Data Acquisition Analysis System
Wave Stocker
The system composed of Charge Amplifier
VM-1980/3, simultaneous sampling unit
VM-0330/16,data record software ” Wave Stocker”
This is the really useful equipment which our Solution Team
developed using their experience obtained at their customer’ s site.
Simultaneous measurement by with sampling of max.16 channels is possible, enabling easy waveform analysis. This can be used for versatile tasks as the measurement at the site, inspection and R & D.
Small size, light weight
Expandable up to 16 channels
High speed data transfer by Gigabit Ethernet
Voltage input enables data acquisition or analysis of any other data than vibration’s.
Simple operation trough user friendly interface
Long term continuous data acquisition is possible by the versatile logger function
Functions
Waveform Acquisition
The waveforms of up to 16 channels are displayed. Arbitrary data observation as of real time waveforms (sole),
FFT plots (sole) or waveform and FFT plot (dual) are possible during the measurement is proceeding.
Various setup operation as data acquisition, halt and stop etc, are possible to be made like the home video recorder.

| Analysis 000 Data Record Tool Concept : This is a tool for waveform data pre-processing. The real time sampling data out of 16ch A/D unit are filed. Data required for the function as of waveform monitoring, regeneration, analysis are outputted or filtered out. And original waveforms or FFT Analysis graphs for 16Ch are available. Measurements can be monitored in real time. This is an essential item to use other analysis tools. |
