Impedance spectroscopy is a powerful experimental technique for complex analyses of electrical response of conducting samples. Experimental setups consist of a wide variety of analyzers and temperature controllers for high and low temperatures, and the experiments may last for days. In this paper, a self-developed controlling software written in C++ and working under GNU Linux that co-operates with many different devices in the laboratory is described. Measurements can be carried out at elevated and low temperatures, using either a furnace or a cryostat, i.e., above 77 K, and to a temperature exceeding 1000 K. The major advantage of this solution is the possibility to freely combine different analyzers and temperature controllers according to actual experimental needs. The possibility to conduct several parallel measurements at one PC makes this software interesting for every well-equipped and intensively used laboratory of impedance spectroscopy.
