Figure 136-19 illustrates a typical setup of a data acquisition experiment using BioBench.
BioBench also features pull-down menus through which the user can configure devices.
Therefore, those who have made large capital investments can easily migrate their existing
equipment into the Computer Age. Integrating a combination of old and new physiological
instruments from a variety of manufacturers is an important and straightforward
procedure. In fact, within the clinical and research settings, it is a common requirement
to be able to acquire multiple physiological signals from a variety of medical devices and
instruments that do not necessarily communicate with each other. Often, this situation is
compounded by the fact that end-users would like to be able to view and analyze an entire
waveform and not just an average value. In order to accomplish this, the end-user must
acquire multiple channels of data at a relatively high sampling rate and have the ability to
manage many large data files. BioBench can collect up to 16 channels simultaneously at
a sampling rate of 1000 Hz per channel. Files are stored in an efficient binary format that
significantly reduces the amount of hard disk and memory requirements of the PC.
During data acquisition, a number of features are available to the end-user. These features
include Data Logging, Event Logging, and Alarming
