We have further increased the arithmetic processing speed and real-time analysis capacity to more than 16 times that of conventional models. An Ethernet LAN interface is used for high-speed connectivity.
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 users 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.
 
[[File:teamworkanalyzer.png|700px|cascade mode]]
 
=== Measure From Sound / Vibration and Strain Gauge / Temperature ===
(OR35 / TW OR36 / TW OR38 only)
[[File:Usersmanual_32.jpg|200px|right|Conditioner on analyzer|alt=Temperature and straing conditionner]]
By mounting a [[XPod_Bridge_-_Strain_gauge|strain gauge conditioner]] and [[NVGate_X-Pod:_Temperature_probe_conditioner|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)
<br>
<br>
<br>
<br>
 
===CAN-bus Module Available ===
[[File:Can_Bus.jpg|150px|right|Can bus measurement|alt=Can bus to add on OROS instrument]]
(OR10/ TW OR35 / TW OR36 / TW OR38 only)
 
By using the [[NVGate_Can_BUS|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.
<br>
<br>
 
===Recording is possible without the use of a PC by using the FFT analyzer in stand alone mode ===
(OR35 / TW OR36 / TW OR38 only)
 
[[File:d_rec.PNG|150px|right|Data acquisition recorder|alt=Vibration time signal Measurement without PC]]
The FFT analyzer is equipped with a [[NVGate_D-Rec|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.
 
<br>
<br>
<br>
<br>
 
 
 
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.
 
[[File:home3.PNG|800px|software ribbon|alt=NVgate ribbon technology]]
 
===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.
 
 
[[File:FFT_analyzer_spectrum.png|500px|FFT spectrum|alt=Parameters easy to change]]
 
===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 [[NVGate_Control_Panel|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.
 
[[File:control pannel_test.png|700px|Software FFT settings|alt=Control easily the software]]
 
===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 [[NVGate_Filter_Builder|filter]], it is possible to remove abnormal noise components from the recorded signal and perform processing such as reproducing the extracted abnormal noise components.
 
[[File:filter_fft.png|600px|Filter analyzer]]
 
===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.

=== Synchronous Measurement (Up to 1000 Channels) ===
(TW OR35 / OR36 / OR38 only)


High-precision synchronous measurements (0.2° @ 20kHz) are achieved by daisy-chaining analyzers with standard LAN cables. This setup is ideal for large-scale modal analysis or complex tracking measurements.

[[File:drag_drop_report.jpg|Software NVGate]]
 
===One-click report creation function===
 
 
Simply click the report button located on the ribbon interface to create a [[NVGate_Report|report]] file containing the current measurement results.
 
[[File:allwindows_.PNG|NVGate report|alt=report all windows]]
 
• The content of the report is customizable. Customize it to the format that best suits your needs.
 
[[File:report-customize.jpg|500px|customize FFT analyzer software report|alt=Post analysis vibration software]]
 
===Measurement data search function===
[[File:pc cloud.PNG|right|Data stored|alt=cloud vibration data]]
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:

===Fail judgment function as standard===
The [https://youtu.be/kx2HbcvfG_w 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.
 
[[File:fail_test.JPG|Pass/fail test on resonnance frequency impact hammer test|alt=Failed pass test on resonnance frequency test]]
 
===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.

*'''Monitoring of wind power generation equipment and abnormality diagnosis'''
 
[[File:eolienne.PNG|left|Monitoring vibration]]
 
Measuring vibration noise generated from rotating machines (gearboxes, generators, etc.) in wind power generation equipment is indispensable for equipment maintenance and longevity. In addition to the real-time analysis capability of rotating machinery, which is the strength of the OROS FFT analyzer, remote control / monitoring and stand-alone functions can be used to more efficiently diagnose equipment for wind power generation equipment.

*'''Diesel engine camshaft rotational twist measurement'''
[[File:danielson torsionnal.PNG|left|Diesel engine camshaft rotational twist]]
 
In the prototype of a small diesel engine, there is a problem that the rotational torsional vibration of the timing belt and the camshaft resonates, causing a large vibration. By measuring rotational fluctuations and rotational twists with high accuracy using the six tachometer channels mounted on the OROS FFT analyzer, it is clarified which rotational order is dominant for vibration.<br>
