The following modes of recording are available: 1. Continuous Recording Signals are recorded continuously until the recording is stopped. It is possible to online process signals while recording continuously. This mode is used e.g. for the cycle plot processing. 2. Triggered Recording The triggered recording is based on the existence of a digital trigger signal. If the Record button is pressed, signals are only recorded if a digital trigger value is > 0. For the generation of digital trigger signals, STIMULI can be used. The stimulus generation program defines the duration of the digital trigger signals and therefore the length of the recorded signal piece. In addition to the length of the digital trigger signal, the recording can start before the occurence of the digital trigger. The pre-trigger time and the record type is defined in the Setup window. Online Processing If an online processing is chosen in the Setup window, two channels are selected which are cut according to a specific digital trigger value. The online processing is restricted to two channels and one corresponding digital trigger value per channel. This restriction to two channels is obsolete for the additional online recording windows which open after the recording is finished. There all channels and all trigger conditions can be viewed and written to text files which can be imported to Excel for further examinations.
