The 6060GV is a two-channel Galvanically isolated signal conditioning amplifier-digitizer module with 50 kHz or 100 kHz bandwidth and both digitized and analog outputs. The bridge input is ten-wire shielded with programmable constant voltage or constant current excitation and programmable completion for quarter, half and full bridge transducers. Automatic bridge balancing accommodates large imbalances without limiting dynamic range.
The input and excitation are isolated from the outputs, power and control interface. This gives the user complete freedom to ground the input without creating ground loops that introduce noise and offset errors.
The differential instrumentation amplifier has programmable gains from 1 to 5,000 and automatic zero. The standard filter is a six-pole Bessel with four programmable bandwidths. An optional four-pole Bessel filter has continuously programmable bandwidth. The filter output is digitized to 16 bits at up to 200 kS/s.
A “features card” provides shunt calibration using dedicated inputs. Two-step, resistive shunt calibration is standard. Four-step shunt calibration and simulated shunt using a DAC with 16-bit resolution are also available. Voltage substitution using an external source is provided for traceable gain calibration.
