Chroma/Sound Intermodulation
Measure in dBc, in reference to picture carrier (RFout_Ref), 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.
Measure in dBc, in reference to picture carrier (RFout_Ref), second and third
harmonic of channel frequency, resulting in the following spectrum.
Measure in dBμV spurious levels at 0.25, 0.5, 0.75 and 1.5 times channel
frequency, resulting in the following spectrum
Measure from 40 MHz to 1 GHz (Fo = 460 - 880 MHz)
