4.2.6.3 Repeater Settings Setup
From the Donor-0 Status (Figure 4.7) or the Remote-0 Status (Figure 4.9), click the
“CHG” check box next to the desired control items that you wish to change, then
modify the values and click the “Update” button to allow the changes to take affect.
To set up the system so that the RU RF output of 20 watts is not exceeded, enter a
value of 43dBm into the upper limit. Under certain circumstances where the output
power exceeds this value, the AGC function will provide attenuation so as not to
damage the unit. The lower power limit can be set as 17dBm.
Please note that the power level readings on the LMT versus the actual RF power
can differ by up to 1dB. For this reason the offset feature is included in the LMT.
The initial attenuator settings on the LMT should be as follows:
Donor DL0 and DL1 ATT: 13 dB Donor UL0 and UL1 ATT: 18 dB
