Precision signal analysis and extraction for RF spectrum data

RFeye DeepView software is the ultimate signal extraction tool. Its robust indexing feature allows users to sift through multi-terabyte datasets and quickly find and export signals of interest (SOIs). DeepView extracts SOIs in as small a file as possible, slicing file snippets using both time and frequency limiters to facilitate rapid file transport and smarter data management.

Designed for use with the SenS Portable I/Q recorder, DeepView captures hours or days of full-rate, 16-bit I/Q data in real time, up to 100 MHz per receiver channel. The low noise figure and phase noise of the SenS Portable recorder provides unparalleled signal fidelity, enabling users to find and analyze mission-critical signals, including narrow- or wideband, low-power, short-pulsed, co-channel or even frequency-hopping signals.

DeepView doesn’t just capture and extract high-value signals; it also fits into existing ecosystems with minimal effort. With multiple file formats to support third-party software systems, it lets you conduct advanced signal analysis including decryption and demodulation for COMINT.

RFeye DeepView extracts your most important signals with surgical precision, preserving crucial signals of interest with pristine clarity. With interoperability support, DeepView fits into your existing architecture to save you time and money.

Multiple signal views

There are five signal views available in RFeye DeepView’s spectrum overview:

  1. Dataset Overview
  2. Analysis Region Overview
  3. Analysis Region Spectrum
  4. Time Cursor Spectrum
  5. Power/Time chart

Once you have found a signal of interest, you can take measurements of the frequency and duration and export the I/Q of the signal for further analysis or demodulation.

When you need to find a transmission within the congested RF spectrum, DeepView gives you the power to quickly and easily discover, analyze and extract signals of interest.


Displays the overview of all the I/Q data currently loaded for analysis, plotting time against frequency. Selecting a particular region here allows you to view it in the Analysis Region Overview chart for analysis in greater detail.

1. Dataset Overview chart


This displays the spectrogram of the dataset currently selected in the Dataset Overview. Plots time against frequency. Changes in other charts are reflected here, while changes here in the Analysis Region Overview will also carry over to the other charts.

2. Analysis Region Overview chart


Displays a heatmap of the analysis region selected in the Dataset Overview or other charts, plotting power against frequency.

3. Analysis Region Spectrum chart

Displays the spectrum snapshot selected in the Analysis Region Overview and the Power/Time charts. Plots power against frequency. The data displayed in the chart reflects the spectrum at a particular time slot depending on the position of the time cursor in the other two charts.

4. Time Cursor Spectrum chart

This displays the region selected in the Dataset Overview. It also shows a time cursor that can be dragged to a desired location using the mouse.

5. Power/Time chart
  • View terabytes of I/Q data as a time spectrogram and as a spectrum heatmap
  • Live, on-the-fly analysis builds an overall recording index for immediate post-processing scanning and analysis
  • Interactively zoom and scroll in real time down to individual sample level
  • Export digitally tuned and filtered sections of I/Q data with no export size limit
  • Comprehensive and correlated analysis of time/frequency/amplitude/phase information for signals of interest
  • Play back the whole dataset or selected sections of I/Q data
  • Load single I/Q files or complete directories
  • Open multiple datasets simultaneously
  • Marker and delta-marker functionality shared with the live recording view
  • No limitation on overall file duration
  • Supported read/write file types: XDAT, SIQ and RFIQ
  • JSON data export from charts

DeepView is a Windows desktop application and for best performance requires a high-specification PC or Windows server:

We highly recommend purchasing the PC through CRFS to ensure Thunderbolt compatibility. This option allows end users to start recording right out of the box using a pre-configured, fully tested system.
