Bluetooth headset radiation testing
1: TSA5G35 will be connected
with 2.4G whip antenna and
close to the Bluetooth headset
2: Pairing the Bluetooth with the
mobile phone, and make phone
call, the Bluetooth shall pick up
the call to setup audio link.

Bluetooth Headset radiation testing
TSA5G35 parameter setting:
Because the Bluetooth
working at frequency hopping.
It is wait a little long time to
get test result

Bluetooth Headset radiation testing
The MAX curve and MAX, AVE and density image, Bluetooth will detect wifi
signal to avoid hopping at wifi band.
