This is a license-free viewer function that anyone can use.

By providing files containing measurement data and analysis results saved in O-Solution to relevant parties, data can be easily shared using O-Solution Lite.

By using O-Solution Lite and DS-5000 (data station), it can be used as a "data logger".

Anyone can download it and start using it right away.

This software allows you to freely edit and analyze large volumes of time-series data. By adding optional functions, you can obtain a variety of analytical results.

Two simultaneous analyses are possible while recording.

*The following combinations cannot be analyzed simultaneously.
・Octave + Tracking + REC

You can freely "simultaneously display, arrange, and overlap" data with different physical quantities (vibration, rotational speed, torque, temperature, etc.), formats, and sampling frequencies.

Oscope has been used to compare multiple time series data when checking data on measurement control benches in automotive development. With O-Solution, you can import the huge amount of measurement data in an Oscope project directly into O-Solution (only time series waveform restoration is supported).

You can choose to copy time-series data files to the project file or reference them without copying. Referenceing them reduces file import time and the size of the project file.

For a 96-channel file with a recording time of 10 minutes:

*Only applies to orfx files.
*If the path of the referenced file changes, you will need to import it again.

Optional software is available to support a variety of applications.

This function allows you to quickly identify the frequency band causing unusual noises or vibrations by applying IIR or FIR filters to the recorded data and listening to it. It can also generate new time-series data with the filters applied.
It can filter both the order and frequency simultaneously, making it useful for investigating abnormal noises in rotating machinery.

FIR Filter

IIR Filter

This is the most basic function used to observe vibrations, sound intensity, and resonance phenomena in detail by decomposing a time-domain waveform into its frequency components. It can calculate power spectra, frequency response functions, coherence functions, and more.
In addition to FFT analysis, octave analysis and tracking analysis can also be measured in real time.
*Simultaneous measurement requires the tracking analysis function (OS-0523) and the octave analysis function (OS-0524).

It can display a tripartite graph ^*1, allowing you to simultaneously read frequency (Hz) and three amplitude values (acceleration (m/ ^s²), velocity (m/s²), and displacement (m)) in real time. This is convenient for evaluating floor vibrations when installing precision equipment.

By displaying the VC curve ^*2, you can quickly determine the permissible vibration standards and installation environment evaluation for vibration-sensitive precision equipment such as semiconductor manufacturing equipment, AFM (atomic force microscope), electron microscope, and laser interferometer.

*1 A tripartite graph is a graph that allows you to simultaneously read the amplitude of acceleration (m/ ^s²) and displacement (m) on the frequency (Hz) axis, with velocity (m/s) as the basis.

*2 VC curves (Vibration Criterion Curves) are the vibration tolerance reference lines for floors where precision equipment such as semiconductor manufacturing equipment and electron microscopes are installed. They are proposed as a standard for the micro-vibrations that can be tolerated when installing precision machinery. When using VC curves, evaluation is performed in a 1/3 octave bandwidth, and the standard is divided into 7 stages (VC-A, VC-B, VC-C, VC-D, VC-E, VC-F, VC-G) in 6 dB increments, and is divided into guidelines for applications ranging from optical microscopes to laser devices with long optical path lengths.

This function identifies the rotational speeds at which each order component of sound and vibration generated by rotating bodies such as motors and generators becomes amplified. In addition to constant ratio and constant amplitude tracking analysis, offset tracking is also possible.
Tracking analysis and FFT analysis can be measured in real time simultaneously.
* Simultaneous measurement requires the FFT analysis function (OS-0522).

Tracking analysis data can be created by combining multiple data points measured at constant rotational speeds (rotational speed-based data integration). Even without sweep operation, sequential measurements at constant rotational speeds allow for efficient identification of problematic orders within the rotational speed range.

The human ear has a logarithmic (Log) characteristic with respect to frequency, and octave analysis is well-suited to this characteristic. It is often used when determining noise levels, vibration levels, etc., and for measurements in accordance with ISO and JIS standards.
The multi-analysis function allows you to simultaneously measure FFT analysis and octave analysis.
In measurement mode (real-time measurement), octave analysis is possible for 1/1, 1/3, 1/6, 1/12, 1/16, and 1/24.

While general noise levels vary depending on the distance to the noise source and the test environment, sound power levels are uniquely determined in relation to the noise source. Therefore, it is a global indicator used in environmental labels (Eco Mark, Blue Angel) and noise regulations. Measurement methods are defined by international standards. The O-Solution DS-5000 enables efficient noise control by allowing measurement in accordance with standards and easy identification of sound sources and frequency peaks.

The measurement of radiated sound from computers, printers, and multifunction devices is defined by the specific standard ISO 7779. This specific standard is referenced when obtaining environmental labels. In addition to sound power levels, radiated sound pressure levels at the operator's or bystander's position, and significant discrete sound are calculated as needed.

