TVOUT output attenuation
Measured picture carrier in dBuV with the HP8596E Spectrum
Analyzer using a 75 to 50 ohm transformation, all cables losses and
transformation pads having been calibrated.
Measurement used as a reference for other tests: TVout_Ref
Measure in dBc picture carrier at ATT=1 with reference to picture
carrier at ATT=0
Measure in dBc second and third sound harmonics levels in reference
to picture carrier (TVout_Ref).
Measure in dBc, in reference to picture carrier (TVout_Ref), second
harmonic of chroma at channel frequency plus 2 times chroma
frequency, resulting in the following spectrum.
