Among many experiments involving time domain analysis, the device lifetime measurement is relatively a long-term test for the practical purpose of estimating product lifetime and of understanding failure mechanism. Generally in long-term tests, devices..

“Transient” is a process of transition before the system reaches a steady-state condition due to external stimulation. The transient itself does not mean nonlinearity because it is a kind of general phenomena even in linear systems such as overshooting, underdamping, and phase shift upon..

Frequency Response Analysis (FRA) is a common AC technique for nonlinear device characterization. While the I-V characterizaton is basically a DC technique for measurement at steady-state conditions, further information on device characteristics at dynamic conditions..

The I-V characterization, a relationship between electrical current and voltage, is a basic and common method for nonlinear device characterization. If a system is linear then electrical current is proportional to applied voltage, and the inverse of linear coefficient we..

The experiment automation using computers is essential to guarantee measurement accuracy and reproducibility and to avoid human errors and limitations. A series of experimental steps, such as setting test conditions, operating instrument and performing measurement at right timing, data..

McScience’s test systems employ various optical measurement technologies. Many types of devices under test such as display or photovoltaic devices for instance, are involving optical characteristics and require optical measurement as an essential test part..

Voltage and current are basic elements of electrical measurement. These two have an inseparable relationship, which signifies interdependence of control between two elements, so if you change one element then the other changes automatically and behaves responsive.

Just drop a piece of stone, if you are going to figure out how deep the water is inside the well. One can easily estmate depth of the well and the amount of filled water by counting time to reach the water and hearing sound of splash.
