2) The signal booster is equipped with a -30 dB
signal sampler port following the final output
amp (part of the Duplexer assembly). This port
is for the connection of test equipment such as
a spectrum analyzer and will allow the observa-
tion of the amplifier output at a considerably
reduced output level. This decoupling figure
needs to be added to a measured signal value
in order to arrive at the actual signal level.
3) With a spectrum analyzer connected to the sig-
nal sampler port (see
Figure 8
), have person-
nel with handheld radios move to several
predetermined points and key their radios.
Record the level of these signals as observed
on the analyzer and also record the location of
the person transmitting. In this way, a map of
the systems performance can be generated.
