11-32 DRU tests
411-2051-500 Draft 00.01 November 1999
Step Action Observation
18 Use the O command to enter the value of dB4 =
(input level - measured RSSI reading - RF cable
loss value) as the RSSI offset for path B, antenna
4.
>O
<return>
>B dB4 0 0
Antenna Port 1 2 3 4 5 6
RSSI offset dB1 0 0 dB4 0 0
19 For sectored sites only, perform the remaining
portion of this procedure. OMNI cells will only
have two antennas and need not perform the
following steps in this procedure.
20 Change the Antenna path with the N command
to path ‘A’ from the Debug terminal.
>N
<return>
The DRU will request an antenna path
choice. Enter path (A,B, or DIV).
21 Enter the antenna path.
>A
<return>
Current Receiver path:
A
22 Change the antenna ports to 2 and 5 with the M
command from the Debug terminal.
>M
<return>
The DRU will request the port numbers.
Enter a path A port number (1|2|3) and
a path B port number (4|5|6).
23 Enter the antenna ports as two numbers
separated by a space
>2 5
<return>
24 Repeat step 9 to step 18 for all radios being
tested.
Change the connection to the RMC input port
accordingly.
When using the O command to enter
the RSSI offset for path A, antenna port
2 and path B, antenna port 5, make sure
to re-enter the RSSI offset for path A,
antenna port 1 (dB1) and for path B,
antenna port 4 (dB4). For example:
>O
>A DB1 DB2 0
where DB2 = RSSI offset for port 2 and
DB1 = previous value set for port 1.
>O
>B DB4 DB5 0
where DB5 = RSSI offset for port 5 and
DB4 = previous value set for port 4.
