7.6.6 Defining D elay
This section describes how to define RX and TX feeder delay.
The delay parameter specifies the RF signal delay in the feeder. If the total
feeder delay value, measured and calculated in chapter Antenna System
Test, differs from the default delay (configuration dependent) then the delay
parameter must be updated to the total feeder delay value ( 0-10,000 ns). See
test record from Antenna System Test.
1. On the Configuration menu, click Define and Delay to open the Define
Delay window.
2. Select the cable for w hich delay is to be defined, and click Run.
3. Enter the delay value (in ns) from the Test Record for Antenna System
Testsand click OK.
4. Repeat steps 2 and 3 for the remaining cables.
5. Click Close when finished.
7.6.7 Defining GPS Pa
rameters
This section de
scribes how to set the GPS parameters, if applicable.
Note: These parameters do not apply to BSS R9 software.
To be able to use GPS as a synchronization source, the RBS must be equipped
with a GPS receiver.
A GPS receiver is used to achieve a synchronized radio network and works as
reference for RF frequency generation and GSM time-based counters.
Parameters for the GPS are set according to the table below.
