Online Processing means cutting signal pieces of specific channels and specific digital triggers and generating the mean of these signal pieces while recording. Since the space on the screen is limited, only two signal pieces, each with a specific digital trigger value, can be viewed online while recording. After the recording is finished, an additional window occurs which shows all channels and all trigger conditions and can export all results to a text file for further examination. In general the functionality of the screens while recording and after recording are nearly identical. The main difference is that a rotating buffer is used while recording which stores the last X signal pieces for the online processing. This allows a moving average. In the Online processing window after recording all signal pieces which have been selected are processed. Also all trigger conditions and channels are available. Sometimes it is necessary to have a preprocessing before being able to use the standard processing chains available in IMAGO Record online processing. You can therefore use the Process Master for the preprocessing and store the results in the Binary format. With the modified binary file you can use the powerful functions of IMAGO Record.
