Phase Normal / Phase Alternate
On the default Phase display plot, all phase values are plotted within a 360° range of +180° to –180°, with
0° in the center [wrapped phase]. This 360° range represents one complete cycle of delay at any given
frequency. You can also choose to view the phase within a 360° range of 0° to 360° (alternate phase). This
is useful if there is a reverse of signal polarity within your transfer function measurement setup. Please refer
to your analyzer documentation for further information regarding phase and the implementation of these
options.
18.4.4.10 Invert
Pressing the INVERT button swaps the inputs to the Transfer Function calculation, so the analyzer divides
the reference signal by the measurement signal. This feature is mainly used when you want to display the
inverse (upside‐down) magnitude response curve of an EQ or processor channel to facilitate using the room
or system response as a template for setting EQ lters.
