15.2.1
Maximum Output Power and Antenna Gain (Transmitter)
15.2.1.1
Test Specification
For systems using digital modulation in the 2400 MHz to 2483.5 MHz band: 1 W (30 dBm).
The EIRP shall not exceed 4 W (36 dBm) (Canada).
15.2.1.2
Test Setup
The DA14680/681 range extender was mounted on a PRO-mb Development Board. In order to
evaluate the maximum output power, the
SDK RF_Tool_CLI
was used. The boards under test were
set into continuous wave modulation transmit mode, using the following command:
ble_txstream \<FREQUENCY_MHz\> \<POWER\> \<PAYLOAD_TYPE\>
.
An RF cable was connected to the J3 RF Switch connector (MM8130-2600 by Murata) and at the
other end to the spectrum analyzer. Three channels were tested: channels 0, 19 and 39.
15.2.1.3
Test Results
The maximum peak conducted power was measured using the method according to point 9.1.1 of
Guidance for Performing Compliance Measurements on Digital Transmission Systems (DTS)
operating under 15.247.
Maximum output power: see next plots.
Maximum declared antenna gain: 0 dBi.
