Make a record of the power level from the spectrum analyzer.
Subtract the power level received at the spectrum analyzer from the
power level of the signal generator to obtain the isolation value..
Figure 7
A relatively strong transmitting power from the signal generator is
recommended (excess of 25dBm) for easy recognition and detection by the
spectrum analyzer.
For example, signal generator sends out a signal 1795MHz with 25dBm power
level.
The signal scanned by the spectrum analyzer =
–70dBm.
So, Isolation = 25dBm - (-70dBm) = 95dB
In this condition, to avoid self-oscillation, the gain of booster must be set to be
no more than 80dB, which is 15dB lower than the isolation value.

3.3.1.1 Wall Mount Installation
There are 2 steps of installing the booster. Mounting the bracket on the booster with screws:
See the below in figure 8.
