4.3 Important Aspects for Test Setup
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT
or test fixture to the instrument's test ports.
►NOTICE! Risk of electrostatic discharge (ESD). Electrostatic discharge (ESD) can
damage the electronic components of the R&S NRX and the device under test
(DUT).
Ground yourself to avoid electrostatic discharge (ESD) damage:
● Use a wrist strap and cord to connect yourself to the ground.
● Use a conductive floor mat and heel strap combination.
EMI impact on measurement results
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated electromagnetic interference (EMI):
●Use suitable shielded cables of high quality. For example, use double-shielded RF
and LAN cables.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet.
●Do not use USB connecting cables exceeding 5 m.
4.4 Placing on a Bench Top
Place the R&S NRX on a stable and level surface. The R&S NRX can be used in hori-
zontal position, standing on its feet, or with the support feet on the bottom extended.

Risk of injury if feet are folded out
The feet can fold in if they are not folded out completely or if the instrument is shifted.
Collapsing feet can cause injury or damage the instrument.
●Fold the feet completely in or out to ensure stability of the instrument. Never shift
the instrument when the feet are folded out.
●When the feet are folded out, do not work under the instrument or place anything
underneath.
●The feet can break if they are overloaded. The overall load on the folded-out feet
must not exceed 500 N.
Risk of injury when stacking instruments
A stack of instruments can tilt over and cause injury if not stacked correctly. Further-
more, the instruments at the bottom of the stack can be damaged due to the load
imposed by the instruments on top.
Observe the following instructions when stacking instruments:
●Never stack more than three instruments. If you need to stack more than three
instruments, install them in a rack.
●The overall load imposed on the lowest instrument must not exceed 500 N.
●It is best if all instruments have the same dimensions (width and length).
If you need to stack smaller instruments on the top, the overall load imposed on the
lowest instrument must not exceed 250 N.
●If the instruments have foldable feet, fold them in completely.
