CDMA REPEATER
9. System Set Up and Inspection
9.1 Items to be checked for Opening
A. Confirm AC 108 ~ 127 VAC common use power and power cable.
B. Check if Donor RF input signal from exterior is at normal level.
Caution※
When system operates without input signal confirmed, over-input may cause serious
damage on amplifying degauss because of saturation of output. Therefore, after
checking input signal level by equipment and ALC ON state(on shipment ALC ON)
operate equipment.
C. Put 108 ~ 127 VAC into power connector of equipment to switch ON.
D. Check Alarm LED blinking state of GUI or Repeater’s front board through laptop.
E. When it is judged that Down Link RF input signal from exterior is normal, switch
OFF the Repeater to connect ANT feed and Service ANT to Input/Output Port of
Repeater and switch ON again.
Caution ※
Conclude carefully lest Down Link and Up Link Port be reversed.
9.2 Items to be check after opening
A. Confirm existence of abnormality by checking the alarm LED lighting status of
repeaters.
B. Confirm whether the RF input/output values are normal or not by using GUI.
C. Confirm the normal operation status of repeaters by measuring the characteristics,
etc. of spurious waves of the repeater’s down link and up link output using a
spectrum waveform analyzer by using a coupling terminal beside each input/output
port of the repeater after about 10 or more minutes passes after turning on the
power of repeaters.
D. Optimize the electric wave environments while comparing with the status before
opening about whether there is no electric wave shade region or non-
communicable region by measuring the communication quality in the service region
using a terminal or gauge after normal operation of the repeater.
