Hioki 8861-50 Hi-Speed Memory Recorder
These models feature personal computer-like operability with mouse and keyboard support, accelerated by internal high-speed hardware that provides simpler, faster operation. The Memory function monitors fast waveforms as easily as an oscilloscope while the Logger function records trend graphs in real time. Convenience is improved by enhanced control via LAN and USB capabilities. A broad selection of plug-in front-end modules supports a wide variety of measurement objects. Abnormal phenomena are accurately captured with 20 MS/s sampling and 16-bit resolution on isolated inputs.![Hioki_8861-50_image_2]()
Memory Function for High-Speed Waveform Monitoring
Using the same operating principle as a digital oscilloscope, data is recorded to the expanded internal memory at high speed. Sampling rate is up to 20 MS/s (50-ns period) for all channels simultaneously. Capture unpredictable operating anomalies and transient waveforms.
Records to Solid-State Memory
Because instruments that rely on disk access such as hard disk drives are susceptible to vibration, they are often unsuitable for on-board measurements. MEMORY HiCORDERs are preferable for on-board testing because they write data to solid-state memory with no moving parts. You can back up data to a PC Card or USB storage device when finished measuring. When the optional memory backup unit is installed, the instrument’s internal memory data is preserved when power is turned off.
All Channels Isolated, 20 MS/s Sampling
Except when using the Scanner Module, every input channel has its own A/D converter. Because all channels are sampled simultaneously, transient waveforms can be easily observed along with signals. The Scanner Module switches all inputs through a single A/D converter, but even in that case, all channels are isolated.
External Sampling Input Capability
The sampling rate for memory recording can be synchronized to an external clock signal (up to 10 MS/s). So, for example, sampling can be synchronized to the rotation cycle of an engine.
Large Capacity Internal Memory
Both high-speed write capability and a large memory capacity are provided to support high-speed sampling. Total memory capacity ranges from 32 megawords to 1 gigaword, enabling capture of waveform peaks by high-speed sampling, as well as long-term recording and long-period waveform capture.
Internal Memory Division (Segmentation) Function
Internal memory can be segmented for use into 4,096 blocks. By using “sequential save” to write data to the segmented memory, the waveform in any block can be overlaid with that in a reference block for comparison.
