Phase Format
The PHASE, softkey displays a Cartesian format of the phase portion of the data, measured in degrees.
This format displays the phase shift versus frequency. The phase response of the same filter in a phase-only
format is illustrated in Figure 5-6 on page 5-14.

Group Delay Format
The DELAY, softkey selects the group delay format, with marker values given in seconds. The bandpass
filter response formatted as group delay is shown in Figure 5-7. Group delay principles are described in the
next few pages.
