ANTEO is the expression of a new philosophy for
a modular exploration seismograph.
The system consists of a single control & display
unit (ANTEO CU) that works together one or more
special cables (ANTEO AD6-x), each one with
no.6x 24 bits A/D converters to be connected to
any standard analogue geophone.
This means that your system can grow from 6 to
any number of channels with the simple
addition of more AD6-x cables, available with
different geophone spacing (5m & 10m standard
spacing, others on request) according to your own
requirements. ANTEO CU will be able to
manage your system from the first 6 channels
to virtually any number of AD6-X connected.
The other great advantage of ANTEO is that the
signal is digitalized (24 bits) directly at the
geophone output, always with the best
Signal/Noise ratio, independently by the geophone
cable length and by any environmental
disturbance.
The digital signal is transmitted to the CU for
display of all traces and the following data
management.
Geophone connected to AD6-X
ANTEO’s CU User Interface
ANTEO CU can be positioned at any AD6-x
connection along the spreading: it will
automatically recognise and count all geophones,
performing the geophone tests and assuring you
everything is OK before you start the acquisition.
The real time noise monitor function will allow
you to choose the best moment to shot.
The built-in roll-a-long function is easy to man-age due to the extreme modularity of the system.
