Detalii produs Hioki – MEMORY HiCORDER MR8847A
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 20 MS/s sampling (*1), 32 isolated channels, and max. 1000 V 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.

High-speed 20MS/s (*1), 32-channel, Fully Isolated Memory Recorder
The MR8847A performs multichannel measurement with simultaneous, high-speed sampling of all channels at 20 MS/s (*1). (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.
*1: When U8975, U8977, U8978 are installed, max. sampling speed is 10 MS/s.
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.
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 20 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.
