and Post Signal Detection Data Recording, Storage and Analysis
RadioInspector has increased its data recording, storage and analysis
capability. For each signal that exceeds and operator determined threshold,
including the unique Dynamic Threshold, operators can now select the number of
spectrum scans both prior to and after each signal detection event with a predetermined bandwidth, for recording and storage in separate files.
Each signal breaking a predetermined threshold is added to the list of detected signals with spectrum graph for review and operators can select automatic audio recording, signal classification and recognition testing and recently announced separate IQ data recording. Now, data for each individual signal detection, including operator selected pre and post event data, is saved as a separate scan file and can be analyzed with the same tools as full recorded spectrum sweeps with the RadioInspector RP post processing program. This includes file playback at user selected speeds (forward or reverse) with 2D and 3D waterfall spectrograms.
Each sweep measurement within the recorded signal file is displayed with the date/time, maximum db level and (if a GPS receiver was used during data collection) the longitude, latitude, altitude, speed (if mobile) and antenna compass information. The signal time-level trace can be displayed and played back, and full parameter measurements can be performed on current, maximum or average values including field strength, occupied frequency bandwidth and frequency of employment. Harmonic and interpolation analysis can also be performed to identify sources of interference.
Once a signal file has been recorded it can be displayed. When selecting the file, operators can choose to center the signal frequency with selected bandwidth in a new window for monitoring and further data collection, or immediately open the file with RadioInspector RP to begin post analysis. As with full spectrum sweeps, post analysis measurement results for each detected signal file can be saved into RadioInspector’s database and any portion of the file can be isolated and re-saved as a new file.
This new ability to save and store separate individual detected signal files with pre detection and post detection data provides even greater, advanced capability for all spectrum analysis applications.
RadioInspector software provides the ability to connect to
multiple receivers simultaneously through a single application. From the
measuring setup window, operators can connect additional receivers from the more than 150 supported instruments, by
direct connection, remote connection or a combination of both.
Receivers are monitored in separate windows with
all data streamed directly to the connected computer via
RadioInspector’s proprietary ‘I_Master Device’ program. Data from each receiver
is saved in separate, individual files to the RadioInspector database for
recall and post analysis.
* Files can be located for post analysis with RadioInspector RP using individual file names or with search filters including date and time, frequency or frequency band and receiver model.
Multiple connections provide the ability to task different receivers to monitor separate frequency bands, perform discrete frequency monitoring and analysis, RF performance parameter measurements or IQ analysis. Receiver data collection points can form 'RadioInspector Networks' locally or internationally and be monitored individually, in groups or all at the same time.
The number of receivers that can be effectively monitored at one time with a single computer will be dependent on available memory and processing resources. However, RadioInspector has been designed with no limits as to the number of receiver connections that can be made. This provides government and law enforcement organizations with the flexibility to use the amount of resources they choose for any level of monitoring complexity.
RadioInspector’s stand-alone I_Remote Check program further
compliments this capability by providing the option to monitor any number of
receivers within the same network simultaneously for signals that break
operator determined thresholds. In this case data is recorded and stored on each local computer. When using the I_Remote check program, the location of each receiver can be displayed on an uploaded floor plan
or geographic map with live, active status icons, audible alarms and individually viewable detected signal
RadioInspector: Automatic IQ Data Recording and Storage
RadioInspector now provides the ability to automatically
record and store IQ data for signals that break an operator determined
threshold, including RadioInspector’s unique, first of its kind dynamic
threshold. Operators can enter a sampling rate (kHz) and
recording length for each detected signal. Stored IQ data files can then be loaded
at any time for post processing and analysis or export as required.
This latest feature adds to RadioInspector’s unique,
multi layered IQ capability which includes the Signal Classification Analysis
and Recognition sub-system (SCARS) and DTEST (Digital Test) program providing advanced, in depth
analysis of streaming IQ data for supported critical digital communication
RadioInspector’s RF analysis and performance measurement
sub-system provides live IQ digital processing for up to 8MHz of selected bandwidth with
phase and amplitude analysis, filtering and decimation and constellation diagram.
IQ data can also be manually recorded during live spectrum scanning
with an operator selected recording length for any chosen signal or bandwidth
(up to the IF bandwidth of the receiver). When a wide bandwidth is recorded,
individual signals or any portion of the recorded IQ data can be isolated and saved
as a new file.
Recorded IQ data files are processed by the sophisticated
stand-alone IQ process program, which was recently enhanced to provide the
ability to process IQ data files of any size and includes a new scatter plot
The ongoing development of RadioInspector’s class leading IQ data recording and analysis provides operators with the ability to utilize current advanced receiver capability but also upcoming improved receiver hardware and computer performance as it is introduced into the market space.

