4.5 Data Acquisition Parameters
There are several parameters to set in order to catch vibration signals without any
aliasing or resource wasting.
Sampling Rate
The speed to acquire the vibration, the unit is S/s which stands for samples per sec -
ond.
Section Length
Number of samples to be retrieved in each iteration cycle.
Cycle Count
Number of iteration cycles to be made in each trigger. Figure 4.8 describes the reac -
tion when section count is set to a non-zero value.
Figure 4.8 Trigger and Cycle Count
If the section count is set to 0, this would act as continuous mode. Each cycle would
be started right after previous cycle until stop trigger happens. In this mode, the trig -
ger would act as a gate to control the iteration. See Figure 4.9.
