Noise generator
The satellite band
- Check that the powering measurement in the
fi eld meter in all reference frequencies matches
the theoretical frequencies depending on the
length of the cable and the attenuation factors
of the corresponding frequency, in other words,
that for each powering measurement frequency
should be:
POWERING = POWERING - ATTENUATION
output input
In the example the powering measurements
of the signal at the cable output should be
approximately as follows:
Frequency (MHz)
200
500
800
1000
1750
2150
TOT
2 .- Assessment of the losses in the installation
Powering (dBμV)
of any frequency between 15 and 2150 MHz

It is very useful to see that the distribution network

reaches all the installation sockets without any

losses.

We will take a simple installation in a house as an
