IntermodAnalyzer


RF Spectrum Analyzer & Frequency Coordination Software for RTLSDR Receivers

Precise, Wideband RF Spectrum Scanning, Visualization and Intermodulation Analysis


IntermodAnalyzer is a low-cost, RF diagnostic software tool for RTLSDR (RTL2832U) receivers -- specifically designed for the wireless professional audio field.  IntermodAnalyzer is the industry's first, RTLSDR-based tool to offer RF spectrum analysis, intermodulation analysis and automatic charting of open white space for use with wireless audio gear -- all built into a single application.  IntermodAnalyzers' unique combination of features -- RF spectrum analysis plus intermodulation analysis -- make it an extremely versatile and powerful tool, one that extends beyond the bounds of traditional RF analyzers.

IntermodAnalyzer turns data collected from RTLSDR receivers (RTL2832U) into graphical charts and displays in real time, enabling users to more readily visualize the RF environment, monitor RF signals, troubleshoot RF issues, and detect sources of RF interference.  Intermodulation analysis generates Smart Frequency Sets for use in frequency coordination -- assigning the most reliable frequencies to your wireless audio gear.

IntermodAnalyzer offers a variety of diagnostic views of the data captured by the RF Explorer device. Employing multiple views of the data enhances your ability to gain a better understanding of the local, RF landscape.  Furthermore, IntermodAnalyzers' intermodulation analysis sets itself apart from all other diagnostic software by generating and monitoring Smart Frequency Sets.  A Smart Frequency Set is used for frequency coordination and assigning the most reliable frequencies to your wireless audio gear.



Spectrum Trace View

Continuously scans and samples the relative signal strength (dB) of frequencies in the range the user has specified.  In the 'Spectrum Trace' view the relative signal strength data (in dB) is displayed as a function of frequency.  The high resolution view uses a step-size of approximately 25 KHz.


Waterfall History

Provides a color-based visualization of the RF level and activity over time.  As signal levels for specific frequencies or frequency ranges increase and decrease, the waterfall map varies its colors. This feature provides a quick glance back into the sweep history to identify aberrations or fluctuation in frequency levels.


Density Map

Displays accumulated RF energy as a function of frequency.  The power of the relative signal strength in dB is shown across the frequency span.  Over time, this spectral view will approximate the steady-state RF energy signature of a given environment.


Threshold Trace

Highlights those frequencies whose signal strength exceeds a user-defined threshold. This feature is especially useful for visually emphasizing strong signals (and deemphasizing weak ones), where the user gets to define 'strong' and 'weak' according to where they set the threshold.


Delta Trace

Used to view small (or large) changes in the RF spectrum over time.  Plotting the data in this way makes it easy to detect RF changes that occurred since the initial 'snapshot'.


Monitored Frequencies

Monitor specific frequencies over time and highlight occurrences where signal strength exceeds a user-defined threshold.


Monitored Bands

Monitor specific bands over time and highlight occurrences where signal strength exceeds a user-defined threshold.


Intermodulation Analysis

Generates and monitors Smart Frequency Set used for frequency coordination and assigning the most reliable frequencies to your audio gear.
