I am getting significantly different results with the attached .dwf3work file that was created using WaveForms v3.9.1 and is now being used with v3.10.9. The 3 images below are:
Version 3.9.1 results.
Open the .dwf3work file in WaveForms 3.10.9. Turn on the Factor window to see Quality and Dissipation. Adjust window size and position. So far things look good and the results from the previous v3.9.1 measurement are shown as expected.
Run the Impedance measurement in v3.10.9.
There are several differences in the v3.10.9 results. Perhaps these come from a common problem, but what is wrong?
The Input window trace changed from attenuation (0 to +27 dB) to something I don't understand with values from +60 to -30 dB. (I had to re-scale to get these values.)
In the Impedance window, the Rs results changed dramatically.
In the Admittance window, the Gp results changed dramatically.
In the Factor window, Quality and Dissipation results changed dramatically.
In the Nyquist pane, the results changed dramatically.
