The Smaller The Bandwidth the lower the noise. Id recommend you try 4 seconds to your highest non-alising freq. But your electronics
needs to match your
hardware and I do not know unless
you build your own how to deal with that.

Subject: Adjusting the period
Hi Folks, I have a Lehman set to 20 seconds..........It seems to be working okay and I don't think it needs any modifications. It
records the same as other Lehmans I have worked with.
I plan on changing the period from 20 seconds to another number, not sure what that number will be. What I want to see, is how it
records at different period settings.
I know the advantages of the 20 seconds. The disadvantage is it misses many other smaller earthquakes.
My question: Before I try other period numbers..........Have you tried this, and what were the results?
I really don't know what the result would be.
