C.2.2.1The TV receiver is fed by an r.f. TV signal with a level of 65 dB/µV
on 75W and with the following test modulations:
a) Colour Television
Radio frequency signal: a full TV signal with modulated picture
chrominance and sound carrier.
•
The sound modulation factor is 100% at 1000Hz.
•
The picture modulation content is a colour bar test pattern with:
100%
reference white level bar;
0%
reference black level bar; and
75%
Amplitude (reference made to the white level) and;
100%
saturation.
b) Monochrome television
Radio frequency signal: a full TV signal with modulated picture and sound
carrier.
•
Sound modulation: see Item a) above.
•
The picture modulation is a monochrome test pattern with a black
and white level according to Item a) and an average overall picture
content of 50% of the reference white level.
C.2.2.2 The receiver shall be tuned and adjusted according to Clause 37 of
IEC publication 107-1
The white reference level corresponds to 80 cd/m² and the black level to
less than 2 cd/m². The magenta bar corresponds to 30 cd/m².
The volume control is set in such a manner that one-eighth of rated output
power is obtained, measured at the loudspeaker terminals, at a frequency of
