big shattering in vodoo`s second preamp signal

[Levin]

Ok thanks.
I thought that I figure out the correct main sample delay by watching tp 3/5 in the scope and and reading out the correct delay. it that True ? But my not transportable scope is indoor and my deteckor and my testcoil doesnt have a "outdoor housing" too. Can I figure out the sample delay indoor too or give it alternativs too get the correct sample delay ?
best regards Levin

You are over-thinking the problem. Just leave the main sample delay as the default setting of 27us. That will allow you to complete the initial testing.
Then later (in the field) you can gradually reduce the delay until the response to your test target gets worse. At that point you will have found the minimum sample delay for that particular coil.
