Second Harmonics of Chroma Subcarrier
Chroma/Sound Intermodulation
Measured picture carrier in dBµV with the HP8596E Spectrum Analyzer using a
75 to 50 Ω transformation, all cables losses and transformation pads having been
calibrated.
Measurement is used as a reference for other tests: RFOUT
Measure in dBc second and third sound harmonics levels in reference to picture
carrier (RFOUT).
Measure in dBc, in reference to picture carrier (RFOUT), 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 (RFOUT), intermodulation product
at channel frequency plus the sound carrier frequency (+5.5 MHz) minus the
chroma frequency (-4.43 MHz), resulting in the following spectrum.
Intermodulation product is at the channel frequency +1.07 MHz.
