Preview Of Upcoming Artemis 3.0 Release

With the release of ArtemiS 3.0 many exciting and practical features have been added. Some of the key features include

• Analysis vs. Channels. This allows any of the channels to be designated as a control channel for the analysis of another channels. A typical application of this is to have a tachometer signal recorded as a data channel and use the data for Spectrum vs. Time or Order Analyses. The control channel could also be some slowly changing parameter such as temperature or pressure.
  
  
• Another way a tachometer control signal may now be generated is by using a special cursor feature in the Mark Editor. While viewing a Spectrum vs. Time plot, you can use the cursor to connect the dots along a dominant peak that relates to a rotational order (typically the firing frequency of an engine). ArtemiS then calculates the RPM vs. Time curve so that it may be used for RPM related analyses. See the diagram below for an example.
  
  
  
  
  
  
• The use of the 3-D cuts in the Mark Analyzer have been improved to add animation. While in the 3-D cut mode, if the Play function is chosen, the cuts move automatically in accordance with the cursor position. This function works for both Time and RPM based analyses.
  
  
• The affects of IIR filters on the analyses as well as the filter shape may now be seen in real time via the filter morphing function. The analyses and filter shape are updated instantaneously as the filter cursor is moved up and down in frequency. See diagram below for an example.
  
  
  
  
• The FIR capabilities have been extended to allow the import of tabular data such as from an Excel spreadsheet to define the filter shape. An example is shown below that imports octave data from an Excel file to define a new FIR shape.
  
  
• An overall level may now be plotted automatically along with the selected Order cuts. This is done by choosing "Order 0" under Properties/Representation/ 2. Abscissa Cut.
  
  
• Excel Export with Representation Settings. The Representation Settings for an analysis will now determine how much of the data is exported to Excel. For example, if you selected a limited frequency range under Representation, only data in the selected range will be exported.
  
  
• Packages in Filter & Statistic Pool are now available to allow multiple filters or statistic functions to be used in series. For example, if you wanted to get an average of several files and then compute a vector sum of several of the averaged channels, you can combine the Averaging Function with the Channel Calc function in the Statistics Pool.
  
  
• Other new ArtemiS features include:
  • Smoothing function for plot curves.
  • "Mark Editing" may now be accomplished in the Mark Analyzer instead of the Mark Editor.
  • Remote Control of ArtemiS operations via the COM interface and Option ATP 13, ArtemiS Programming Module.
  • Show pulses function in the Mark Analyzer & Editor
  • Fluctuation Strength improved
  • Articulation Index according to ANSI
  • Support of the TEAC GX 1 as a Frontend
