3.7.3 Using a LAN connection
Requires a power sensor with networking capabilities, a LAN power sensor.
3.7.3.1 Connecting a LAN power sensor to the LAN
Depending on the available equipment, you can choose from different ways to connect
a LAN power sensor to a controlling host.
The Ethernet interface of a LAN power sensor requires PoE (power over Ethernet).
See
Chapter 4.5, "LAN PoE interface" , on page 28.
Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, use category 5 cables or better.

1. NOTICE! Incorrectly connecting or disconnecting the power sensor can damage
the power sensor or lead to erroneous results. Ensure that you connect or discon-
nect the power sensor as described in
Chapter 3.4, "Connecting to a DUT" ,
on page 14.
Connect the power sensor to the signal source.
2.
NOTICE! Risk of sensor damage. Only use PoE power sourcing equipment (PSE)
as described in "Choose the PoE power sourcing equipment (PSE) with care"
on page 15.
