Abstract
Results of impedance measurements of a non-stationary model electric system are presented. Impedance measurements were realised by the pseudo-white noise technique. Simultaneous time–frequency analysis of the response signal was performed using the short-time Fourier transformation method. It is shown that the measurement method correctly reflects changes of the system investigated in the time and frequency domains.
Microsoft is Ending Support for Windows 7
Microsoft will discontinue support for Windows 7 on January 14, 2020 which means Gamry will also be discontinuing support for Windows 7. If you are upgrading to Windows 10, like many companies and institutions, you need to be running Version 7 of our s oftware . Please note that only USB and Ethernet-based instruments can run in Version 7. Eligible users can download the latest version of our software through our online Client Portal .
If you haven't already registered your instrument, you can do so through the Client Portal .
Please email Technical Support if you have any questions regarding this transition. Please be sure to include your instrument model and serial number when contacting us.
