Statistics

In the Info / Statistics section measurements are evaluated and values can be exported.

Configuration

By the Select menu the desired parameters are to be selected. In addition statistical values can be calculated from these parameters.

The results are displayed by the Info window immediately. In there, under dBref the reference value for dB quantities is to be defined. If power is evaluated, these values refer to the load impedance specified for the respective channel inside the Info window. The display of load impedances is to be switched on also by the Select menu; these values can be edited directly inside the table. The input related impedances managed here by the Info window are independent from the output related load impedances from the frontend menu.

Region defines the section to be evaluated.

If fractional octave filtering has been performed in advance, the selected parameters can be displayed band-wise. The assignment to the original channels is deposited in the channel tag. The nominal and the exact band centre frequencies can be displayed in the table. The following example shows a 4 channel microphone signal containing motor noise, filtered in 8 octaves for further evaluation:

By selecting Channel tag, fm nom., Crest and Leq the Info window produces the following output:
