Are you familiar with NPO and the RMS indicators ?
If yes, then check (before and after ANY installation):
path balance of TRX –> to check if your ANY is functionning properly.
average rxlev per trx, in DL and in UL
average timing advance per trx
and more interestingly
vector “rxlev per TA and per sample”.
with these indicators, you’ll have a very clear picture of what is happening on the radio.
