Note1 :
Desire input signal condition
a : Modulation - 64QAM
b : Guard Interval - 1/32
c : Puncture Rate - 2/3
Undesired input signal condition :
PAL : Video 75% color bars
FM sound : 1kHz tone (P/S : 13dB,
50kHz deviation, freq. P/S : 6.0MHz)
Adjacent & Image channel PAL interference test procedure
a. Turn DVB-T source off ; adjust PAL PSP level to -25dBm
b. Turn PAL off ; turn DVB-T on
c. Adjust DVB-T to -25dBm
d. Turn PAL on and increase step PAL level to see the pixelation on the screen
e. Note protection ratio as the difference value between DVB-Tand PAL's level
Co-Channel PAL interference test procedure
a. Turn PAL source off ; adjust DVB-T level to -50dBm
b. Turn DVB-T off ; turn PAL on
c. Adjust PAL to -50dBm
d. Turn DVB-T on and increase step attenuator in PAL channel until QEF.
