PRELIMINARY

1X SCt4812ET Lite BTS Optimization/ATP

08/01/2001

4-2

Prerequisites

Before attempting to run any ATP tests, all applicable procedures

outlined in Chapter 3, Optimization/Calibration, must have been

completed successfully (i.e., code load and BLO calibration).

You cannot substitute test equipment with other models not

supported by the CDMA LMF.

NOTE

Before attempting to run any ATP tests, ensure the following:

S BTS has been optimized and calibrated (see Chapter 3).

S LMF is logged into the BTS

S CSMs, GLI2s, BBX2s, MCCs and TSU (if the RFDS is installed)

have correct code load and data load

S Primary CSM and GLI2 are INS_ACT

S MCCs are INS_ACT

S BBX2s are OOS-RAM

S BBX2s are calibrated and BLOs are downloaded

S Test cables are calibrated

S Test equipment is selected

S Test equipment is connected for ATP tests

S Test equipment has been warmed up 60 minutes and calibrated

S GPIB is on

Before the FER is run, be sure that all LPAs are turned

OFF (circuit breakers pulled) or that all transmitter

connectors are properly terminated.

All transmit connectors must be properly terminated for all

ATP tests.

Failure to observe these warnings may result in bodily

injury or equipment damage.

WARNING

TX/RX Antenna Connections

Refer to Figure 1-6 or Figure 1-7 for identification of the transmit and

receive antenna connections where measurement are to be taken.

Directional couplers for signal sampling by the RFDS, if installed, are

integral to the SC4812ET Lite transmit and receive paths in the DRDCs

and TRDCs. As a result, all ATP measurement connections are made at

the antenna connectors on the RF interface panel.
