- Check that the powering measurement in the FSM meter in all reference frequencies matches<br />
the theoretical frequencies depending on the length of the cable and the attenuation factors of<br />
the corresponding frequency, in other words, that for each powering measurement frequency<br />
should be:<br />
POWERINGoutput =POWERINGinput - TOTAL ATTENUATION<br />
In the example the powering measurements of the signal at the cable output should be approximately<br />
as follows:<br />
Frequency (MHz) Powering (dBuV)<br />
200 73.2<br />
500 68.3<br />
800 66.15<br />
1000 63.5<br />
1750 59.1<br />
2150 59.55<br />
2.- Assessment of the losses in the installation of any frequency between 15 and 2150 MHz (see the<br />
noise <strong>generator</strong> specifications): It is very useful to see that the distribution network reaches all<br />
the installation sockets without any losses.
