1X UBS Macro B T S Optimization/A TP FRU Optimization/A TP T est Matrix
Not every procedure required to bring the site back on line is indicated in T able B -2 .
It is meant to be used as a guideline ONL Y . The table assumes that the user is
familiar enough with the UBS Optimization/A TP procedure to understand which test
equipment set ups, test set calibrations, and UBS site preparation will be required
before performing the T able # procedures referenced.
V arious passive UBS components (such as the TX and RX directional couplers, etc.) only call for
a TX or RX calibration audit to be performed in lieu of a full path calibration. If the RX or TX
path calibration audit fails, the entire RF path calibration will need to be repeated. If the RF
path calibration fails, further troubleshooting is warranted.
Whenever any unit is replaced, it is assumed that only power to the unit being replaced is
turned off via the breaker supplying that unit.