‘Tablet Mode’ Option.
RadioInspector now includes a new tablet mode setting for use with the RadioInspector RT/RC main scanning and analysis programs as well as the RadioInspector RP post processing and analysis program. The setting enlarges the GUI control buttons for the Geographic Information Support system as well as on the lower settings and analysis control tool bar. The larger buttons and icons provide a more comfortable visual experience and easier operational control when using tablet computers, 2-in-1 systems or laptops with smaller screen sizes.
Tablet or 2-in-1 computer platforms, properly configured for use with selected portable receiver hardware, can be utilized for advanced mobile or 'walk around' RF data collection and analysis, transmitter search and location, in-field interference analysis and for amplitude direction finding capability. Operators can take full advantage of RadioInspector’s advanced features during mobile field operations including performance signal parameter measurements, harmonic and interpolation analysis, discrete frequency inspection capability, digital signal processing, complete IQ capture with post processing and geographic information support system. Spectrum data collected is automatically written to storage and available immediately for post analysis on the tablet computer, if required.
The compact Wi-Fi Inspector receiver module can also be used with a tablet or 2-in-1 computer for a portable hand held Wi-Fi detection, analysis and location system in support of TSCM, cyber security and network analysis applications.
Summer 2017 has been a very busy time and we were pleased to have had RadioInspector demonstrations provided with the Digital FAR System with Partners Acustek Ltd. and S.E.G. Inc., at the NATIA Conference and Exhibition in Tampa, Florida.
The latest RadioInspector software updates provide a range of new advanced features and program enhancements. Many changes have been made to the software programming in support of the new features during this important update cycle and announcements are now set to begin. Previous new feature additions for 2017 have include extended reference trace options for merging unlimited previously saved traces for use as single reference trace, unlimited user defined spectrum masks, updated post processing for recorded IQ data files of any length, new advanced geographic information support system utilizing Open Street Maps with automatic digital map caching for offline use, recording and storage of geospatial data, mobile route recording and collection point display and automatic frequency correction tables for detected signals and demodulated frequencies. New receiver support has also been confirmed and will be announced in the coming weeks.
RadioInspector is once again being used for educational study at a large cultural
event in the U.S. that attracts tens of thousands of visitors. A monitoring infrastructure has been setup for use with RadioInspector to study wireless patterns, noise and interference during the
event. RadioInspector’s latest software release is being utilized with its leading advanced performance signal parameter measurement, harmonic and intermodulation analysis, live IQ and complete spectrum data recording and post analysis capability.
After months of set up and integration work, an overseas in-place remote spectrum monitoring project with RadioInspector has been completed. The project required monitoring multiple receivers across multiple locations in challenging environments. RadioInspector’s extensive receiver support, live direct control with streaming of all data to remote computers via internal application and simultaneous live monitoring of multiple collection points (receivers), all play key roles in providing highly flexible, advanced capabilities for remote monitoring applications.
are also very pleased to announce a much anticipated Canadian partner agreement

development and training team. Al is a highly experienced and respected TSCM
Technologist and RadioInspector software operator. Al's experience
includes more than 27 years with the Ontario Provincial Police where he had
with Technical Support Services as a
Wire Tapper and Electronic Tracking Court Recognized Expert. Al also
worked as an Electronics Engineering Technologist for Transport Canada in
Communications and Navigational Equipment. Waypoint Counter Surveillance has
enjoyed a close working relationship with Al Doubrough on several fronts during
the past 8 years which now extends to our development and training team.
* Waypoint Counter Surveillance provides government and law enforcement organizations world-wide with sophisticated equipment, software and systems for advanced Technical Surveillance Countermeasures (TSCM), SIGINT, local and remote spectrum monitoring, telecommunications, spectrum management, surveillance and Intelligence applications.
Extended Reference Trace Features
reference trace features have been added to RadioInspector, allowing
operators to merge (combine) multiple previously saved traces by their maximum values, for use as
a single reference trace. Operators can also
display an additional trace (loaded from a previously saved file) which can be
used for visual control when merging multiple traces with the reference trace.
If the frequency band limits or the frequency scan steps in the
loaded or merge trace do not match with the current measurement settings, RadioInspector will interpolate the loaded trace.
