5.1.4. Background recording
In background recording mode the SB records the peak values within a given time window. Please
note that event recording is not affected by the peak recording – both services may run
simultaneously.
In the field Mode you choose what kind of peaks should be recorded:
Peak is the maximum value of the signal during each period (as defined below).
Peak + Vector Sum includes the maximum of the vector sum of the 3 channels
Peak + Dominant Frequency includes the dominant frequency for each period
Peak + Vector Sum + Dominant Frequency includes the vector sum and the dominant
frequency for each period
You have to set-up the Period and the total Duration of a file. For verification purposes, the SB
shows the number of periods in one file of the given duration as Number of samples in file.
