TX Path Audit procedure
After a TX calibration has been performed, or if verification of BLO data
in the CAL file is required, follow the procedure in Table 3-37 to
perform a BTS TX path audit.
Table 3-37: 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 3-33 (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.
8 From the Test Pattern pick list, select a test pattern.
– Selecting Pilot (default) performs tests using a pilot signal only.
– Selecting Standard performs tests using pilot, synch, paging and six traffic channels. This
requires an MCC to be selected.
– Selecting CDFPilot performs tests using the CDF value for pilot gain and IS–97 gain values
for all the other channels included in the Standard pattern setting (paging, synch, and six
traffic). Using this pattern setting requires the selection of both a BBX and at least one MCC.
– Selecting CDF performs tests using pilot, synch, paging and six traffic channels, however, the
gain for the channel elements is specified in the CDF file.
9 Click OK to display the status report window followed by a Directions pop-up window.
10 Follow the cable connection directions as they are displayed. When the calibration process is
completed, results will be displayed in the status report window.
11 Click on the Save Results or Dismiss button, as desired, to close the status report window.
