What is a virtual recorder?
Basically a virtual recorder is a transformation of data that was collected in a real recorder. There are many types of transformations that can be used ranging from a simple grouping of channels to completely synthetic data. The main concept behind the virtual recorder is to allow the user more complete control of the data. If you have ever wanted to see a plot of the difference between the X and Y axis then the virtual recorder was designed for you. Another useful exercise would be to plot unfiltered data layered with the same data filtered different ways. This can be accomplished by creating a virtual recorder with unfiltered data in one channel and the various filters that you are interested in applied on the data when creating the other channels in that set.
