8.2.3 Test set-up
Television receivers and video tape equipment with built-in television broadcast receiving
facility in the RF recording mode shall be tested at a tuned television channel N and subjected to an
unwanted signal in channel M, level nf, and of the following types:
Unwanted
unwanted signal in channel M, level nf, and of the following types:
Unwanted
signal
types:
A: an unwanted signal at the picture carrier frequency of the relevant channel M
B: two unmodulated signals each at the level as given in the table, one at the relevant picture
carrier frequency +0.5MHz and the other at the picture carrier frequency –0.5MHz.
carrier frequency +0.5MHz and the other at the picture carrier frequency –0.5MHz.
C: a modulated signal at the relevant sound carrier frequency, 1kHz FM at 30kHz deviation
C shall be applied to receivers for countries in which moni-sound television signals of the
systems B and G can be received.
systems B and G can be received.
For television receivers for countries in which also two-sound-channel-television-signals of
the systems B and G with two frequency modulated sound with two frequency modulated
sound carriers can be received.
the systems B and G with two frequency modulated sound with two frequency modulated
sound carriers can be received.
C1: a modulated signal at the relevant frequency of the first sound carrier, 1kHz FM
at 30 kHz deviation, and
C2: a modulated signal at the relevant frequency of the second sound carrier, 1kHz
FM at 30kHz deviation.
C1 and C2 are applied simultaneously.
D: a modulated signal at the relevant picture carrier frequency, 1kHz AM at 80% depth;
E: a modulated signal 1kHz AM at 80% depth.