The operator can also choose to display the difference trace, which can represent either the current or maximum trace
minus the reference trace. The
operator can display the results as a positive difference or a 2D
difference trace. In addition there is now an option to increase or
decrease the dB level to offset the difference trace for improved visual
The latest extended reference trace features can be used separately with the main spectrum scanning and analysis GUI, advanced RF signal analysis and performance measurement subsystem, or the discrete frequency inspection GUI for increased comparative analysis.
User Defined Spectrum Masks
provides the option to display operator defined spectrum masks, which are overlaid onto the
spectrum scanning GUI. Spectrum mask files can be created as required for individual frequencies or frequency bands, with name and descriptive information and individually or collectively displayed during spectrum scanning and analysis operations. Spectrum masks can also be displayed during post analysis with the
RadioInspector RP post processing program.
Spectrum masks provide a static reference display of predetermined or known frequency spectrum allocations or specific standardized ranges. While this can assist with visual orientation of the spectrum and can help improve overall spectrum awareness, determining with any certainty, whether a signal belongs to a specific standard and is a potential threat, requires proper technical analysis. RadioInspector's extensive list of features including RF signal performance measurement, IQ data and digital signal processing with classification and recognition technology, offers sophisticated and precise signal analysis. The addition of user defined spectrum masks compliments this advanced technical capability.
Note: Digital audio demodulators for DMR, Apco25 and Tetra signals are being finalized and along with audio demodulation and recording, information regarding the address of the receiver, transmitter and service commands will be recorded and displayed in the audio player mode.
Advanced post processing includes performing a digital frequency shift or fine tuning the frequency measurement, digital filtering and re-sampling of source data at a desired frequency rate, decimating original IQ data to a predetermined sampling frequency and applying ‘Windowing’ techniques, providing operators with detailed results for analysis.
* IQ Process is designed as a stand-alone program and does
not require RadioInspector to operate. The program can be downloaded
independently on any computer anywhere in the world, along with saved IQ files
created by any RadioInspector system, for information export and sharing as well
as for additional post analysis.
A similar situation occurs with a frequency receiver, the source of demodulated audio signals. Inaccurate tuning to the frequency of the detected signal (including the frequency shift, relative to the communication standard’s frequency step) leads to deterioration in the quality of signal demodulation.
Occupied Frequency Bandwidth
The sophisticated IQ Process toolkit utilizes a suite of powerful mathematical-based scientific tools to perform a much deeper analysis of Time, Amplitude and Frequency Domain components and the parameters of digital signal packets. Any portion of the recorded IF spectrum can be selected and isolated for post processing and analysis and operators can identify and analyze signals including those close to or obscured by the noise floor, or to help separate signals in dense portions of the spectrum or in close proximity.
Signal detection is only the first step when analyzing spectrum activity and it is the ability to access the data contained within a signal that offers the next generation of advanced professional spectrum analysis. Support for additional communication standards is under development and RadioInspector’s industry leading digital signal analysis capability will continue to expand, providing operators with increasing capability and the actionable intelligence to accurately address real world threats.
The term CSV may also refer to closely related delimiter-separated formats that use different field delimiters, including tab and space-separated values. To address the problems these formats can cause in frequency data exchange, RadioInspector's CSV converter includes options to select values for the delimiter character, string data delimiter symbol and hexadecimal codes.
We are pleased to announce enhancements to the Detected Signals Database, threshold functionality and the latest Signal List Viewer program
Signals that break preset thresholds are automatically saved, creating a detected signals list. The operator can now select the format of the saved file as a RadioInspector specific .risdt format, or in common .csv or .txt formats. This detected signals list includes the Frequency, Occupied Frequency Bandwidth (kHz), Date and Time of Detection, Detection Count, Power Over Threshold (pkWt), Signal Level (operator selected by dBm, dBmkV, dBmV, dBWt, dBmkWt/cm2 or dBWt/m2) and Signal Classification Analysis Recognition System (SCARS) results. The detected signals list also provides the visual spectra or spectrum view for each signal, which is displayed in a separate window with zoom and scroll functions. The spectrum view window shows all recorded data for each individual signal detection count along with the specific instrument used during collection. The spectrum view also allows scrolling through each frequency on the list, or to scroll through each detection count for individual signals recorded over the data collection period. RadioInspector signal lists can be saved manually at any time by the operator or, for mobile, remote or unattended spectrum monitoring, signal Lists can now be saved automatically at operator programmed intervals. Signal Lists can be edited, merged, or shared externally at any time and re-saved as new files, reloaded for additional or new measurement collection, can be exported to or imported from the Authorized Frequency Database and can also be loaded for RadioInspector’s Discrete Frequency Monitoring capability.
