Synchronous Averaging . Synchronous averaging, also sometimes redundantly called Time Synchronous averaging, was discussed earlier as a method of background noise reduction in spectra of complex signals. Now, we will look at it as a means of greatly increasing the information we can extract from the time domain vibration waveform.. Synchronous averaging

Data Sampling Time 2015 33 Data sampling time is the amount of time required to take one record or sample of data. It is dependent on the frequency span and the number of analyzer lines being used. T Sample = N lines / F span Using 400 lines with a 800 Hz frequency span

Vibration analysis what does it mean? By Chuck Yung Interpreting the vibration signature of plant equipment. Vibration analysis, properly done, allows the user to evaluate the condition of equipment and avoid failures. Maintenance personnel can minimize unplanned downtime by scheduling needed repairs during normal maintenance shutdowns. How
