Everytime I switch from the log. into the lin. scaled Phase, there is a warning like: „Error :6 Überlauf Trace:1 “ , and I ...

Hi everyone,
Why isn´t EASERA saving things like „Hardware Compensation“, „Digital Output Gain“ or „Measurement Notes“ in a user-defined Measurement Setup ?
And another problem for me is how I can s ...

Hi everyone,
how can I estimate the validity of the FFT at low frequencys, depending on the markerd area at the Impuls response.
Our old measuring system ( MLSSA ) shows me the area where the FFT is ...
