4. The reading on the power reading should be approximately 0dbm. (note: in some
circumstances the net entry may remain active if this is the case the power reading will
be the same as the output for a single user)
5. Set the RW1 to OOS160k. The output rises to the output power for 1 user (21 dBm
for 2.0-2.3GHz , 2.3-2.5GHz , and 1.8-1.9GHz Band and 18dbm for 3.4-3.6GHz
Band).
6. Set RW2 to OOS160k and the power output should rise by 3dB.
7. Set RW3 to OOS160k and the power output should rise by another 4.8dB.
8. Adjust TX Gain for the band of the system under test following the appropriate step
below: 2.0-2.3GHz , 2.3-2.5GHz , and 1.8-1.9GHz Band step 5: 3.4-3.6GHz step 6
9. 2.0-2.3GHz Band, 2.3-2.5GHz Band and 1.8-1.9GHz Band. Adjust the output
power to +25.77dBm. This is equivalent to three downlinks, each with a power of
+21dBm:
a) Using Sitespan highlight the shelf, and edit ‘parent properties’
b) Select ‘Airspan DA CT modem shelf’
c) Adjust the ‘Tx Gain’ and select ‘OK’
Note: To start with, set the TX gain to around 3300.
Check the output power, and repeat step 5c until the output power reaches +25.77dBm
10. 3.4-3.6GHz Band Adjust the output power to +22.77dBm. This is equivalent to three
downlinks, each with a power of +18dBm:
a) Using Sitespan highlight the shelf, and edit ‘shelf properties’
b) Select ‘Airspan DA CT modem shelf’
c) Adjust the ‘Tx Gain’ and select ‘OK’
Note: To start with, set the TX gain to around 3300.
Check the output power, and repeat step 6c until the output power reaches +22.77dBm
11. Record the result (see DLP-013)
12. Re-insert all of the modem cards back into the shelf.
13. Repeat for all other modem shelves
14. Reboot rack by switching rack off at the breakers on the combiner shelf Both breakers
need to be switched. Then restore power to the Rack by switching rack on at the
breakers on the combiner shelf.
