Checking Gamut
1. Perform the Setup for Gamut Checks
procedure. Select Diamond in step 5.
(See page 46.)
2. Compare the sig
nal to the display to
determine out of gamut components,
noting the following:
The intensity of a vector indicates its
duration.
A momentary ou
t-of-gamut condition
appears as a faint trace. Long
duration violations show as a bright
trace.

out-of-gamut signals.
3. Consider the following examples when
evaluating for out of gamut components:
A. Example A:
R-Ok
G > 700 mV
B-Ok
B. Example B:
R-Ok
G-Ok
B > 700 mV
C. Example C:
R-Ok
G - Ok, 350 mV
B<0mV
Usage Notes
As wit
h the lightning display, bending of the transitions indicates timing delays. When a color bar signal is applied, the
vertical axis becomes an indicator of delay errors.
On the Diamond display, monochrome signals appear as vertical lines. Nonlinear component processing, such as from a
gamma corrector that alters white balance, can cause deviations along the vertical axis.
To isolate gamut bright-ups, try the following:
Use the LINE SEL button to select individual lines
Use the PICT display to examine the signal (turn on gamut bright-ups in the Display Settings submenu of the
Config
uration menu)
