Reliability & Durability Test and Measurements

Application

Measuring System

For waveform data acquisition and analysis

By simultaneous sampling measurement of up to 16 channels, data collection and judgement is possible.
It can be widely used for site measurement, monitoring and developmental study.

Features

High-speed simultaneous sampling of up to 16 channels is possible.

Real-time display of vibration waveforms and FFT

Continuous recording is possible.

Functions

Waveform acquisition

Waveforms of up to 16 channels are displayed and data observation (as waveform only, FFT only, waveform plus FFT) is possible during measurement is proceeding. You can operate various setup, halt and stop etc. instinctively just like a home video recorder.

Analysis function

Data is saved as text files after various analysis such as inter-channel calculation, filtering, waveform edit, FFT (spectrum) analysis, differentiation, integration, and DC removal etc.

System Composition

Data aquisition and analysis system (Wave Stocker) is composed of Simultaneous sampling unit (VM-0330R/16), Charge amplifier (VM-1980/3) and Data record software (DS-0330).

Analysis Tool

Function

Analysis 000 Data Recording Tool (standard)

Concept

This is a data saving tool to make a pre-processing as filing the simultanous sampling data from 16 ch A / D unit, waveform monitoring, regeneration, data extraction for analysis. It is also possible to monitor the original waveforms or FFT analysis in real time of 16 channels. This is an essential item to use other analysis tools.
