For time scale measurements
use the
analyser 'group delay' mode.

4.1.3 PHASE
Phase presentation:
* [normal]
Phase presented
as an angle between
4-
180°
and
-180°
Angles >
±
180°
are wrapped to obtain
an equivalent
relative angle.
A
plot
of wrapped
phase results relating to
a system
at resonance could
appear thus:

[unwrapped]
Phase
presented as an absolute
angle between
0°
and ± n°. A plot of
unwrapped
phase results from
the
same basic
data as the
normal
plot
above
would appear thus:
