Chroma/Sound intermodulation
Sound Subcarrier Harmonics
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 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.
Measure in dBc, in reference to picture carrier (TVout_Ref),
intermodulation product at channel frequency plus the sound carrier
frequency (+5,5Mhz) minus the chroma frequency (-4,43Mhz), resulting
in the following spectrum.
Intermodulation product is at the channel frequency +1,07Mhz.
