– 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
Give particular attention to the following aspects when handling the components
of the R&S
NRPM OTA power measurement solution.
For information on the options for connecting the sensor modules and test
setups for the measurements, see
Chapter 6, "Setting up a measurement"
To prevent antenna damage
Damage is most likely to occur when you connect or disconnect an antenna mod-
ules.
1.
NOTICE!
Electrostatic discharge can quickly and imperceptibly damage or
destroy the electrostatic sensitive antenna modules.
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
2.
NOTICE!
If you touch the PCB (printed circuit board) of the antenna module, it
can bend and thus lead to measurement inaccuracies.
Always hold the antenna modules by the housing. Take care not to touch the
exposed top or bottom of the antenna module PCB.
