4.4 Connecting to a DUT
The R&S NRQ6 has fan openings at both sides of the casing, as shown in Fig-
ure 5-1 . When connecting the R&S NRQ6 to a DUT and setting up the measure-
ment assembly, be careful to allow sufficient airflow.
Risk of damage due to insufficient airflow
If the R&S NRQ6 is run with insufficient airflow for a longer period, the
R&S NRQ6 overheats. Overheating can disturb the operation, even cause
damage and lead to wrong measurement results.
Make sure of the following:
●
All fan openings are unobstructed.
●
Airflow perforations are unimpeded.
●
Minimum distance between the fan openings and any object is 10 cm.
To connect to the DUT
For connecting the R&S NRQ6 to a DUT, use the RF connector of the
R&S NRQ6. For details, see Chapter 5.1, "RF Connector" , on page 32.
1. Ensure that the RF connector of your DUT is compatible with the RF connec-
tor of the R&S NRQ6.
2. Insert the RF connector straight into the RF output of your DUT. Take care not
to tilt it.

3. 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.
Tighten the RF connector manually.
4. Tighten the RF connector using a torque wrench with the nominal torque of
1.36 Nm (12'' lbs) to ensure maximum measurement accuracy.
