go2MONITOR 17.1

by Rolf Haenggi

Release 17.1 July 2017

Version Highlights

  • PACTOR-4
  • Inmarsat Aero
  • New receiver control concept with separate docking views for each receiver panorama spectrum display based on spectra delivered from receivers (implemented for WiNRADiO G33/G39, EM100, IZT R3000 receivers
  • Using multiple wideband input channels from supported receivers (implemented for WiNRADiO G39 and IZT R3000)
  • Added new function for extracting NB-signals from all recordings directly in ResultViewer
  • Old "Recording Viewer" GUI replaced completely through ResultViewer functions
  • Creating and editing user entries in ResultViewer
  • Added selection and multi-selection of results in a signal-Tab of the ResultViewer and various context sensitive functions for selected result
  • Improved editing of values in ResultViewer, Detail-View. Time fields editing added, numerical values editing comfort improved
  • Improved long recordings display in ResultViewer
  • Faster WB-recordings display in ResultViewer if pre computed spectra available
  • Added result type selection for "Show other results" option in ResultViewer, Signal-Tab
  • Pre computed spectra are stored with WB-recordings from SignalServer for faster display
  • File playback options added: History, Playback-Speed and manual editing of center frequency$
  • Additional channel bandwidth added to narrowband channel bandwidth list, equal to the maximal bandwidth which can be extracted from the wideband input (only if less then max allowed channel bandwidth)
  • Default raster for the channel raster option reduced from 1kHz to 100Hz
  • Messaging performance-improvement for large systems with many BCU instances
  • SignalServer wideband recording bandwidth is now limited by the license (default 1MHz, can be increased depending on hardware)
  • SignalServer recordings are now split in max 2GB big WAV-files
  • Added warnings if more than 200 modems are used in one production
  • Double-click on a result in ResultViewer table opens its detail
  • "Del" shortcut not used anymore for deleting items from ResultViewer table
  • Changed frequency axis display for real-values signal (0Hz is the leftmost frequency now)
  • Added support for CodeMeter copy protection

New Release Numbers

All go2SIGNALS products use now the same version number scheme that takes the last 2 digits of the year the release started followed by the release number within that year.
