NetForce Software for Ethernet Data Acquisition
NetForce
is the ideal companion for AMTI’s Ethernet enabled data acquisition product
line. NetForce interfaces directly with
our DigiAmp and DigiVolt instruments providing a highly integrated data
acquisition system. The NetForce
Ethernet interface provides synchronization and acquisition of data from up to
six DigiAmp and DigiVolt instruments interconnected via a single simple
Ethernet cable. AMTI’s DigiAmp
instrument provides six channels of high stability, high gain signal
conditioning ideally suited for the acquisition of data from our multiaxis
force transducers or other strain gage bridge devices. AMTI’s DigiVolt provides a 12 channel signal
conditioning and data acquisition front end for high level analog signals (±10 volt) originating from instruments such as EMG isolation
amplifiers and other user equipment.
The
NetForce Ethernet interface provides a high level of system integration not
available with traditional data acquisition cards and stand alone analog
amplifiers. Software selectable filter
cutoff frequency, software selectable amplifier gains and software selectable
excitation voltages ensure you that the amplifier hardware settings match the
acquisition software settings. Digital
filter settings from 10 Hz to 1000 Hz allow you to optimize your acquisition
process for the given application to give you the lowest possible noise. To see the many additional features of the
DigiAmp and DigiVolt products please visit our Instrumentation home
