SIGNAL ANALYZER ENHANCEMENTS

NEW: TEMPLATE OQPSK ANALYSIS

This template adds additional measurement features specialized on OQPSK modulation analysis. The template includes spectrum of multiple squared signal analysis with marked positions of expected peaks, OQPSK adapted symbol rate measurement, frequency correction analysis for absolute IQ displays, difference phase histogram analysis and absolute and difference IQ displays.
Outstanding is the new feature absolute IQ display of even and odd symbol to check the signal against QPSK signals without any symbol offset.

New: TEMPLATE SQUARED SPECTROGRAM

During a transmission PSK modulated signals often change their valence (e.g. from 2 to 4 or 8). With this new template including signal squaring and spectrogram analysis it is easy to check for this behavior. As this is a typical behavior of some known communication signals, it is relatively straightforward to identify them with a high degree of reliability.

NEW: PRE-PROCESSING MODULE DECHIRP

This pre-processing module allows to demodulate (“un-chirp”) signals using a linear frequency chirp modulation (up or down). With a single keystroke, a new analysis window starts using the demodulated result as input signal. In this way, it is possible to do a full featured analysis for an in-chirp modulation if present.

From left to right:
• Spectrogram of the input signal, selection of the analysis signal range
• Zoom spectrogram with high time resolution showing the chirp modulation
• Spectrogram and instantaneous frequency of the un-chirped signal

ENHANCED: MODULE SYMBOL RATE

The generic measurement module “Symbol Rate” provides various methods for symbol rate estimation. This module is now enhanced with spectrogram analysis to show symbol rate behavior in time.

Go2MONITOR ENHANCEMENTS

ENLARGE WIDEBAND INPUT BANDWIDTH 

go2MONITOR 24.2 now supports the full input bandwidth. The software is only limited by the hardware performance available (e.g. receivers, drivers, CPU performance, memory amount/speed, etc.). Maximum supported range is up to 200 MHz.
Wideband Classifier bandwidth starts from 1 MHz (HF) and 5 MHz (VUHF) with the default license, increasable with option WCL-10 up to 10 MHz (1 MHz HF) or with option WCL-20 up to multiple times of 20 MHz (2.5 MHz HF).

NEW WINDOW LAYOUTS WITH ENHANCED DOCKING WINDOWS

The layout in go2MONITOR can be set in any way you want, simply by docking and undocking its windows. This new release gives users more flexibility than ever to customize the layout to their personal needs

NEW EMITTER TRACKING FEATURES

With go2MONITOR, you can not only receive signals and decode their content, but you can also further evaluate the results and view, edit or discard them before exporting them. To extract the data like position data, the software has a post processor feature running after the signal was received, extracting sender and receiver IDs, position data, and more. For ADS-B signals, the post processing was adapted to extraction airplane positions and their addresses send:

Combine and display the position data from a moving emitter as a track on the map.This function is available for all signals (modem types) with position data. If available, decode the position data directly from the signal or receive it from a connected positioning system.

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.

SOMO ENHANCEMENTS

NEW: OUTPUT SAMPLING RATE NOW CONFIGURABLE

SOMO now includes a new feature that allows you to confi gure the output sampling rate. This increases the output bandwidth of the signal generator by up to 10 MHz, depending on the hardware used.

For example, live generating and streaming of a signal scenario containing five QAM16 modulated signals with different symbol rates in a 5 MHz band. With go2MONITOR, the scenario is classified in the wideband input and in a selected channel.

CLASSIFIER ENHANCEMENTS

The go2signals software offers one of the most comprehensive modulation classifiers on the market. The signal parameters obtained are primarily used for fi ltering according to Signals of Interest (SOIs), but also for recognizing unknown, new signals in both, narrowband and broadband input types. As in previous releases, we have also increased the bandwidth for our classifier for additional signals. In this release for QAM modulation.

Main release changes:

• Enhance classification of QAM 8, 16, 32, 64 signals up to 12.5 MBd
• New classifier for FM-PSK 2, 4, 8, 16 primary modulated PSK signals

RECEIVER SUPPORT

The go2signals software is compatible with a wide range of hardware receivers and direction finders from various vendors on the market (see technical specification monitoring suite on www.procitec.com), including support for VITA49 and ExtIO standardized interfaces. With this release, we added the following new features:

• Plugins and libraries for many receivers were ported to 64-bit
• Rohde & Schwarz EM200 receiver is now supported
• SignalHound SM200 C receiver is now supported

Noteworthy Changes

• Added support for ’Classification Profiles’ to be able to adapt spectrum calculation properties
  and wideband classification settings to specific frequency ranges or use-cases
• Completely redesigned UI elements for selecting and manipulating UI perspectives
• Result XML Export/Import format changed to enable easier integration in other systems.
  Old result exports cannot be imported anymore.
• Application Settings dialog redesigned to better separate UI settings from System settings.
  In distributed systems, all system settings are now stored in the system itself, providing that UI does not have to be started in order to apply the settings.
• New option for audio demodulation in ResultViewer to enable playback of the signal part
  related to the selected result only, instead of playing the whole signal from the beginning.
• Audio demodulation in ResultViewer now considers detected nominal frequency as default audio frequency even if auto mode is not used.
• String filtering in ResultViewer can now be parameterized to be case insensitive
• Standalone ResultViewer (go2MONITOR Result) now includes map server settings in its settings dialog
• The last state of the ’Show only rows with data’ option in a context menu of the ResultDetail
  in ResultViewer is now stored permanently.
• go2MONITOR Result (ResultViewer standalone) now includes a commandline interface to automate its operations by using Python-API, similarly as in go2MONITOR UI
• Python based Commandline options of the UI have been improved and better documented in the manual.
• Post-processing for ADS-B signals is now included, including extraction and display of aircraft positions.
• Clear filter function in ResultViewer can now be customized by the user to define which filter settings will be applied if the filter is cleared.
• Application settings now include an option to determine if the frequency selected in the channel in Decoding mode will be considered as nominal or center frequency
• In Result Export in Scheduler, user can now specify which flag should be used to mark results which has already been exported. That enables using multiple scheduler Result Exports at the same time on the same data.
• Auto-zoom function of the map component now uses system position as default position and uses improved logic
• New map display options in ResultViewer, Table view. It is now possible to display sender positions with fading effect to visualize their order (for example, sender movement), or without labels, to make sure that markers are not covered by labels.
• Function ’Open directory’ for single files inside Result Detail, now highlights that file in the
  opened Explorer window.
• Signal file name is now stored into the Source field in the database for all results from that file, if the file was used as channel input. This function was available only in Bulk File Processing in previous versions.
• UI will now close automatically if there is no connection with the system after 5 minutes
• Removed obsolete ’CIM export’ function
• Find emissions’ function renamed to ’Classify’
• Base station coordinates are now extracted from HFDL/VDL2 decoder results and stored in the database as sender positions in case of base station signals
• Because of modulation name changes throughout the product, some old AMT task exports may not be compatible with this version anymore. This will be the case if Modulation type trigger was used, involving specific voice modulation selection (AM, USB, ...) or FM-Radio modulation type.
