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
Cong
uration menu)
