Table 11-3 shows the DRU configuration for RSSI characteristics and Table
11-4 shows the RSSI measurement characteristics.
Step
Action
Observation
25
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 ).
26
Enter the antenna path.
>A
<return>
Current Receiver path:
A
27
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).
28
Enter the antenna ports as two numbers
separated by a space.
>3 6
<return>
29
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
3 and path B, antenna port 6, make sure
to re-enter the RSSI offset for path A,
antenna ports 1, 2 (dB1 and dB2) and
for path B, antenna ports 4, 5 (dB4 and
dB5). For example:
>O
>A DB1 DB2 DB3
where DB3 = RSSI offset for port 3,
DB2 = previous value set for port 2, and
DB1 = previous value set for port 1.
>O
>B DB4 DB5 DB6
where DB6 = RSSI offset for port 6,
DB5 = previous value set for port 5, and
DB4 = previous value set for port 4.
