PPSD with no available Response Information

Hello, I would like to compute the PPSD for a signal acquired with a digital MEMS accelerometer. The signal I have is expressed in gs, and I have no instrument reponse information/StationXML file to pass to the PPSD function.

Is there any way I can obtain the PPSD from just the signal I have using the Obspy function?

You could always pass a unity response. NRL in obspy. You would want to use the generic response and the generic digitizer: Generic Sensor.
