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.

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.
The MR8847A performs multichannel measurement with simultaneous,
high-speed sampling of all channels at 20 MS/s.(resolution: 50 nsec)
High-speed sampling allows you to measure the rising edge of pulses and detect anomaly operations
and instantaneous waveforms that occur suddenly with high precision.
Connections between analog input channels, and between the input channel and the main unit,
are isolated by isolation elements. So potential differences can be measured without any concerns,
just like with an oscilloscope.
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.
The included Waveform Creation Software SF8000 can be used not only to create waveforms,
but also to perform calculations such as adding noise and multiplying waveforms quickly and easily.
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.
Maximum rated voltage to ground is 1000 V for CAT III and 600 V for CAT IV environments.
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.
The Memory HiCorder now supports a wide variety of measurements with a total of 13 plug-in modules.
■ Inverter / UPS Test
- Operation testing and evaluation during load fluctuation
- Confirmation of UPS switching
■ Power Monitor and Logger
- Identify power fluctuations when power supply is turned ON/OFF and during load fluctuations
- Long-term fluctuations in power
■ Control Simulation
- Generate simulated output of each type of sensor signal
- Fluctuating simulated output for 12 V DC car batteries
■ Vibration / Endurance Tests
- Analyze the relationship between engine control and vibration
- Confirm equipment durability
Logic input of up to 64 channels
The MR8847A has 16 built-in logic input channels.
Add 3 logic input units to record a total of 64 channels at once.
You can also display the waveforms for all channels on a single screen—ideal for timing measurements.
Up to 10 channels of analog waveforms can be recorded at the same time for efficiency.
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.
X-Y RECORDER
Saving data in chronological order allows records to be saved as digital data,
rather than paper hardcopies that need to be stored.
Use pen up/down control to record only the required data.
The MR8847A can replaces mechanical pen recorders.
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.
The MR8847A also has a waveform judgment function for FFT analysis waveforms and X-Y waveforms built in.
Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
Number of channels
