Transmitter Output Power
15.1.2.1
Test Description
In this test the conducted RF output power of DA14680/681 range extender was measured.
15.1.2.2
Test Setup
The DA14680/681 range extender was mounted on a PRO-motherboard. In order to evaluate the TX
output power,
ble_external_host
firmware was used. Conducted transmitted output power was
measured by using the R&S
®
CBT Bluetooth
®
Tester. An RF cable assembly was connected to J3 RF
Switch connector (MM8130-2600 by Murata) and at the other end through an attenuator to the R&S
CBT Bluetooth Tester.
●
Bursts of 10 packets were transmitted by the DA14680/681.
●
The packet length was 255 and the pattern was “01010101”.
●
Three channels were recorded: channels 0, 19 and 39.
