Let us first have a look at the data processing during the stage of recording. After the data has been captured by the MediaLB® Monitor it is transferred via USB to the central event buffer of OptoLyzer Suite on the PC. Here, you can reduce the amount of events which actually go into the central event buffer by configuring Pre-filters and Pre-Triggers.
In most cases it is helpful to activate High-Level-Protocols, a software feature which inserts additional MediaLB®-Transmission events into the central event buffer. From the central event buffer the events are either shown in a Viewer or they can be directly recorded in files. At this stage you can conveniently select the desired data, by setting Filters and Triggers.
What is the main difference between Pre-Filtering on the MediaLB® Monitor side and Filtering in a Viewer?
The latter one can be switched on or off as needed, even during subsequent analysis, whereas Pre-Filters prevent that certain events are recorded at all, which means that those events are lost….
