Abstract
The principle of time domain reflectometry (TDR) is being used by the U.S. Bureau of Mines to monitor strata displacements induced by mining. The Northwestern University TDR Signature Analysis (NUTSA) Program was developed under contract with the Bureau to allow for visual comparison of three TDR waveforms quickly and easily. The program is interactive, and on-line help is available. The Northwestern University Remote Control TDR Data Acquisition System and Modification of Tektronix SP232 Host Application Program (NUMOD) was then developed to allow acquisition of TDR waveforms from a remote cable tester via modem. The NUMOD system utilizes commercially available software while the NUTSA program is available from the Bureau. The report begins with a discussion of TDR principles followed by a description of the NUMOD system. An interactive example of signature analysis is then used to demonstrate features of the NUTSA program.
