SCt300 BTS Hardware Installation, ATP and FRU Procedures

PRELIMINARY

Purpose

The following test equipment setup applies to the BTS Acceptance Test

Procedure (ATP).

Required Test Equipment

The following pieces of test equipment will be required to perform these

ATP tests:

S LMF

S Power Meter

S Communications Test Set

To prevent damage to the test equipment, all Microcell

transmit (TX) tests must be made using the 30 dB

attenuator.

CAUTION

Test Set Calibration

Background

Proper test equipment calibration ensures that the test equipment and

associated test cables do not introduce measurement errors, and that

measurements are correct.

If the test set being used to interface with the BTS has been

calibrated and maintained as a set, this procedure does not

need to be performed. (Test Set includes LMF terminal,

communications test set, additional test equipment,

associated test cables, and adapters.)

NOTE

This procedure must be performed prior to beginning the optimization.

Verify all test equipment (including all associated test cables and

adapters actually used to interface all test equipment and the BTS) has

been calibrated and maintained as a set.

If any piece of test equipment, test cable, or RF adapter,

that makes up the calibrated test equipment set, has been

replaced, re-calibration must be performed. Failure to do so

can introduce measurement errors, resulting in incorrect

measurements and degradation to system performance.
