11 Modulator High-Frequency Characteristics
Each of the characteristics listed in Table 20 is classified as one of the following types:
See Section 14, “Characterization Measurement Conditions,” for each C-type parameter.
Unless otherwise stated, V
grey scale and RF output into 75-Ω load.
TVOUT output level
UHF oscillator frequency
VHF range
TVOUT output attenuation
Sound subcarrier harmonics
(Fp + n × Fs)
Second harmonic of chroma
subcarrier
Chroma/sound intermodulation:
Fp + (Fsnd – Fchr)
Fo (picture carrier) harmonics
Out-of-band (picture carrier)
spurious
In-band spurious (Fo at 5 MHz)
Notes:
1. See Section 14, “Characterization Measurement Conditions.”
2. See Figure 3.
3. Picture carrier harmonics are highly dependent on PCB layout and decoupling capacitors.
