DESCRIPTION
The 6060 is a two-channel 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
unbalances 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 from 4Hz to 20Hz.
A “features card” provides shunt calibration using dedicated
inputs. Two-step, resistive shunt calibration is standard. Four step
shunt calibration and DAC shunt with
16-bit resolution are also available. Voltage substitution
using an external reference is provided for traceable gain
calibration.
