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 1.0 GHz
Measure in dBc, in reference to picture carrier (RFout_Ref), spurious levels
falling into video bandwidth Fo+/-5.0 MHz (15.125 KHz & 31.25 KHz from
reference dividers and 4 MHz from crystal).
The Video signal is demodulated on the spectrum analyzer, and the peak level
of the 100 KHz signal is measured as a reference. The frequency is then swept
from 100 KHz to 5.0 MHz, and then the difference in dBc from the 100 KHz
reference level is measured.
