4.4.3.2 High Band Sub-system
Once
the HBE is powered up and all alarms have cleared, the operator can place the HB
repeater in broadcast mode as follows:
1. Configure “SysExciterPwrSetp” so that the HPA input power level is -5.0 dBm, +
0.5
dB – see Figure 4-3
.
o Navigate to the “HPA Overview” page to verify the “HpaInputPower” level – see
Figure 4-4
.
2. Set “SysPowerSetp” to the site specific power level (max. 62.4 dBm) – see Figure 4-3
.
3. Set “SysOfnLoss” to 1.3 dB – see Figure 4-3
.
4. Set “SysOperatingMode” to broadcast – see Figure 4-3
.
o Ensure that the LNA LED is illuminated green.
o The LED’s on the HB HPA’s will flash green and blue alternately as the HPA’s ramp
up to the “SysPowerSetp” target.
o Once the “SysPowerSetp” target is reached, the HPA LED’s will be illuminated
green. It should take approximately 10 minutes for the HB sub-system to ramp up
to full power.
5. Ensure that the “SysPowerSetp” target is reached by viewing “Cpl1ForwardPwr” – see
Figure 4-1
, status window line 11.
o Note: The HBE GUI does not provide any coupler measurements. The coupler
measurements are provided by the LBE GUI.
o The “Cpl1ForwardPwr” value should be 3 dB higher than the “SysPowerSetp” value
as the LB and HB signals are combined on DRU transmit output coupler 1.
6. Ensure that the TRMS HB Status LED is illuminated green.
o The TRMS should scan through the channels at a fast rate of approximately 2
seconds per channel.
