resolutions as fine as 1 hertz while recording I and Q with quality digital filtering and audio recording, and even the ability (restricted) to control jamming equipment for selective jamming capability in support of government, military and law enforcement operations.
RadioInspector provides an advanced performance measurement subsystem for digital signal processing and precise frequency, field strength, occupied frequency bandwidth and full signal parameter estimation measurements, with the ability to input transmitter co-ordinates and antenna height data. Metrological measurement support integrates antenna calibration data when calculating measurement results and accounts for antenna gain/loss factors, intermediate transmission line losses and instrumental inaccuracies. Geographic information support provides integrated digital mapping with caching for offline use, geo-spatial co-ordinates for direction finding and drive by testing support for telecom infrastructure. A Standard or optional sophisticated, Advanced Authorized Frequency Database is provided to store all signal analysis measurements with associated spectrum, geographic and operational data in files that can be uploaded for further data collection or review at any time.
RadioInspector is also utilized as a sophisticated tool for advanced educational research and training applications at the university level and for post graduate studies.
