Portable data acquisition systems composed of IBM compatible PC/XT/AT computers and analog to digital conversion cards can be configured with relative ease. These systems have the flexibility for use in a variety of applications. They are inexpensive and offer the added advantage of containing a computer that can be programmed for the reduction and analysis of the acquired data. To demonstrate this versatility, a comparison is made between available analog cards from several different vendors. The specifications and requirements are defined and discussed. Vendor supplied drivers and custom designed software are compared. One system that was recently purchased by the Instrumentation Services Division of the Waterways Experiment Station is described and the custom software is explained. Several caveats that should be considered before configuring such a system are presented.
