parameters, but considers all additional parameters concerning the frequency and
level.
Example parameters that affect the frequency and level:
●
Frequency offset
●
Multiplication factor
●
User correction
●
Digital attenuation
Any of these cases are indicated by a dedicated icon in the status bar, depending on
the affected parameter.
Figure 6-1 illustrates the calculation of the "Frequency" and "Level" values, displayed
in the status bar.
