ARBITRARY WAVEFORM GENERATOR UNIT U8793

Output signals measured with a Memory HiCorder to simulate anomalous events for scenario testing

The Arbitrary Waveform Generator Unit U8793 is a plug-and-play module for the Hioki Memory HiCorder to create a function generator, arbitrary waveform generator, and waveform measurement in a single device.   Easily observe waveforms while varying test conditions, such as changing the signal's amplitude and frequency as well as programming various waveforms to output in order.

Key Features

  • Output arbitrary waveform signals up to 2 channels
  • Output problematic waveforms recorded with the Memory HiCorder up to 15 V
  • Output customized arbitrary waveforms signals up to 15 V
  • For use with Hioki Memory HiCorder series (cannot use with 8847 or MR8847)
  • Built-in function generator and sweep function
  • Isolated between unit and output, and between all channels

Model No. (Order Code)

Note: This module must be used with the Memory HiCorder. Output cords are not included. Please purchase them separately.

Waveform Maker Software included

After you install the included SF8000 Waveform Maker software on your computer, you can create waveforms easily by either entering them directly or by entering the formulas behind them. You can also quickly add noise and multiply waveforms.

Anomaly Simulation

Reproduce and output the observed waveforms without modification. When resolving problems observed during research or development, you can reproduce such problems for efficient testing. For example, you could output actual waveforms recorded from a car without modification, and then use them for standalone testing. You can also generate isolated output of up to 15 V while varying the signal’s amplitude and frequency without using a generator or amplifier, which is traditionally necessary. For example, you can create a power waveform such as power supply dips, instantaneous interruptions, and voltage fluctuations to use in an immunity test (to cause malfunctions in equipment caused by power supply harmonics).
