WAVEFORM GENERATOR UNIT MR8790

Waveform Generator Input Module for Control Simulation Testing

The Waveform Generator Unit MR8790 is a plug-and-play module for Hioki Memory HiCorders that offers high-precision DC voltage output for generating signals that simulate voltage fluctuations at very low levels.

Key Features

  • Output sine waves (20 kHz max.) and DC voltage signals up to 4 channels per unit
  • Output signals up ±10V or 5mA
  • For use with Hioki Memory HiCorder series (cannot use with 8847 or MR8847)
  • Isolated between unit and output, and between all channels
