(Note1) Y/C Crosstalk: Reference Measurement: Results: 1.7dB (p-p)
Composite signalÆENCV, no inputÆENCRC, TVRC is terminated by 75Ohm.
Y/C Crosstalk: Measurement: Results: -43.3dB (p-p)
YÆENCV, CÆENCRC, TVRC is terminated by 75Ohm.
Y/C Crosstalk calculation: -43.3dB (p-p) - 1.7dB (p-p) = -45.0dB (p-p)
