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 15.
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 17.
Connect the RJ-45 Ethernet connector of the sensor to the output of the PoE injec-
tor.
3. Connect the PoE injector to a power supply.
4. Connect the controlling host to the input of the PoE injector.
5. Establish a network connection between the power sensor and the controlling host.
3.7.3.2 Establishing a connection to the network
There are two methods to establish a network connection:
●
Power sensor and controlling host are connected to a common network
(infrastructure network).
