The tool is designed to measure the real output
power of base station, to our suggest, connect a
20 dB attenuator at least before measuring to
avoid the damage to the Tester.

Reminder:
A

20dB attenuator

is recommended to

be connected and used

before

the measurement

is started.

Warning:
It will cause the damage to
the Tester if an attenuator is
not used before measuring
the output power.
