## Powerful Data Analysis Capabilities 

## **FFT Analysis Function** 

## **Simultaneously measure four phenomena** 

The MR8875's FFT analysis function can simultaneously analyze four phenomena with a single measurement. 

By performing FFT analysis of different signal inputs from channels 1 through 4, it is possible to analyze the frequency components of each channel occurring at the same time. For example, you can simultaneously view the linear spectrum, RMS spectrum, power spectrum, and phase spectrum for a signal input to channel 1. 

## **Analysis functionality for a variety of measurement scenarios** 

The MR8875 features calculation functions that are often used during field measurements. The linear spectrum is used in analysis that focuses on waveform amplitude values, while the power spectrum is used in analysis that focuses on energy, for example noise and vibration measurement. You can select the calculation function that best suits your application—for example, use a transfer function for measurement that identifies internal systems based on I/O characteristics. 

## **Peak value display function (marker display)** 

The peak value display function can be used to search for maximum and local maximum values and then display them. Characteristic values can be easily displayed even without using a cursor.  Since the MR8875 stores up to 200 frames (200 calculation results) of data, it will automatically search for the peak value again if a different frame is selected. 

## **Running the spectrum display function** 

The MR8875's running spectrum display function can be used to continuously display spectra that change over time. Up to 200 frames* of the most recent calculation results can be stored. Although Hioki's MR8847 Series only supports running the spectrum display for certain types of calculations, the MR8875 can generate this display with all FFT calculation functions. Additionally, if the selected frame is changed, the cursor value can also be loaded. 

_* Frame data is stored in the instrument's internal memory, regardless of whether the running spectrum display is used._ 

The MR8875 can also freeze the spectrum display on its screen during measurement. This function allows data to be observed without the inclusion of unneeded information on the screen or in the data. All calculation results can be output as CSV data, which can be loaded into a spreadsheet application such as Microsoft Excel and used to create a three-dimensional graph.

Example of data displayed with Microsoft Excel<br>**----- End of picture text -----**<br>

**Extensive window functions** 

The MR8875 provides a total of seven window functions, including rectangular and Hanning variants. The rectangular function is used for analysis that focuses on spectrum amplitude values, while the Hanning function is used for analysis that focuses on the degree of spectral separation of frequency components. Additionally, by using an exponential window in impact measurement utilizing an impulse hammer, the instrument enables more precise analysis by limiting unneeded noise components on the time axis. 

## **Continuous calculation function** 

When analyzing a signal that changes over time, the number of FFT calculation points becomes a limitation, preventing the waveform from being analyzed in all time domains. Furthermore, using too many FFT points prevents the desired results from being obtained because the spectrum is averaged. The MR8875 resolves Number of skips these problems with its continuous calculation function. For data covering extended periods of time, calculation Time waveform points can be shifted by a number of skip points* at a uniform interval. Moreover, calculations for up to 200 frames can be accomplished with a single operation. CalculaFFT calculation tion results for different time periods can be reviewed by results Frame 2 Frame 200 changing the calculation frame, regardless of whether Frame 1 you're using the running spectrum display or a singleIllustration of continuous calculation screen display. 

_* The number of skip points can be set from 100 to 10,000._ 

## **Overlay display function** 

The MR8875's overlay display function can be used to observe variations in waveforms captured using continuous measurement over time. Although previous Hioki models have not been able to overlay FFT calculations, the MR8875 offers this capability, improving the visibility of analysis. 

## **Visually appealing screen displays** 

The MR8875's display can be switched according to the application at hand. For example, its single-screen display can be used when focusing on the correlation between channels, while its four-screen display can be used to isolate complex spectra for viewing. Additionally, time and spectrum waveforms can be displayed above and below one another when focusing on correlation with a captured time waveform.

## **Waveform Calculation Function** 

## **- - Real time inter channel calculation** 

The MR8875 features a new real-time inter-channel calculation* function that allows you to observe and record results for up to two calculations on the same input module while measurement  continues. 

- _Between channels on the same input module only (supported input modules: MR8901/8902/8903)_ 

- _Calculations between different user-set phenomena on the MR8902/8903 (voltage and temperature, etc.) are not supported._ 

## **Waveform-dimension calculations** 

The previous MR8875 firmware version only supported calculations that generated values such as averages and RMS values, but the new version can process for up to eight calculations simultaneously, including arithmetic operations as well as differential-integral and other waveform-dimension calculations. 

## **Digital filter calculations** 

The MR8875 offers new digital filter calculations* as part of its selection of waveform processing calculations, allowing the necessary bandwidth portion of a waveform containing noise to be calculated and the resulting waveform displayed. 

_* Finite impulse response (FIR) and infinite impulse response (IIR) digital filters are offered. Both of the digital filters can be configured with an LPF (passing only the low-frequency component), HPF (passing only the high-frequency component), BPF (passing only a frequency bandwidth of a certain width), or BEF (rejecting only a frequency bandwidth of a certain width)._

- _Although FIR calculation processing is time-consuming, it can yield waveforms with no phase distortion. By contrast, IIR calculation yields results at a relatively faster calculation speed but is prone to phase distortion. Each filter’s cutoff frequency is user-specified._

You can acquire CAN data and analog data in a non-contact method by p ~~a~~ iring the SP7001-95 with the MR8875 and MR8904. 

n **Graph CAN signal information and analog data simultaneously** 

**Captured CAN data Display of waveforms on Measured analog data same time axis** 

The MR8875 displays an analog waveform that is converted from a CAN transmission in real time. On the waveform, analog data such as voltage, temperature, strain, and information collected from the CAN bus such as vehicle speed and RPM can be shown simultaneously.

## **Vector’s CAN database can be loaded using supplied software** 

Industry standard CANdb® database files can be loaded onto the supplied setting software to identify the CAN channel signals. CAN messages can be viewed using the customer-specified message and signal names, as well as scaled engineering units. Since parameters such as signal data type, start bit, length, and byte sequence are all pre-defined in CANdb files, users can concentrate on their measurement tasks without needing to define signals.

## **Withstand extreme environmental tempe** ~~**r**~~ **atures, vibrations, and data loss threats due to power** ~~**ou**~~ **tages** 

In road tests, extreme environmental conditions associated with temperature and vibration are traditionally hard on measuring instruments. The **MR8875** has the wide operating temperature range of -10˚C to 50˚C (14˚F to 122˚F) and is co ~~mplia~~ nt with the stringent Japanese standard for vibration resistance performance used in automotive testing (JIS DI1601). It is designed to withstand the harsh conditions of in-vehicle measurement. 

In the event of a power outage while data is being recorded, the power supply is maintained using a built-in large-capacity capacitor until data is completely written to the SD or USB memory.  Risk of data loss or damage to the file system is minimized, and after power is restored, measurement can be restarted automatically.

## n **Maximum time to record to the internal storage memory** 

* The MR8875 is able to save up to 16 channels of data per module. The graph below shows 16 channels because it is looking at storage per unit. However all units in use will follow the same maximum recording time. 

* Built-in logic, and pulses P1 and P2 each use the capacity equivalent to one analog channel.
