To disconnect from the DUT
1. NOTICE! Risk of damaging the center pin of the RF connector. Only rotate the
hex nut of the RF connector. Never rotate the R&S NRQ6 itself.
Carefully loosen the union nut at the front of the RF connector of the
R&S
NRQ6.
2. Remove the R&S NRQ6.
4.5 Connecting to a Power Supply
The power for the R&S NRQ6 is supplied over the LAN PoE+ interface. See also
Chapter 5.3, "LAN PoE+ Interface" , on page 33.
Risk of R&S NRQ6 damage
Make sure to use only PoE+ power sourcing equipment (PSE) as specified
in the IEEE 802.3at standard. Otherwise, the following consequences can
occur:
●
If too much power is supplied, the R&S NRQ6 can get overheated which
can result in damage.
●
If the supplied power is not sufficient, the R&S NRQ6 does not work
properly or not at all.
To connect to a LAN PoE+ interface
1. Use a suitable cable as described in Chapter 5.3, "LAN PoE+ Interface" ,
on page 33.
2. Connect one end of the cable to the LAN interface of the R&S NRQ6.
3. Connect the other end of the cable to one of the following:
● PoE+ port of a LAN switch:
See Chapter 4.6.1.1, "Setup with a PoE+ Ethernet Switch" , on page 20.
● Output of a PoE+ injector:
See Chapter 4.6.1.2, "Setup with a PoE+ Injector and a Non-PoE+ Ether-
net Switch" , on page 21.
