The OROS series multi-function FFT analyzer is PC-based, high-performance, high reliability and easy to operate.
We have further increased the arithmetic processing speed and increased the real-time analysis capacity to more than 16 times that of the conventional model (OR20 series). An ethernet LAN cable is used as the interface.
In addition, the number of simultaneous recording channels in the frequency range (40 kHz) has been expanded to a maximum of 1000 channels and the dynamic range has been improved to 140 dB. These improvements allow a user to measure time signals over a wide frequency range simultaneously on multiple channels.

Synchronous Measurement Of Up To 1000 Channels is Possible by Combining Multiple Analyzers
(TW OR35 / TW OR36 / TW OR38 only)
High-precision synchronous measurements (0.2 ° @ 20kHz) are possible by simply connecting each analyzer using a general-purpose LAN cable. Function measurements can be taken with the hammer connected to the third unit in the chain and the accelerometers connected to each unit. Tracking analysis can be completed with the accelerometers connected to each unit while using a tachometer connected to the second unit in the chain.
Measure From Sound / Vibration and Strain Gauge / Temperature
(OR35 / TW OR36 / TW OR38 only)
By mounting a strain gauge conditioner and thermocouple conditioner on the Oros FFT analyzer, it is possible to measure strain and temperature data in addition to sound and vibration data.
Thermocouple amplifier: Supports types J, K, T, N, E (with temperature compensation)
CAN-bus Module Available
(OR10/ TW OR35 / TW OR36 / TW OR38 only)
By using the CAN-bus module, tracking analysis can be performed using information such as the engine speed flowing from the CAN-bus. By using this function, tracking analysis can be performed without using a tachometer.
Recording is possible without the use of a PC by using the FFT analyzer in stand alone mode
(OR35 / TW OR36 / TW OR38 only)
The FFT analyzer is equipped with a record-only button. Simply select a predefined measurement setup and press the record button to record onto the FFT analyzer alone without the use of a PC.
In addition, the back of the Fast Fourier Transform Spectrum Analyzer Multipurpose is equipped with an audio terminal and power supply. It is possible to record audio data while also measuring the time signal. The analyzer also can supply power to required sensors, such as proximity probes, tachometers and DC sensors.
Software Introduction
- Easy-to-use interface
- Real-time measurement / post-analysis can be performed with the same software platform (NVGate)
- One-click report creation function
Start the Measurement Quickly and Easily
You can start measuring immediately by using the quick function provided in the OROS FFT analyzer mult function. This is completed by defining the number of input channels in the channel field and the measurement/analysis content in the show results area.
The Oros series FFT spectrum analyzer multifunction uses an interface similar to the ribbon interface used by Microsoft Office. All menus are accessible via the ribbon interface, making it easy to change measurement settings.
One-click Setting Function
With the Oros series multi-purpose FFT analyzer, you can display related measurement condition settings by double-clicking on the measurement screen. For example, if you double-click on the FFT analysis screen, the dialog for setting the measurement conditions for FFT analysis will be displayed on the screen as shown below.
Control Panel
In addition, the OROS FFT spectrum analyzer is equipped with a control panel function that allows users to save frequently used measurement settings for quick access. By using this function, all settings can be changed on the control panel. For example, the following is the setting screen for a hammer test. By saving the input settings, threshold settings, and FFT analysis settings to the control panel as shown below, it is possible to make all the necessary settings quickly by only using the control panel.
Various filters can be applied to recorded signals & FFT analysis results
Four types of filters: Low-pass filter, high-pass filter, band-bus filter, and band-stop filter, can be applied to the results of recorded signal and FFT analysis. By using a filter, it is possible to remove abnormal noise components from the recorded signal and perform processing such as reproducing the extracted abnormal noise components.
Extract arbitrary order components from the color spectrum graph in real time
Any order component can be extracted in real time from the color spectrum graph.
Easy-to-read Layout
The area for arranging windows is called a layout. The OROS multi function FFT analyzer can create up to 16 layouts per project. You can easily arrange your windows by using the layout function. And your windows will open the same way each time.
It is possible to display up to 32 screens in one layout.
Up to 512 windows (= 16 x 32) can be displayed.
Layout utilization example:
Layout 1: Record waveform, FFT analysis result, order ratio analysis result displayed
Layout 2: Display 3D frequency analysis results and 3D order ratio analysis results
Layout 3: Display 3D octave analyzer analysis results
Easy operation <Graph layout selection button>
You can easily arrange windows just by selecting the grid menu.
Batch copy of measurement data with one menu. Numerical data can be transferred to Excel all at once.
Data measured at different times can be overwritten by dragging which allows for easily comparing measurement data.
One-click report creation function
Simply click the report button located on the ribbon interface to create a report file containing the current measurement results.
• The content of the report is customizable. Customize it to the format that best suits your needs.
Measurement data search function
Various information (meta-data) can be added when saving measurement data. You then can search for measurement data and projects based on the added information.
Filter:
- Project name
- Measurement date and time
- Measurement conditions
- Measurement target
- Measurement site
- User
Fail judgment function as standard
The pass / fail feature of NVGate can be performed automatically after setting the desired bounds.
In the example below, a dialog is displayed when the product fails, but it is also possible to output a contact signal instead of the dialog.
Automate post-analysis processing
The same processing can be continuously performed for record files measured multiple times. By using this function, it is possible to automate the generation of reports, and it is possible to generate the same number of post-analysis results and EXCEL-based reports as record files with one click. Processing that used to take more than a week can now be done in a few hours.
