Example:
Expected output level at top of stack = 14 dBm.
Label on diplexer filter/XMT filter shows insertion loss is 2dB.
Nominal high power out of XMTR = 16 dBm
(14 dBm + 2 dBm = 16 dBm).
Set nominal low power level for 6 dBm
(10 dB down from 16 dBm).
Determine XMTR nominal
high and low output level:
c
XMTR nominal high output level
= level at top of stack + insertion
loss of diplexer filter/XMT filter
(marked on label on filter.
XMTR nominal low output level
= XMTR nominal high output
level – 10 dB.
