Time Waveform Measurement Definitions
The Emonitor software and the Dynamic 2500 data collector support time
waveform measurement definitions. This topic lists the unique characteristics of
the Dynamix that you may need to know when setting up and collecting time
waveform data.
The Dynamix 2500 data collector cannot collect phase with time waveform
measurement definitions. You can choose to have the instrument collect a time
waveform only if a magnitude measurement at the same location is in alarm.
TIP
The Dynamic 2500 data collector supports integrated time waveform
measurements (single integration). This means you can collect a time waveform
with velocity units using an accelerometer or displacement units using a velocity
transducer.
The length of the time waveform depends on the maximum frequency you select
in the collection specification. You can calculate the number of time samples from
the number of spectral lines (Collection Specification dialog box) using this
formula.
time samples
You can calculate the total time required to collect a time waveform measurement
from the Number of lines value and the Maximum frequency value in the
Collection Specification dialog box (Setup > Collection Specification).
