R&S TV GENERATOR PAL SGPF电视视频信号发生器

SGPF digitally generates a PAL composite colour video signal (CCVS) coded over the eight-field sequence with a resolution of 12 bits. Two LSI gate arrays convert the Y, CB and CR components into the digital CCVS which features an accurately defined colour-subcarrier/sync-pulse (SC/H) phase. For identification of the beginning of the eight-field sequence, the PAL identification pulse can be inserted into line 7 of the first field.
With the genlock option fitted, SGPF offers the possibility of inserting test signals into a program signal. If no program signal is available, the selected video test pattern is through-connected to the program output.
The test signals numbering more than 30 comprise the following groups:
Test pattern to German FuBK standard or general-purpose test pattern with optional source identification, crosshatch pattern and VTR signal
CCIR insertion test signals
Squarewave signals (50 Hz, 15 kHz, 250 kHz)
Sawtooth signals
Multipulse, H sweep, sin x/x and coring signals
Black burst, vertical staircase, white field and bounce signals
