Recorder for On-site Jobs and R&D
Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, acceleration and rotation due to complete isolation between channels and from each channel to the ground. The MR8847A delivers 20MS/s sampling, 16 isolated channels, and max. 1000V direct input, all housed in a tough and field-ready body to properly respond to the most challenging work sites from transformer substations to railway maintenance yards to paper and steel mills.

How to use the Hioki MR8847A Memory HiCorder to Generate Signals While Monitoring Waveforms
The Hioki MR8847A is function generator, arbitrary waveform generator, and waveform recorder all in a single device. Easily observe waveforms while changing the signal amplitude or frequency, programming a variety of waveforms to output in the desired order, and adjusting other testing conditions.
An extensive selection of 13 modules accommodates the full range of measurement applications
Hioki has added new high-performance modules in response to overwhelming demand.
High-speed 20MS/s, 16-channel, Fully Isolated Memory Recorder
The MR8847A performs multichannel measurement with simultaneous,
high-speed sampling of all channels at 20 MS/s.（resolution: 50 nsec）
Generate and record in a single unit / ARBITRARY WAVEFORM GENERATOR UNIT U8793
Just one Memory HiCorder gives you a function generator mode, arbitrary waveform generator mode, and waveform measurement mode. This makes it easy to observe waveforms while varying test conditions, such as changing the signal's amplitude and frequency and programming various waveforms to output in order.
Directly input high voltage without a differential probe / HIGH VOLTAGE UNIT U8974
Since you can directly input up to 1000 V DC and 700 V AC, a differential probe is no longer necessary.
Logic input of up to 64 channels
The MR8847A has 16 built-in logic input channels.
FFT analysis function
The MR8847A can perform one-signal FFT for analyzing frequency components, two-signal FFT for analyzing transfer functions, and octave analysis for acoustics.
Saving data in chronological order allows records to be saved as digital data, rather than paper hardcopies that need to be stored.
Determine waveform quality
Use the waveform judgment function, which monitors whether a waveform extends beyond the given area, to easily determine the quality of signal waveforms that are normally difficult to judge.
