perform a BTS TX path audit.
Table 6-37: Procedure for BTS TX Path Audit
n Step Action
1 If it has not already been done, configure test equipment for TX path audit by following the procedure
in Table 6-31 (TX audit uses the same configuration as TX calibration).
2 Select the BBX(s) to be audited.
3 If the Test Pattern to be used is Standard, CDFPilot, or CDF, select at least one MCC (refer to
“Test Pattern Drop–down Pick List” under “TX Calibraton and the LMF” in this section).
4 Click Tests in the BTS menu bar, and select TX > TX Audit... from the pull–down menus. A
CDMA Test Parameters window will appear.
5 Select the appropriate carrier(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 If at least one MCC was selected in Step 3, select the appropriate transfer rate (1 = 9600, 3 = 9600
1X) from the drop–down list in the Rate Set box.
NOTE
The rate selection of 3 is only available if 1X cards are selected for the test.
