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.
2.4 Operation in a 19" Rack
The R&S ZNB/ZNBT can be mounted in 19" racks using the adapter R&S ZZA-KN5
(order number 1175.3040.00). Proceed according to the mounting instructions supplied
with the rack adapter.
Risk of instrument damage due to insufficient airflow in a rack
If the instrument is run with insufficient airflow for a longer period, the instrument over-
heats, which can disturb the operation and even cause damage.
Make sure that all fan openings are unobstructed, that the airflow perforations are
unimpeded, and that the minimum distance from the wall is 10 cm.
2.5 EMI Suppression
Electromagnetic Interference (EMI) can affect the measurement results.
To suppress generated Electromagnetic Interference:
●
Use suitable shielded cables of high quality (see table below)
●
Always terminate open cable ends
●
Note the EMC classification in the data sheet
Regarding length and quality, the following requirements have to be met for cable that
are directly connected to the R&S ZNB/ZNBT:
