Philips PM5508 Pattern Pictures
I am not sure what the "DELAY", "PHASE" and "MATRIX" patterns look like on a Philips PM5508 TV pattern generator.
However, the service manual specifies them as:
"DELAY"
4 vertical bars:
146º (G-Y) = 0
180º (R-Y) = 0
90º (B-Y) = 0
Grey 40%
NTSC encoded, however with PAL A-B burst.
"PHASE"
Same bars as "DELAY" with PAL A-B burst.
However, upper half: PAL encoded with half the saturation and lower half: only chroma during the "positive" PAL lines where burst phase = 135º
"MATRIX"
Same as "DELAY" with PAL A-B burst, however, completely PAL encoded.
Where can I find pictures of those patterns?
