Checking RGB Gamut

Quad Diamond (Requires Option S3D)– Use to show the disparity between
the left and right channels of a 3D signal. (See page 42, Gamut Display.)
Arrowhead – Use to detect composite gamut errors, without employing a
composite encoder.
Spearhead – Use to detect RGB gamut errors.
4. Press the GAMUT button to dismiss the pop-up menu.
5. Press the CONFIG button and select Gamut Thresholds.
6. Set the thresholds as desired.
The Diamond and Spearhead displays effectively show how the R, G, and B
signals relate. The Diamond display is a good tool for detecting gamut errors.
Spearhead requires Option PROD.
To form the Diamond display, the instrument converts the Y, P
recovered from the serial signal to R, G, and B. To predictably display all three
components, they must lie between peak white, 700 mV, and black, 0 V.
