4.3 CDMA Transmitter and Receiver Test --- TX and RX Tester Mode
(a) Setup for CDMA TX/RX measurement
In transmitter measurement, the MT8801C receives the modulated signal
(RF signal) from the DUT to measure modulation accuracy and other con-
ditions.
In the call processing test, the DUT receives the forward signal (RF signal)
from the MT8801C; the MT8801C receives the reverse signal (RF signal)
from the DUT.
