RF Path Audit

PRELIMINARY

SCt300 BTS Hardware Installation, ATP and FRU Procedures

7-44

Test Equipment Setup

The BTS RF path is calibrated in the factory. There is no need to

calibrate during installation.

All tests are measured with respect to the Antenna output

connector. Additional losses must be compensated for. RF

calibration does not take the following into consideration:

– Antenna feedline losses.

– Antenna gain.

IMPORTANT

Transmit (TX) Audit

Prerequisites

The following steps must be completed before you do the TX RF path

audit.

1. MAWI has correct code load and data load.

2. MAWI is INS.

3. Test equipment and test cables are calibrated and connected to the

TX antenna outputs.

4. LMF is logged into the BTS.

Procedure

Follow the steps in Table 7-26 to audit the calibration.

To prevent damage to the test equipment all transmit (TX)

test connections must be via the 30 dB in-line attenuator

for the MicroCell BTS.

CAUTION

The TX audit actions can be performed separately by using

the applicable Device menu selections.
