The bottom of back side for this terminal is consists of Input Power, connector of SRG-
1150DN/SRG-1250DN, W/K Whip antenna for receiving, coaxial connector, EARTH socket,
Keyboard connector and EMC LIGHT connector.
3-2 CONNECTION BOARD T-020 (OLD) / G-1151 (NEW)
T-020 / G-1151 is the PCB which is connecting CPU BOARD and other PCBs when receiving
signal by NBDP.
When receiving signal are generated through receiving unit (T-022 / T-132) and then it deliver to
SRG-1150DN / SRG-1250DN.
3-3 NBDP Receiving Unit T-022(OLD) / T-132(NEW)
As main receiving unit of NBDP, it consists of frequency filter and amplifier, MIXER, ATT,
AGC, B.K control unit.
After the signals received through MF/HF Antenna amplify with wide amplifier, it is divided into
two parts through SPLITTER (SP1).
