Typical PRE-AMP gain is between 28.5 and 31.5 dBm.
(20) Add highest and lowest PRE-AMP gain recorded in table 3 and then divide sum
by two. Highest and lowest PRE-AMP gain values will be within 1.5 dBm of
calculated average.
(21) Disconnect TI from equipment setup.
(22) Transcribe reference column values recorded in table 3 to reference column in
(23) Connect equipment as shown in figure 1.
