Mastering Multi-Channel, High-Speed Measurement
In the demanding fields of electrical engineering, industrial automation, and research, the ability to accurately capture, analyze, and manage complex electrical signals is paramount. From evaluating power supply stability to dissecting the intricacies of motor control, engineers and technicians often face challenges that exceed the capabilities of conventional oscilloscopes. The need for a versatile, robust, and high-speed data acquisition system that can handle numerous channels simultaneously, while ensuring safety through isolation, is more critical than ever. This is precisely where advanced Memory HiCorders shine, offering comprehensive solutions for a wide range of measurement applications. The Hioki MR8847A, a standout in this category, is designed to revolutionize how you conduct your tests. It integrates cutting-edge technology to perform multi-channel, high-speed measurements, allowing for the precise capture of transient phenomena, long-term data logging, and complex signal analysis, thereby enabling a deeper understanding of system behavior and faster troubleshooting.
Extensive Modules for Diverse Applications
The Hioki MR8847A Memory HiCorder stands out due to its extensive modules for diverse applications, offering unparalleled adaptability. In response to overwhelming demand from various industries, Hioki has continuously expanded the capabilities of its Memory HiCorders. The MR8847A now supports a vast array of measurements with a total of 17 plug-in modules. This modularity is a game-changer, allowing users to configure the instrument precisely to their specific testing needs rather than being confined by a fixed set of inputs. For instance, in Inverter / UPS Test scenarios, it excels at operation testing and evaluation during load fluctuation and confirmation of UPS switching behavior. In Power Monitor and Logger applications, it’s ideal for identifying power fluctuations when power supply is turned ON/OFF and during load fluctuations, as well as tracking long-term fluctuations in power. For Control Simulation, it can generate simulated output of various sensor signals, including fluctuating simulated output for 12 V DC car batteries. Lastly, in Vibration / Endurance Tests, it helps to analyze the relationship between engine control and vibration and confirm equipment durability. This vast selection of modules ensures that the MR8847A can serve as a comprehensive, all-in-one solution for an extensive range of demanding measurement tasks across multiple industries.
High-Speed, Isolated Multi-Channel Sampling
The core of the Hioki MR8847A’s exceptional performance lies in its high-speed, isolated multi-channel sampling capabilities. This Memory HiCorder is engineered to perform multichannel measurement with simultaneous, high-speed sampling of all channels at an impressive 20 MS/s (with a resolution of 50 nsec). This blazing speed is critical for accurately capturing the fastest of signals, allowing users to precisely measure the rising edge of pulses and detect anomaly operations and instantaneous waveforms that occur suddenly with high precision. Such fleeting events are often the key to diagnosing intermittent faults or understanding complex system behaviors that slower instruments might miss entirely. Furthermore, a crucial safety and accuracy feature is its complete isolation: connections between analog input channels, and between each input channel and the main unit, are isolated by isolation elements. This design means that, unlike many oscilloscopes, potential differences can be measured without any concerns of damaging the instrument or the circuit under test, or introducing measurement inaccuracies due to ground loops. While some specific units like the U8975, U8977, and U8978 may have a maximum sampling speed of 10 MS/s, the overall capability for high-speed, isolated, multi-channel acquisition remains a significant advantage, ensuring safe and reliable capture of critical data in complex electrical environments.
Integrated Generation and Measurement Power
The Hioki MR8847A offers unparalleled efficiency through its integrated generation and measurement power, exemplified by the ARBITRARY WAVEFORM GENERATOR UNIT U8793. This single Memory HiCorder unit uniquely combines a function generator mode, an arbitrary waveform generator mode, and a waveform measurement mode. This integration is a game-changer for testing and troubleshooting, making it incredibly easy to observe waveforms while varying test conditions. For instance, engineers can effortlessly change a signal’s amplitude and frequency or program various waveforms to output in a specific sequence, and then immediately measure the system’s response using the same device. This eliminates the need for separate, synchronized instruments, significantly streamlining the test setup and execution. The accompanying Waveform Creation Software SF8000 further enhances this capability, allowing users to not only create complex waveforms but also to perform quick and easy calculations such, as adding noise to simulate real-world disturbances or multiplying waveforms for more intricate test scenarios. This combined generation and measurement capability within a single unit drastically improves workflow efficiency and accuracy, enabling comprehensive testing under controlled and varied conditions.
Direct High Voltage Input Capability
A standout safety and convenience feature of the Hioki MR8847A is its direct high voltage input capability, especially with the HIGH VOLTAGE UNIT U8974. This specialized unit allows for direct input of up to 1000 V DC and 700 V AC, completely eliminating the necessity for an external differential probe. Differential probes are often costly, cumbersome, and can introduce their own limitations in bandwidth or accuracy. By integrating this capability directly, the MR8847A simplifies the measurement setup, reduces potential sources of error, and enhances overall safety. The unit is built to robust safety standards, with a maximum rated voltage to ground of 1000 V for CAT III environments and 600 V for CAT IV environments. These ratings confirm its suitability for direct measurements in high-energy electrical installations, power distribution systems, and industrial machinery where high voltages are commonplace. This feature is particularly valuable for power electronics engineers who frequently work with high-voltage switching circuits, ensuring that they can accurately and safely capture high-amplitude waveforms without additional specialized equipment, streamlining their testing and analysis workflows.
Expansive Logic and Analog Channel Integration
The Hioki MR8847A provides expansive logic and analog channel integration, offering remarkable flexibility for complex system analysis. The base MR8847A unit comes with 16 built-in logic input channels, which are crucial for monitoring digital states, control signals, and timing relationships. For applications requiring even more digital inputs, users can add up to three additional logic input units to record a total of 64 channels at once. This massive channel count is invaluable for dissecting the intricate workings of microcontrollers, PLCs, and other digital control systems. Furthermore, the ability to display the waveforms for all channels on a single screen makes it an ideal tool for precise timing measurements, allowing engineers to visualize the exact sequence of digital events. Complementing this, the MR8847A can also record up to 20 channels of analog waveforms at the same time alongside the logic signals. This simultaneous capture of both analog and digital data is incredibly efficient, enabling comprehensive correlation analysis between control signals and their resulting analog responses, streamlining debugging and performance optimization in mixed-signal environments.
Advanced Analysis and Recording Functions
The Hioki MR8847A is equipped with advanced analysis and recording functions that significantly enhance its utility for in-depth signal characterization. Beyond basic waveform display, the MR8847A includes powerful FFT analysis functionality. It can perform one-signal FFT for analyzing frequency components, crucial for identifying harmonics, noise, and vibration frequencies. It also supports two-signal FFT for analyzing transfer functions, essential for characterizing system response and identifying resonant frequencies. Furthermore, it offers octave analysis for acoustics, making it a valuable tool in noise and vibration studies. Another innovative feature is its X-Y RECORDER capability, which allows for the digital saving of data that traditionally would require mechanical pen recorders. This means saving data in chronological order as digital data, eliminating the need for bulky paper hardcopies and simplifying data storage and retrieval. With pen up/down control, users can precisely record only the required data, ensuring efficient data logging. Finally, the waveform judgment function is a critical tool for quality control. It monitors whether a waveform extends beyond a predefined area, making it easy to determine the quality of signal waveforms that are otherwise difficult to judge visually. This judgment function is also built in for FFT analysis waveforms and X-Y waveforms, providing automated quality assurance across various measurement types.
