Background info:Now to the actual question:
A TEF20 has been temporarily provided to my company for the development of a test system. Triggering the measurement and evaluating the result is supposed to happen fully automatically, therefore we are NOT using TEF SoundLab software. Instead, in order to communicate to the TEF, data is being transferred from/to the TEF in a C program. We have a piece of code that triggers the frequency sweep and receives a set of data (e.g. 512 data points) back from the TEF. Our understanding is that this data represents the Energy-Time-Curve. But what is the time scale of the resulting ETC curve? How can we calculate the time resolution of the ETC curve from the input parameters (start freq., stop freq., number of sample points, etc.)? P.S.: I think we found it... TimeSpan = (1000 * 8.5 * number of samples) / (2 * (StopFreq-StartFreq))

I believe that is correct, you can verify it with Louis at Goldline.
