Built-in evaluation procedures

Data processing takes place in subsequent evaluation phases. In the Evaluation window (shown in Figure 5-17a) you can set evaluation parameters as described below in the two subsequent sections and in section 2.2. This command starts the following steps:

The results of this evaluation are written into the following files:

T3STERPROJECT.MRn the smoothed function, the derivative and the time-constant spectrum (if exists),
T3STERPROJECT.CXn the response in the frequency domain (complex locus),
T3STERPROJECT.ZPn the data of the pulse thermal resistance diagram,

where T3STERPROJECT is the file name used to save the measurement results, n is the serial number of the measurement channel (0 .. 7).

The files are alphanumeric and can be easily interpreted. The files are suitable for further processing by a user-written software. The detailed description of the file formats is given in Appendix A.

After the above calculations the structure functions (profile functions) are generated as follows:

In this phase only the "driving point" measurement is evaluated. The algorithm uses the Foster-Cauer transformation for a very detailed (100-180 stages) RC model.

In order to reduce the runtime of the calculation the user can reduce the resolution of the detailed Foster/Cauer model.

The reduction factor can be set in the Evaluation window, in the Resolution tint->Foster: field. The default value is 1. Further possible values are: 2, 3 or 4.

The generated is

T3STERPROJECT.STF

the differential and the cumulative profile function (structure function). The file is suitable for further processing by a user-written software. The detailed description of the file formats is given in Appendix A.

Upon finishing the process of evaluation, the message window shown in Figure 5-17b appears. Pressing the OK button closes both windows.
