FER Acceptance Test
Follow the steps in Table 4-12 to verify the FER on RX antenna paths
using selected MCCs and BBXs.
Table 4-12: Test FER
Step Action
1 Set up the test equipment for RX acceptance tests per Table 4-3.
2
If a companion frame is being tested and either BOTH or DIV is to be selected in step NO TAG,
perform the additional test equipment set–up in Table 4-4 for the diversity RX portion of the ATP.
NOTE
If the LMF has been logged into the BTS with a different Multi–Channel Preselector setting than the
one to be used for this test, the LMF must be logged out of the BTS and logged in again with the new
Multi–Channel Preselector setting. Using the wrong MPC setting can cause a false test failure.
3 Select the BBXs and MCCs to be tested.
4 Click on Tests in the BTS menu bar, and select RX > FER... from the pull–down menu.
5
Select the appropriate carrier(s) and sector(s) (carrier-bts#-sector#-carrier#) from those displayed in the
Channels/Carrier pick list.
NOTE
To select multiple items, hold down the Shift or Ctrl key while clicking on pick list items to select
multiple carrier(s)–sector(s).
6
Verify that the correct channel number for the selected carrier is shown in the Carrier # Channels
box. If it is not, obtain the latest bts–#.cdf (or bts–#.necf) and cbsc–#.cdf files from the CBSC.
NOTE
If necessary, the correct channel number may be manually entered into the Carrier # Channels box.
7 Select the appropriate RX branch (Both, Main, or Diversity) in the drop–down list.
NOTE
If a companion frame with the inter–frame diversity RX cabling disconnected is being tested do not
select BOTH in this step. The RX main and diversity paths must be tested separately for this
configuration because each requires a different Multi–Coupler Preselector type to provide the proper
test signal gain.
8
In the Rate Set box, select the appropriate data rate (1=9600, 2=14400, 3=9600 1X) from the
drop–down list.
NOTE
The Rate Set selection of 2 is only available if non–1X cards are selected for the test.
The Rate Set selection of 3 is only available if 1X cards are selected for the test.
9 Click OK to display a status bar followed by a Directions pop-up window.
10
NOTE
When testing diversity RX paths on companion frames, be sure to follow the RX test cable connection
information in Table 4-1 or Table 4-2, as applicable, during this step.
Follow cable connection directions as they are displayed, and click the Continue button to begin
testing. As the ATP process is completed, results will be displayed in the status report window.
11 Click the Save Results or Dismiss button. If Dismiss is used, the test results will not be saved in the
test report file.
