The Phase Display
The 764 Phase display is a Lissajous pattern display augmented with
a (phase) Correlation meter. It is designed for convenient, qualitative
monitoring of the phase relationship between any two input channels.
The Phase display always uses interpolated (4X “oversampled”) data,
even if interpolation is turned off in the level meters submenu. You
can set the instrument for either Soundstage or X–Y orientation of
the Lissajous pattern, as illustrated in Figure 21.
NOTE. The orientation of the Lissajous pattern, phase channel
pairings, and Correlation meter speed (see below) are selected
through the Phase Display submenu. Please see page 54, in the
Reference section of this manual, for details.
