Test Equipment Set-up
Purpose
This section covers other test equipment and peripherals not covered in
Chapter 3. Procedures for the manual testing are covered here, along
with procedures to calibrate the TX and RX cables using the signal
generator and spectrum analyzer.
Equipment Warm up
NOTE
Warm-up BTS equipment for a minimum of 60 minutes prior to
performing the BTS optimization procedure. This assures BTS
site stability and contributes to optimization accuracy. (Time
spent running initial power-up, hardware/
firmware audit, and BTS download counts as warm-up time.)
CAUTION
If any piece of test equipment (i.e., test cable, RF adapter) has
been replaced, re-calibration must be performed. Failure to do so
could introduce measurement errors, resulting in incorrect
measurements and degradation to system performance.
NOTE
Calibration of the communications test set (or equivalent test
equipment) must be performed at the site before calibrating the
overall test set. Calibrate the test equipment after it has been
allowed to warm-up and stabilize for a minimum of 60 minutes.
Prerequisites
Prior to performing any of these procedures, all preparations for
preparing the LMF, updating LMF files, and any other pre-calibration
procedures, as stated in Chapter 3, must have been completed.
