Rackmounting
The R&S
ESW can be installed in a rack using a rack adapter kit (order no. see data
sheet). The installation instructions are part of the adapter kit.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation concept to
ensure that the instruments do not overheat. Insufficient airflow for a longer period can
disturb the operation and even cause damage.
