Data Acquisition and Real-time Analysis
Complete time domain and frequency domain analysis, including auto and cross power spectrum, auto and cross correlation, FFT, FRF, CPB, PDF, CDF coherence and histogram results etc., which meet your requirements for the real-time analysis. Sampling rate up to 192 KHz covers the frequency band for vibration and noise testing. Up to 12,800 lines of analysis spectrums, together with averaging, windowing, overlapping and triggering make your work more precise and efficient. Meanwhile, you may review your test output using multiple plots, such as orbit, polar coordinates and waterfall plots.
Data Recording, Playback and Offline Analysis
AVANT provides over 8MB /sec throughout rate based on USB 2.0 connectivity to any PC. It can record and transmit all channels’ raw data rapidly and continuously to an USB equipped PC. When you are back to your office or lab, you can playback the data in PC hard disk and take further analysis as well as on-site analysis.
Modal Analysis
This feature is tailored for both impact hammer and shaker excitation. With flexible triggering and a graphically adjustable Force/Exponential window function, it is easy to set up and acquire data by using an impact hammer. For shaker excitation, in order to get best FRF estimation, we not only provide a variety of source waveforms, including swept sine, white noise, burst-random and chirp and provide optimal signals, but also various FRF estimation methods according to different noise modes, to make best FRF measurements possible. Moreover, this functional module supports various file formats to save data, which are compliable with popular modal analysis software.
Acoustics Analysis
Sound generation and media are closely related to mechanical vibration. Acoustic analysis offers sound pressure and sound power analysis from field to lab. It provides 1/n octave filter functions compliant with ANSI S1.11-2004 criterion, and A, B, C, D or linear weighting are available. The measurement range is from 35dB to 145dB.
Shock Measuring
Work pieces are subject to various transient shocks or impact in the machining, transportation and actual use, which may cause damages to the product structure and performance, and even lead to failure. With our high performance sampling techniques to provide precise capture of transient waveform, you may capture the shock pulses easily and simultaneously when shock or impact event happens. On the other hand, you may define your own standard to analyze uncertain impact events.
Machine Diagnostics
AVANT can help you rapidly and easily isolate and diagnose vibration and noise problems in rotating machinery, using available waterfalls and spectrograms analysis. An advanced digital re-sampling method provides better tracking performance when the RPM varies rapidly. The order range is up to 320 orders, with order resolution as fine as 1/32 of an order.
Waveform Source
This module generates multiple types of wave sources to excite external equipments. It can generate sine, square wave, triangle wave, impulse chain, burst chirp, white noise, and pseudo-random, pink random and swept sine. You can set amplitude and frequency range of for each of them.
