The HSE-HA-BDAS software is an easy data acquisition software for measuring relatively slow moving signals where only a mean value is of interest such as temperature, pH, pO2, pCO2, pK+, mean flow, mean pressure, smooth muscle contraction... under Microsoft® Windows® NT/2000/ or XP operating system. The software is very flexible and user-friendly. It saves the digitized raw signals on the hard disk and calculates online the mean values of these signals.

The HSE-HA BDAS software can be adapted to virtually any experimental investigation where slow signals are measured, eg. measuring oxygen consumption of cells in a cell chamber with a Clark electrode, measuring of up to 16 temperatures, measuring up to 16 pH values, measuring pH, pO2, pCO2, K+ concentrations in isolated organ experiments, measuring of static pressures, measuring contraction forces of smooth muscles... During data acquisition all acquired signals and derived parameters are displayed on the screen.

The configuration of the system is defined in configuration files to reduce the amount of necessary settings and to ensure a stable and secure system. The user only has to calibrate the signals and to fix the graphics scaling, all the hardware definitions and the algorithms used are defined in these configuration files. This reduces the amount of information necessary in the SOP's and the possibilities of wrong settings. The configuration files can of course be changed and the software can be used in combination with a set of different configuration files to match the different experiments.

The HSE-HA-BDAS software has a maximum of 16 channels, i.e. up to 16 different raw signals can be handled. The assignment of the signals to the individual channels is determined in the configuration files. The sample rate, the type of signals and the algorithm used for analysis are also defined in the configuration file. The arrangement of the graphic detail (raw signals) and trend (calculated parameters) is defined in the menu. The user has only to set up which of the available signals he wants to acquire and display, which of the possible parameters he wants to evaluate and display; to enter the experimental protocol and finally to calibrate before he starts the data acquisition.

The HSE-HA Data Acquisition Hardware for BDAS Software is available in three versions:

• PLUGSYS Version 73-0161

This version consists of the PCI A/D board DT301, ROM-DL, DIM and the cable for connecting to a DIM Data Interface Module installed in the PLUGSYS basic system case.
• Stand Alone Version 73-0235

This version consists of the PCI A/D board DT301, cable and a BNC input box where signals from external amplifiers can be connected.

• Stand Alone USB Version 73-3330
