NOTE: For informaon about the actual amount of signal loss caused by equipment and other
factors, see your vendor documentaon for that equipment.
2. Calculate the (
P
M
) by subtracng (
LL
) from (
P
B
):
P
B
– LL = P
M
(13 dBm) – (0.5 dBm [HOL]) – ((5) * (0.5 dBm)) – ((2) * (0.5 dBm)) – ((2 km) * (1.0 dBm/km)) – (1 dB
[CRM]) = P
M
13 dBm – 0.5 dBm – 2.5 dBm – 1 dBm – 2 dBm – 1 dBm = P
M
P
M
= 6 dBm
The calculated power margin is greater than zero, indicang that the link has sucient power for
transmission. Also, the power margin value does not exceed the maximum receiver input power.
Refer to the specicaon for your receiver to nd the maximum receiver input power.
