release news – Go2signals 24.1

SIGNAL ANALYZER ENHANCEMENTS

NEW: DEMODULATOR CAPABILITY

When processing a new or unidentified signal, the first step is to analyze its modulati-
on parameters. Signal Analyzer provides all the necessary functions in one easy-to-use 
tool. With this result, the next step is demodulation to obtain the communication 
bitstream for further analysis.

Example with pi/4-DQPSK analysis and demodulation showing results in its bit display

Signal Analyzer now includes the capability to demodulate the signal as part of the analysis. The demodulator incorporates PROCITEC‘s proven demodulators for FSK and PSK modulation types with a wide parameterizable working range and many outstanding features such as adaptive equalization and automatic FSK fading correction. 

 

Example analysis and demodulation of short-duration & burst signals

IMPROVED: SIGNAL INFORMATION DATABASE

With the last release we introduced our new Signal Information Database. With this new version, the information has been updated further and the entries increased to 450 communication signals mainly used in the HF and VUHF frequency ranges and their different modes.

The Signal Information Database captures  around 450 entries of modems and modes

Of course, the users can extend the database with their own information. With the extensive filter functions, measured parameters can be easily matched against known signals to correlate them.


Go2MONITOR ENHANCEMENTS

NEW: PREMIUM MULTI-TRACK AUDIO DEMODULATOR AND PLAYER 

go2MONITOR now includes a premium multi-track audio demodulator and player application as a standard feature. This advanced tool offers a wide range of audio playback and navigation options. Users launch it from go2MONITORs ResultViewer to access one or multiple results and their associated IQ recordings.

Multi-tracking and viewing audio channels from different emissions in the time domain

As default, the tracks are parametrized using available information about the emission from the result database. Additionally, each track can be manually set with its own demodulator parameters such as modulation, squelch, filter bandwidth, BFO-offset etc. 
 

Audio demodulator settings

NEW: MAP DISPLAY COMPONENT

New map display component with new look and user interface. In addition to the built-in or custom offline maps, the users can also access maps from any available server which they have configured  (e.g. global OpenStreetMap servers or local customer servers).

New map display component in ResultViewer

NEW: AUTOMATIC TASK OPTION

Various new automatic task options added to improve task actions stopping control. Task actions can now be additionally stopped based on wideband classification feedback („stop if emission finished“) or on decoder feedback („stop if no modem recognition“ or „stop if modem lost“).

Additional settings for conditional task completion

New automatic task option to limit the number of channels which are used by the task. With this simple parameter the operator can optimize resource usage between different task running in parallel.

Limit channel usage for a task

NEW: RESULTVIEWER WITH NEW FILTER FUNCTION

New filter function in ResultViewer to display all results recently added to the system, regardless of their signal time or frequency („Last added“).

Show last added results

NEW: GO2MONITOR TUTORIALS

At the request of our customers, we are currently creating tutorials to provide an even quicker, easier introduction to the operation of go2MONITOR. Initially, there will be six tutorials, from installation and first steps to manual and automatic processing and evaluation of the results obtained. These tutorials will be available in Q1/2024.

SOMO ENHANCEMENTS

Testing, simulation and training are the main areas of application for SOMO. The software generates a wide range of signaling modulation types with freely configurable parameters and channel simulations.
With the new release, additional constellations for the modulation type QAM have been integrated.

Simulating a frequency sub-band with multiple modulated signals, each transmitting different data

CLASSIFIER ENHANCEMENTS

Initiated in previous releases, we have extended the bandwidth of our classifier for more and more modulation types to signals with up to 50 MBd Symbol Rate.
Release changes:

  • Enhance classification of ASK2/4 signals up to 50 kBd
  • Enhance classification of OQPSK signals up to 50 MBd

 

DECODER AND DEMODULATOR ENHANCEMENTS

With each new release, we add new demodulator and decoder features to our go2signals products to keep pace with the evolving world of signals. The goal is to obtain as much information as possible from all signals received.

Older communications devices using protocols which are assumed to be obsolete are occasionally sourced (most often online from resellers of previously used equipment) and reactivated by unintended
3rd-parties to suit their unorthodox communications needs. Therefore, we intentionally retain these older protocols‘ decoders and simply mark them as ‚obsolete‘ in our go2signals listings. Enduring access to these ‚obsolete‘ decoders enables our customers to react immediately in such cases.
