Channel modules that plug into the 3 or 16-channel recorder condition, amplify, filter, digitize and store the transducer signals. Simultaneous sampling provides excellent time correlation between channels and external events. The digitizer has 14, 16 or 24-bit resolution and sample rates programmable up to 2 Million samples per second.
Each channel has two inputs, one for bridges, RTDs, potentiometers and thermocouples; the other AC coupled with 1 to 20 mA current source for transducers with built-in electronics. Signal conditioning includes programmable excitation and completion for ¼, ½ and full bridge, AC-coupling, automatic balance, voltage and four-step shunt calibration, programmable gain and a four frequency,
eight-pole filter.
