What can go2signals Signal Analysis Software do for you?

Monitoring Capabilities

With go2signals software, you have a comprehensive set of capabilities for processing communication signals at your fingertips. The software provides a central platform to gather a complete understanding of all signals received, covering the frequency range from SLF to SHF and specializing in the HF and VUHF frequency domains.

  • Radio Monitoring with go2signals - monitor entire frequency bands and automatically detect, intercept, classify, demodulate, and decode hundreds of signals simultaneously.
  • Data Acquisition & Collection
    • Complex digital I/Q signals through streaming or receiver
    • Digital IF/AF recordings
  • Easily connect with receivers through existing drivers or open interfaces, such as ExtlO or VITA 49

Automatic Signal Search Monitoring

go2signals software offers a fully automated solution for monitoring signals. The tool performs detection, modulation classification, recognition, and decoding of radio signal emissions in a job-based manner. Used in conjunction with wideband monitoring receivers, go2signals provides a comprehensive feature set.

Classified signal activities are analyzed and technical parameters are determined. The software automatically analyzes received signals, records and demodulates them to live audio, and decodes the transmitted information. All analysis results and data are stored in the software's database.

  • Automatically monitor complex signals scenarios over a broad range of frequencies
  • Identify Signals Of Interest (SOI) faster and react more quickly
  • Save time through the automation of processing chains
  • Optimize operator workload by focusing on new and unidentified emissions.

Multichannel Processing

Multichannel processing enables confident handling of wideband signal input bands, with the ability to process multiple signals simultaneously. The number of processing channels can be increased to several hundreds, allowing the software to automatically demodulate and decode hundreds of signals in parallel.

Each processing channel offers full processing features, including classification, recording, demodulation, and decoding. With multichannel processing, no signals are lost, even in highly occupied frequency bands. The go2signals software has a large decoder library, including 35 different demodulators and over 200 decoders supporting more than 350 modem types.

New features and decoders are added with each release to keep up with changing signals.

Manual and Automatic Modes

You are free to choose between manual and automatic operation: whether manual signal processing and rapid analysis of a single signal, or fully automatic search, intercept, and processing of signals. go2signals supports different processing modes to meet user needs, including live monitoring, offline processing of results, fully automatic processing, manual control, or a combination of these.

  • Control missions and tasks using operator-defined prioritization
  • Define tasks and plan missions, including setting triggers and start/stop criteria
  • Alert based on signal events (pop-up display)
  • Schedule routine tasks for automatic execution at user-defined intervals
  • Automatically process large customer-derived signal recording libraries (mass file data) with Bulk File Processing


The internal results database stores all results, meta-data, content, and recordings from "Detection and Classification" and "Multichannel Processing". Automatic post-processing scripts, whether specific to the modem or the protocol, extract important information from decoded text, such as sender and recipient IDs or position data. To work on analysis results, the go2signals software includes the ResultViewer, a special tool for filtering, displaying, replaying, tagging, structuring, editing, combining, and exporting results to help build the big picture.

  • View results from multiple production channels, including recorded I/Q data, demodulated audio files
  • Keep track of progress: use the offline spectrogram to navigate quickly through recorded signal scenarios.


In addition to real-time decoding and demodulation of relevant signals, it is crucial to keep a record of new or previously unknown signals for more in-depth analysis using signal analysis software offline. The recordings can be scrutinized, and decoders can be developed or customer-created decoders installed to improve the software's automatic performance.

  • Capture I/Q data from both wideband inputs and narrowband channels simultaneously, and record both demodulated and decoded audio.
  • Make lossless recordings for documentation or further processing purposes.
