Noise generator
The satellite band
- Check that the powering measurement in the
field 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
output
= POWERING
input
- ATTENUATION
TOT
In the example the powering measurements
of the signal at the cable output should be
approximately as follows:
Frequency (MHz) Powering (dBµV)
200 73.2
500 68.3
800 66.15
1000 63.5
1750 59.1
2150 59.55

.- Assessment of the losses in the installation
of any frequency between 15 and 2150 MHz
(see the noise generator specifications):
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
example:
