Peak/Valley Acquisition Process
About Peak/Valley Process
The Peak/Valley Acquisition process records the output of all selected signals
when the software detects a peak or valley in the master signal you specify.
When you define a Peak/Valley Acquisition process, you must define the master
signal, the sensitivity, the signals you will record data on, the data destination, the
buffer type, and the output units.
Sensitivity A sensitivity value specifies how much the master signal must change to detect a
peak or valley:
• Setting the sensitivity too low may cause signal noise to be recognized as
peaks and valleys.
• Setting the sensitivity too high may cause low amplitude signals to be
missed.
