Description
The 6065 is a two-channel instrumentation amplifier-digitizer module. Each channel has isolated input, 100 kHz bandwidth and two outputs that can be filtered or wideband.
The input is two-wire shielded and is 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 isolation provides for operation with up to ±300 Volts of common mode applied to the input.
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 and wideband. An optional four-pole Bessel filter has continuously programmable bandwidth with 1 Hz resolution below 1 kHz and 5 Hz above 1 kHz. Each channel has two buffered, ±10 Volt outputs. The output can be digitally monitored using any of the supported interfaces.
Voltage substitution calibration, employing an external standard, is provided for gain calibration. Automatic zero and gain calibration are implemented in PI660 software.
