Checking Gamut
Set the thresho
lds for gamut. (See page 119, To Set Up Gamut Checks.) After
selecting the Diamond display, compare the signal to the display to d etermine
out-of-gamut components. Note the following:
The intensity of a vector indicates its duration.
Amomentary
out-of-gamut condition appears as a faint trace. Long duration
violations show as a bright trace.
When evalua
ting out-of-gamut components, consider the following examples.
(See Figure 60.)
Example A:
R-Ok
G>700mV
B-Ok
Example B:
R-Ok
G-Ok
B>700mV
Example C:
R-Ok
G-Ok,
350 mV
B<0mV

Usage Notes
As with 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.
