If necessary, the generator signal can be automatically synchronized with the measurement time blocks by internal triggering, e.g. when using a shaker with a chirp signal.
Description
Various systems with different numbers of channels and varying maximum frequency ranges are available – from a small external USB box with 2, 4, 8, 12 or 16 channels for connection to a notebook to large measurement systems with 64 or more channels and an Ethernet interface.

Functions
Settings
All settings for vibration measurement such as frequency range and frequency resolution, voltage ranges, ICP supply of sensors, trigger and window functions are made using clear dialog windows and selection menus. All settings and display formats can be saved. A sensor database is available in the analyzer software to make setting up the measuring channels easier.
Analyzer
All graphic interface settings can be saved in files and assigned to the function keys. This allows the user to quickly switch between the different displays during the measurement.

Data recorder
By writing the measurement data directly to the hard disk, even multi-channel measurements can be recorded seamlessly over a very long period of time. For example, in triggered mode, the data recorder can record a specific event for a specified duration and then return to standby mode for further measurements.
Measurement database
Time and spectral data are saved as files and can be reloaded later for further processing and evaluated with the vAnalyzer software. The displayed graphs can be printed or saved as WMF files.
Export
All data stored in the vAnalyzer database can be exported as a UFF or ASCII file.
Modal interface
A direct interface to our modal analysis package vModal is integrated into the vAnalyzer. In addition, the measurement data can be made available to external software for further processing via a UFF export module.
Hardware
From notebooks with external USB measurement boxes and four measurement channels to industrial computers with 32 or more channels to front ends with very high channel counts – various system variants are available. Depending on the hardware, one or more generators and tachometer inputs are available. We create customized interfaces for your data acquisition systems upon request.
Generator output
The built-in generator can generate the following signals
- Sinus
- Noise
- Chirp
- Rectangular function
- Sweep
- Step Sinus
Report creation
All measurement curves can be exported as WMF files, copied to the clipboard or sent directly to the printer.
