Hy Admin, i looked not intensively for something related to "site resonance". Every reading conducted to HV ratio. I will look better. If a see some peek in the spectrum of an acquired signal, it is easy to conduct it to an external peridoic noise that has lasted for a good portion of time...

Hy. Yes, what is shown is the spectrum of x,y and z components. But it is not the same as the spectrum of the original signal. The signal present in the original saf file does not give any information. What is triggering my interest is the presence of a continuous frequency that should be in the ori...

In the bottom left you can see what should be the resonant freque...

I have developped a new way to try to measure the resonance site frequency (if this is the correct way to call it). I elaborate a saf file, whose improves the measure. The responce from the app based on this idea is sometimes in contrast with what you get from the HV curve, evaluated in the usual wa...

Hy, thanks for your reply. In the meanwhile, after a lot of investigation, i've found exactely what you are saying. I've have found that even the START_TIME must be in the correct format: yar, month, day,hour seconds and these values must be consistent. The file has been generated by Dolang devices ...

When i load a file.saf, i get this error: bad samplig frequency

I have the geopsy version 3.2.0 geopsypack 3.2.2

The file.saf has been sent by email beacouse i cannot attach it, even zipped.
Best regards, Enzo
