WinQuake can be used to check the period. What you need to do is remove the damping and record some data after exciting the boom. You then load the "event" file into WinQuake and do an FFT. The FFT plot should have a peak at the period of your sensor. -Larry Cochrane Redwood City, PSN At 07:45 PM 8/2/00 -0700, you wrote: >Is there a simple way to determine the period of a Lehman Seismograph in >Winquake?
