In ObserVIEW, users can open, view, and edit time history waveforms, playback time-history data with synchronized audio, video, and GPS, and perform a live analysis of time-history data. The following overview of ObserVIEW navigation will help you to identify where you can perform these actions and more.

Context Help ObserVIEW The question mark icon in the title bar enables Context Help mode. After enabling Content Help mode, click anywhere in ObserVIEW and the software will direct you to the appropriate section of the Help file.

Open, Close, and Save Projects

A project is created in ObserVIEW any time a file is opened or a device is connected. To open a file, select File > Open. Select the Recording (VFW), Project, or File button to open a recording or project. ObserVIEW supports ObserVIEW project, .vfw, .csv, .txt, .rpc, .rsp, and .uff files.

The Recent Files/Recordings pane contains a list of recently opened projects. Choose an item from this list to restore the project to its most recent state.

  • To create a new project, select File > New Project.
  • To save a project, select File > Save Project. The software will save the file with an *.obserproj extension.
  • To close a project, select File > Close Project.

Open file in ObserVIEW


The user will be directed to ObserVIEW’s main page after a waveform is selected. The Main Graph shows graph data as traces and displays a Legend Box, graph title, axes titles, and axes that correspond to each trace. The Summary Graph stretches along the bottom of the application window and displays a summary of the waveform data associated with the selected graph.

ObserVIEW main graph navigation

Click to expand.

Ribbon Menu

A ribbon menu is located at the top of the page, and the Home tab is the default. The subsequent tabs are Editor, Replay, Graph, and Order Analysis.

Main Graph Window

At the center of the page is the main graph window. It displays graph data as lines called traces as well as a legend, a graph title, axes titles, and axes that correspond to each trace in the graph.

To add a new graph, select the Add Graph button in the main ribbon -or- select Add Graph in the main graph window. The graph options include:

Basic Analyzer

  • Waveform
  • Waveform and FFT
  • FFT

Advanced Analyzer

  • PSD
  • Transfer Function
  • Coherence
  • Cross Spectral Density
  • Transmissibility
  • Spectrogram (Time/Frequency)

Order Analysis/STAG

  • Order time
  • Spectrogram (Tach/Frequency)

The user can create multiple graphs with different traces as well as add cursors, copy graph images and data, export the graph as an image, and play through data on the graph.

Summary Graph

Below the main graph window is the summary graph and playback options. As the name suggests, the summary graph displays a summary of the selected graph’s waveform data.


To the right of the main graph window are the Traces pane and Trace Properties pane. In the Trace Properties pane, the user can perform the following:

  • Toggle channel visibility
  • Isolate individual channels
  • Modify trace colors
  • Copy individual traces
  • View trace properties


Cursors are displayed as vertical lines on a graph. Press CTRL + D to enable the cursor pane, which displays the values for the data at the cursor location.

  • Press the Home key to set the location of the base cursor
  • Use the Insert key to add a cursor annotation

  • CTRL + V: Paste
  • Right-click on a graph > Copy Graph
    • Paste Graph as Image to Word
    • Paste Graph as Data to Excel
  • Right-click on a trace > Copy Trace
    • Paste Trace as Data to Excel
    • Paste Trace as Data to Graph
