TX Code Domain Power Noise Floor Acceptance Test – continued
July 1999
4-19
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Prerequisites
Before attempting to run any ATP tests, ensure the following have been
completed:
 CSMs, GLI2s, BBX2s, and MCCs have correct code load and data
load
 Primary CSM, GLI, and MCCs are INS
 BTS has been Optimized/Calibrated
 BBX2s are OOS–RAM
 Test equipment is connected for ATP tests (see Figure 3-16 through
Figure 3-19).
 Test equipment is warmed up 60 minutes and calibrated
 Test cables are calibrated
 GPIB is on
Code Domain Power ATP
Follow the steps outlined in Table 4-8 to verify the Code Domain Power
of each BBX carrier keyed up at a specific frequency.
Table 4-8: Code Domain Power Test
 Step Action
1 Select the BBX2(s) and MCC(s) to be tested.
2 From the Tests menu, select Code Domain Power
3 Select the appropriate carrier(s) displayed in the Channels/Carrier pick list (use the Shift or Ctrl
keyboard key to select multiple items).
4 Type the appropriate channel number in the Carrier n Channels box.
Click OK.
5 Follow the cable connection directions as they are displayed.
6 Click on OK to close the status report window.
NOTE
Verify the active channel code domain power levels, which have been set on ODD numbered
Walsh channels, using the OCNS command. This is done by verifying that Pilot Power (dBm)
minus OCNS Power (dBm) is equal to
10.2 + 2 dB and the noise floor of all inactive “OFF” Walsh
channels measures
< –27 dB (with respect to total CDMA channel power).
