changed levels according to use of MiniCircuits Splitters ZFRSC-123+ which have ~ 6 + 3,75 dB attenuation (~ factor 3).

Nowadays we are at scipy.__version__ 0.17.0 which failed to define "argrelmax". "if 1" always define!

adjusted DSO input and trigger levels to 100mV/dic and 50 mV trigger (using multi circuits ZFRSC-123-S+ splitter)
