Measurement Set-Up
RFOUT Output Level
Measured picture carrier in dB μ V with the HP8596E Spectrum Analyzer using a
75 to 50 ? transformation, all cables losses and transformation pads having been
calibrated.
Measurement is used as a reference for other tests: RFOUT
Sound Subcarrier Harmonics
Measure in dBc second and third sound harmonics levels in reference to picture
carrier (RFOUT).

Video: a 700 mV (pp) 100 kHz sinusoidal
signal is inserted on the black level of active
video area.
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.

Video: 700 mV (pp) 100 kHz sinusoidal signal
inserted on the black level of active video
area.This is generated using a Video
Generator and inserting the required
frequency from a RF Signal generator.
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.