Generally, sound countermeasures and evaluations for equipment are based on sound pressure levels, FFT analysis, 1/3 octave analysis, and other methods.
However, such analyses do not take into account the characteristics of human hearing, and the same results may result in different listening impressions.
Furthermore, when people hear sounds, they experience various sensations related to the sound, such as "loudness," "sharpness," and "roughness."
The OS-0525 sound quality evaluation function allows you to obtain sound quality evaluation indicators that take into account human auditory characteristics and correspond to various perceptions of sound, such as "loudness," "sharpness," "roughness," "variability intensity," and "tonality."

There are many sounds in the world that are bothersome even if they aren't particularly loud. Examples include the occasional rattling or buzzing sounds from interior components heard while driving, or the buzzing noise mixed in with the rotation of small motors. Sounds with significant temporal fluctuations are often irritating even if their volume (level) isn't very high. The OS-0526 variable sound analysis function can extract only the components with large temporal fluctuations, regardless of level, allowing for the quantification of various temporal fluctuation characteristics that were difficult to detect with roughness or fluctuation intensity alone. It also includes a function to compare sounds with and without fluctuations. (Variable Sound Simulator)

It can evaluate transient phenomena that are difficult to capture with FFT analysis. It can clearly display the time changes of frequency components while maintaining the frequency resolution of the characteristic quantities (frequency). It is equipped with short-time Fourier transform and wavelet transform.

Various statistical analyses can be performed in one window, such as calculating correlation coefficients by performing bivariate analysis of command values and feedback values.

Video files recorded with video cameras or smartphones can be imported into O-Solution and played back along with analysis results such as sound and vibration. By displaying the video alongside time-series data and FFT analysis results, it helps in understanding the phenomena of problematic parts in the movement of the object.
Since it can also analyze audio data from smartphones, it can be used, for example, to analyze the frequency of video files sent by field workers.

*Audio data obtained from a smartphone cannot be calibrated or converted to accurate decibel (dB) values unless calibration data is available. Please treat amplitude values as reference values only.

AVI files / MP4 files / MOV files / WMV files / M4A files

*Video data can be rotated vertically or horizontally (fine adjustments are also possible) for display.
* If the start positions of the data recorded with the DS-5000 and the video data are misaligned, you can use the time series alignment function to align the positions of each data.
*For details on supported codecs, specification Please check.

External control demonstration

Time series data can be acquired in real time from the DS-5000 hardware without going through O-Solution.
If you are interested, please contact us.

By using the hardware connection function (OS-0512), you can connect to the DS-5000 and use the FFT analysis function, tracking analysis function, and octave analysis function in measurement mode.

The DS-5000 series data station can be connected to a personal computer that meets the following specifications (specification conditions).

*The minimum required specifications are those that allow recording and measurement of up to 18 channels. When measuring a large number of channels, be sure to use a personal computer that meets the recommended specifications.

The stacked structure allows for unit configurations tailored to specific applications. A single unit can measure up to 48 channels. Up to five units can be connected to achieve multi-channel measurement.

The DS-5000 series data station is a modular measurement system that allows you to configure a measurement system tailored to your application and purpose by adding various units such as inputs, signal outputs, and batteries to the basic DS-5100 main unit in the required quantities.

By utilizing connections between units, you can temporarily build a multi-channel measurement system, allowing you to make effective use of your existing assets.
Up to five units can be connected.

When a measurement analysis that requires multiple channels suddenly occurs, the DS-5000 units that are usually placed in each laboratory can be connected to each other to create a multi-channel measurement analysis system.

The sounds and vibrations generated when closing a door are transient phenomena and cannot be reproduced. Inter-chassis connection is effective when simultaneous measurement of transient phenomena is required. With 48 channels per chassis, it is possible to connect up to 5 chassis to achieve a maximum of 240 channels of measurement.

*The above configuration is a "6ch FFT set."

*The above is an example.

The VW-3100 Portable Vibration Meter allows you to record while taking measurements and performing inspections on-site. Upon returning to the office, you can import the recorded data into O-Solution, allowing you to listen to the sound with filters applied and identify the cause of anomalies using FFT analysis.

*The above configuration is a "6ch tracking set."

As automotive parts manufacturers increasingly electrify their components, they are taking measures to prevent unpleasant noises by intentionally changing the inverter's carrier frequency to avoid areas where the component's natural frequency and order components are high. Offset tracking analysis is a method of analyzing the order ratio by tracking the changes in carrier frequency in response to this rotation.

*Required for measurements using a vibrator.

*If you have the viewer function of O-Solution Lite, you can record on-site without needing a license.

*This is necessary when using a vibrator for measurements, as shown in the example on the right.
*To perform modal analysis and operational analysis, the experimental modal analysis system software ME'scope is required. ME'scope is a product of System Plus Co., Ltd.

An IMU (Inertial Measurement Unit) is connected to the GPS speedometer to synchronously measure vehicle speed and vehicle behavior.
It can be used to evaluate vehicle dynamics and ride comfort, which are gaining attention due to the spread of autonomous driving.

We perform real-world NV testing using a combination of an FFT analyzer and a GPS speedometer.
The digital output of the LC-8300A is input to the DS-5000 to trigger synchronous recording. By using the LC-8300A's extensive functions to automatically start and stop recording, tests can be performed with good reproducibility.
