Rohde and Schwarz SGPF

The Rohde & Schwarz SGPF is a PAL composite color video signal (CCVS) generator that digitally produces test signals coded over an eight-field sequence with 12-bit resolution. It converts Y, CB, and CR components into a precision CCVS output with accurately defined color-subcarrier/sync-pulse (SC/H) phase relationships. The unit employs two LSI gate arrays to ensure signal integrity and supports PAL identification pulse insertion into line 7 of the first field for sequence verification.
