Model 6028, 8-Channel Voltage Digitizer with Filter



Features

  • Differential input, ±10 Volts, ±50 Volts with optional attenuator
  • Buffered ±10 Volts analog outputs for redundancy
  • Four-pole filter, 100 Hz to 20 kHz
  • Up to 100 kS/s per channel with 16-bit digitizer
  • Two alarms with programmable upper and lower limits

Description

The 6028 input module has eight channels each with a differential input, unity gain instrumentation amplifier, low pass filter and 16-bit analog to digital converter. Each channel is capable of digitizing high-frequency signals at up to 100,000 samples per second. In addition each channel has a continuous, wideband analog output.

The 6028 is used to digitize high level signals, usually the output of signal conditioning amplifiers or other measuring instruments. The four-pole filters may be employed to prevent alias errors in the sampled data and are available with bandwidths from 100 Hz to 20 kHz. The ADC-per-channel architecture provides sampling rates up to 100 kS/s with 50 nS time correlation between data sampled on different channels.

The differential inputs have 50 Megohm input impedance, 80 dB common mode rejection, and are protected to ±50 Volts. Zero and gain calibrations are automatic. Up to four programmable alarm limits are provided and checked each time the output is digitized. The high-level analog outputs provide a means to independently monitor and record each channel.
