Choosing the operating site
Specific operating conditions ensure proper operation and avoid damage to the
product and connected devices. For information on environmental conditions
such as ambient temperature and humidity, see the data sheet.
Electromagnetic compatibility classes
The electromagnetic compatibility (EMC) class indicates where you can operate
the product. The EMC class of the product is given in the data sheet under "Gen-
eral data".
●
Class
B equipment is suitable for use in:
– Residential environments
– Environments that are directly connected to a low-voltage supply network
that supplies residential buildings
●
Class
A equipment is intended for use in industrial environments. It can cause
radio disturbances in residential environments due to possible conducted and
radiated disturbances. It is therefore not suitable for class B environments.
If class
A equipment causes radio disturbances, take appropriate measures to
eliminate them.

Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF and LAN
cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
●
Use
≤
3 m for the USB cable length or the USB cable delivered with the cali-
bration unit, if possible.
