3.6.4 Vertical sensitivity
a) Adjust the TV to a “PP” condition.
b) Apply to the antenna input a 60dBµV signal with 88% AM modulation with
PAL-M color pattern (frequency and channel factory defined), and FM sine
wave 1kHz audio modulation +-25 kHz deviation.
c) Observe the TV screen under test and reduce the output generator level
until maintain the stability of the image in the vertical direction and when
there is the instability of the image in the vertical direction, increase the
output generator level until the stability of the image comes back in the
vertical direction. At this condition the output generator level represents the
vertical sensitivity in dBµV.
Note.: If the TV under test is two or three-system mode, repeat this procedures for
the PAL-N and NTSC-M signal system.
Condition Minimum Nominal Maximum Unit
PAL-M - 20,00 23,00 dBµV
PAL-N - 20,00 23,00 dBµV
NTSC-M - 20,00 23,00 dBµV
3.6.5 Chrome sensibility
a) Adjust the TV to a “PP” condition.
b) Apply to the antenna input a 60dBµV signal with 88% AM modulation with
PAL-M color pattern (f requency and channel factory defined), and FM sine
wave 1kHz audio modulation +-25 kHz deviation.
c) Observe the TV screen under test and reduce the output generator level
until the color pattern be visible. At this condition the output generator level
represents the sensibility of chrome in dBµV.
Note.: If the TV under test is two or three-system mode, repeat this procedures for
the PAL-N and NTSC-M signal system.
Condition Minimum Nominal Maximum Unit
PAL-M - 28,00 30,00 dBµV
PAL-N - 28,00 30,00 dBµV
NTSC-M - 28,00 30,00 dBµV
