Acquisition Method:
Peak/Valley
The Peak/Valley Acquisition Method acquires data on dependent signals
when the software detects a peak or valley in the specified master signal. When
selected, the application:
• Permits only channel count signals to display on the x-axis (the signal list
on the X-Axis subtab of the Plot Setup tab will display only channel
count signals).
• Displays two traces per selected y-axis signal (selected on the Y1-Axis
and Y2-Axis subtabs of the Plot Setup tab); one displays peaks, the other
displays valleys.
• Selects logarithmic scaling on the x-axis by default. You can change the
scaling in the Properties window (right-click on the plot to access the
Properties window).
When you select the Peak/Valley Acquisition Method, you must define the
master signal and sensitivity.
Master Signal Selects a signal that determines when data is acquired.
Sensitivity 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.
