DRAFT
Pilot Time Offset
The Pilot Time Offset is the difference between the CDMA analyzer
measurement interval (based on the BTS system time reference) and the
incoming block of transmitted data from the BTS (Pilot only, Pilot
Gain = 262, PN Offset = 0).
Code Domain Power (Primary & Redundant BBX)
This test verifies the code domain power levels, which have been set for
all ODD numbered Walsh channels, using the OCNS command. This is
done by verifying that the ratio of PILOT divided by OCNS is equal to
10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF”
Walsh channels measures
< –27 dB (with respect to total CDMA channel
power).
Frame Error Rate
The Frame Error Rate (FER) test verifies RX operation of the entire
CDMA Reverse Link using all equipped MCCs assigned to all
respective sectors/antennas. This test verifies the BTS sensitivity on all
traffic channel elements currently configured on all equipped MCCs at
an RF input level of –119 dBm (or –116 dBm if using TMPC).
ATP Test Procedure
Follow the procedure in Table 4-1 to perform any ATP test.
Table 4-1: ATP Test Procedure
n Step Action
1 Be sure that all prerequisites have been met.
2 Select the device(s) to be tested.
IMPORTANT! Only one carrier can be tested at a time. All PAs must be INS during testing.
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 From the Tests menu, select the test you want to run.
4 Select the appropriate carrier (carrier-bts#-sector#-carrier#) displayed in the Channels/Carrier
pick list.
NOTE
To select multiple items, hold down the <Shift> or <Ctrl> key while making the selections.
5 Enter the appropriate channel number in the Carrier n Channels box.
The default channel number displayed is determined by the CdmaChans[n] number in the
cbsc–n.cdf file for the BTS.
6 If applicable, select Verify BLO (default) or Single–sided BLO.
