Trigger during capturing and search after capturing

The trigger function allows you to set diverse parameters to detect a particular waveform anomaly during capturing. Setting the pre-trigger mode allows you to monitor the pre-trigger waveform. This is useful for analzying the cause of the anomaly. On the other hand, the search function allows you to detect an anomaly after all data is captured. This allows you to search for and display an anomaly in the same manner as with the trigger function. When a waveform is unpredicatable and setting a parameter during measurement is difficult, it is recommended to use the search function to locate an anomaly after capturing.

FFT analysis function

The single channel FFT function is used in spectrum analysis. The two-channel FFT function analyzes transfer functions. The octave analysis function is used in acoustic analysis. The singnal source for FFT analysis is a section obtained from the waveforms captured in the MEM function (the required number of pieces of data for FFT analysis are 1000, 2000, 5000, and 10000 is about ten times faster than with the conventional 8855 model.

Unlike the Hioki 8855 and 8841 models that support only the three window function options “Rectangular,” “Hanning,” and “Exponential,” the 8860 and 8861 models include four additional options, thus enabling you to select a window function from a total of seven options and up to eight simultaneous FFT calculations for analysis. Furthermore, the analysis channel can be selected independently.. Furthermore, a difference in calculation results of line spectrum between other companies’ FFT analyzers and HIOKI’s analyzer can be compensated by selecting the energy attenuation compensation method when using a window function.

Perform FFT calculation on the waveform from the MEM function

When performing FFT analysis on the data obtained by measurement with the MEM function, you can use the jog shuttle to specify an analysis point and view the calculation results on the same screen. Unlike with the conventional 8855 and 8841 models, you do not need to switch between the MEM function and FFT function screens to set the starting point of calculation. Furthermore, the display of “Raw Data” obtained by measurement with the MEM function and the calculation results of “Storage Waveform” on the same screen allows you to view the effect of the window function and the spectrum waveform on the same window, thus greatly enhancing operability for analysis.

High-speed data storage in ample internal memory

The 8860/8861 offers high-speed sampling of the input signal and storing of data in memory that is electrically isolated from the input. With the new dual sampling (2-axis sampling) feature, data logged with the SCANNER UNIT 8958 can be carried out at relatively low sampling rates while high-speed sampling using the 20MS/s analog units is simultaneously conducted. Display both measurement results on the same time axis. The sampling rate for the memory recorder can be controlled by the timing of an external clock signal (10 MS/s). This is useful for example to collect data synchronized to the running cycle of an engine.

The memory Boards (the 9715 series) offers up to 1 Gigaword. You have the option of choosing from the following memory boards for factory pre-installation - one board for Model 8860, and two of the same capacity for the 8861.
