This is where the concept of a Memory HiCorder truly shines, offering a distinct advantage. The Hioki Memory HiCorder MR8827 embodies this next generation of measurement instruments. It is designed to tackle a wide array of measurement tasks by seamlessly integrating high-speed sampling, fully isolated inputs across all channels, and the flexibility to record a mixed variety of analog and logic signals simultaneously. This comprehensive capability makes it an indispensable tool for engineers and technicians seeking a deeper understanding of complex system behaviors and efficient troubleshooting in demanding environments.

 

High-Speed, Fully Isolated Input Excellence

 

The foundational strength of the Memory HiCorder MR8827 lies in its high-speed, fully isolated input excellence. This device achieves an impressive maximum sampling speed of 20 MS/s on all channels, providing a fine resolution of 50 nanoseconds. This speed is crucial for capturing rapid transient events, fast-rising pulses, and other momentary phenomena that are critical for accurate analysis in dynamic systems. What truly differentiates the MR8827 from typical oscilloscopes is its complete isolation for the input of each channel, and between each channel and the main frame. This means that unlike oscilloscopes which often share a common ground reference, the MR8827 provides isolated input between the main unit and each channel, or between channels. This design eliminates concerns related to potential differences between measurement points, ensuring safe circuit connections even in high-voltage environments, such as during transformer interruption tests. This galvanic isolation is vital for preventing ground loops, ensuring measurement accuracy, and, most importantly, protecting both the instrument and the user when dealing with complex electrical systems where different voltage potentials are present, providing unparalleled safety and reliability in critical measurements.

 

Mixed Multi-Channel Input Versatility

 

The Memory HiCorder MR8827 offers remarkable mixed multi-channel input versatility, making it highly adaptable to diverse testing scenarios. This instrument can connect a maximum of 16 modules on its rear side, allowing users to combine various types of modules to accommodate inputs from a multitude of circuit types. This modularity means you can configure the HiCorder precisely for your specific application, whether it involves a mix of voltage, current, temperature, or digital signals. Beyond analog inputs, the MR8827 has 16 built-in logic input channels in the main unit. For applications requiring even more digital monitoring, the use of two Logic Unit 8973 modules can add an additional 8 connections each, supporting an impressive total of 64 channels for logic signal input. While expanding logic channels does reduce the number of available analog channels to 28, this flexibility ensures that the instrument can scale to meet complex digital monitoring needs while still providing substantial analog capability. This ability to mix and match analog and logic inputs across numerous channels makes the MR8827 an incredibly powerful tool for analyzing complex system interactions, such as correlating control signals with analog responses in sophisticated mechatronic systems.
