Measurement Set-up
TVOUT Output Level
Video: 10 steps grey scale
No audio
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
Sound Subcarrier Harmonics
Video: 10 steps grey scale
No Audio signal
Measure in dBc second and third sound harmonics levels in reference to
picture carrier (TVout_Ref).
Picture carrier
Second Harmonics of Chroma subcarrier
No audio
Video: a 700mVpk-pk 100Khz sinusoidal
signal is inserted on the black level of
active video area.
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.
Chroma/Sound intermodulation
No audio signal
Video: 700mVpk-pk 100Khz sinusoidal
signal inserted on the black level of
active video area.This is generated using
a Rohde & Schwarz Video Generator
SAF and inserting the required frequency
from a RF Signal generator.
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.
