Usage Notes
WFM8200 and WFM8300 Waveform Monitors
Set the thresholds for gamut. (See page 119, To Set Up Gamut Checks.) After
selecting the Diamond display, compare the signal to the display to determine
out-of-gamut components. Note the following:
The intensity of a vector indicates its duration.
A momentary out-of-gamut condition appears as a faint trace. Long duration
violations show as a bright trace.
When evaluating out-of-gamut components, consider the following examples.
(See Figure 60.)
Example A:
R - Ok
G > 700 mV
B - Ok
Example B:
R - Ok
G - Ok
B > 700 mV
Example C:
R - Ok
G - Ok, 350 mV
B < 0 mV

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.
