Test Condition:
At the range of 750MHz (112.25~743.25MHz ) when testing the C/CTB and C/CSO, set 79 PAL-D imitate TV channels signal; set 93PAL-D imitate TV channels signal at the range of 862MHz (112.25~855.25MHz).Choose F1=65MHz, F2=63MHz and F3=57MHz to test when measuring index of max output level in up go transmission. The index of “Carrier to Second Order Inter-modulation Ratio” is tested under the condition of 110dBuV output level, and choose F1=10MHz, F2=60MHz and F3=50MHz three point to test.
