TX Waveform Quality (Rho) Acceptance Test
PRELIMINARY
1X SC480 BTS Hardware Installation, Optimization/ATP, and FRU
MAY 2004
7-14
Background
Overview – This test verifies the transmitted pilot channel element
digital waveform quality of each operator–selected BBX carrier keyed up
at a specific frequency specified in the current CDF. All tests are
performed using the external, calibrated test equipment controlled by the
same command. All measurements are made at the appropriate TX
antenna connector.
Equipment Operation During Testing – Pilot gain will be set to 262
for each antenna, and all TCH elements from the MCCs will be
forward–link disabled. The selected BBXs will be keyed up using both
bbxlvl and BLO to generate a CDMA carrier (with pilot channel
element only, Walsh code 0). RF output power is set at 40 dBm as
measured at the appropriate BTS TX antenna connector.
Test Measurements – The test equipment will measure and return the
pilot channel element digital waveform quality (rho) percentage,
verifying that the result meets the following specification:
Waveform quality (Rho) should be >
0.98.
Waveform Quality (Rho)
Acceptance Test
Follow the steps in Table 7-6 to verify the pilot channel element
waveform quality (rho) on the TX antenna paths for the selected BBXs.
Table 7-6: Test Waveform Quality (Rho)
Step Action
1 Set up the test equipment for TX acceptance tests per Table 7-1.
2 Select the BBXs to be tested.
3 Click on Tests in the BTS menu bar, and select TX > Rho... from the pull–down menus.
4
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).
5
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 and cbsc–#.cdf files from the CBSC.
NOTE
If necessary, the correct channel number may be manually entered into the Carrier # Channels box.
6 Click OK to display a status bar followed by a Directions pop-up window.
7 Follow the 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 a status report window.
