4-19 Co-Channel PAL Interference Ratio. ( Co-channel filter ON)
: +1dB typ. +4dB min. NOTE1.
※ NOTE1 :
Desire input signal condition :
a: Modulation : 64QAM b: Guard Interval : 1/32
c: Puncture Rate : 2/3
Undesired(analog) input signal condition :
PAL : Video 75% color bars FM sound : 1kHz tone(P/S : 13dB)
(± 50kHz deviation, freq. P/S : 6.0MHz)
※ Adjacent channel PAL interference test procedure
a: Use changeover switch to select power meter
b: Turn DVB-T source off ; adjust PAL PSP level to -25dBm
c: Turn PAL off ; turn DVB-T on
d: Adjust DVB-T to -25dBm
e: Turn PAL on and increase step attenuator in DVB-T channel until Q.E.F.
※ Adjacent channel DVB-T interference test procedure
a: Use changeover switch to select power meter
b: Turn desired DVB-T source off ; adjust undesired DVB-T level to -35dBm
c: Turn undesired DVB-T sorce off ; turn desired DVB-T on.
d: Adjust desired DVB-T to -35dBm
e: Turn undesired DVB-T on and increase step attenuator in desired DVB-T channel
until Q.E.F.
※ Co-Channel PAL interference test procedure
a: Use changeover switch to select power meter
b: Turn PAL source off ; adjust DVB-T level to -50dBm
c: Turn DVB-T off ; turn PAL on
d: Adjust PAL to -50dBm
e: Turn DVB-T on and increase step attenuator in PAL channel until Q.E.F.
