2.6.9. Online Analysis
MultiLab enables you to analyze data from a live experiment and to display the
analysis function in the graph window, as the data is being recorded and processed.
To execute online analysis, you will first have to use the Analysis Wizard to define
the function to be used, and then edit the graph in order to display the function (see
page 46).
For example, here is how to set up an online envelope (amplitude) function of data,
recorded with a Voltage sensor connected to Input 1:
1. Click Analysis Wizard on the main toolbar to open the
Analysis Wizard dialog box:
Figure 22: Analysis Wizard – online functions
2. Select Envelope (upper ) from the Functions list.
3. Select Input 1: Voltage from the G1 drop list.
4. Click OK .
