7.8. Verify Bluetooth BLE 5.0 Tx Performance
To measure the DUT BLE 5.0 Tx power and modulation index to check whether BLE Tx
performance fine or not. Bluetooth BLE 5.0 Tx criterion is shown as below. Below SPEC
is defined by using 5 dBm as target power at normal temperature 25 degree C. For vender’s
Tx verification, please adapt target power value as your own spec.
