calibrated time signal. So, any wave files not recorded with the Opus Data Logger system will not be
calibrated (the Change Input Set-up function can be used to calibrate the signal, see section 10.1.7
for more details).
9.1 Analysis Functions Tab
The post-processing module includes six analysis functions, which are applied on the entire selected
framework (see section 10.3 for more information about the framework selection). These functions
are grouped under the Analysis Tab at the bottom of the main post-processing interface.
The next sections describe these functions in detail.
9.1.1 Global Historic
This function allows building the global level historic with an adjustable time resolution for the
selected channel. The global level calculation is done with power spectra using blocks with a number
of samples adjusted to match the requested time step. The power spectrum approach is used to
facilitate the A weighting and integration options. The interface of the Global Historic function is
presented in the next figure.
