To alert the user about specific data values and thresholds, BioBench incorporates userdefined
alarms for each signal displayed. Alarms appear on the user interface during data
acquisition and notify the user if an alarm condition has occurred.
Figure 136-20 is an example of the Data Acquisition mode of BioBench.
Once data have been acquired, BioBench can employ a wide array of easy-to-use analysis
features. The user has the choice of importing recently acquired data or opening a data
file that had been acquired for comparison or teaching purposes. Once a data set has been
selected and opened, BioBench allows the user simply to select and highlight a region of
interest and to choose the analysis options to perform a specific routine.
BioBench implements a wide array of scalar and array analyses. For example, scalaranalysis
tools will determine the minimum, maximum, mean, integral, and slope of a
selected data set, while the array analysis tools can employ Fast Fourier Transforms
(FFTs), peak detection, histograms, and X-versus-Y plots The ability to compare multiple data files is important in analysis, and BioBench allows
the user to open an unlimited number of data files for simultaneous comparison and analysis.
All data files can be scanned using BioBench’s search tools in which the user can search
for particular events that are associated with areas of interest. In addition, BioBench allows
the user to employ filters and transformations to their data sets, and all logged data can be
easily exported to a spreadsheet or database for further analysis. Finally, any signal acquired
with BioBench can be played back, thus taking lab experience into the classroom. Figure
