Current Consumption
15.1.3.1
Test Setup
The board used in the test presented optimal RF performance. The integrated printed antenna was
used to perform the measurements.
The following instruments were used for the test:
●
Multimeter
●
3 V, 200 mA power source
●
Agilent N6705B DC Power Analyzer
The current profiles were evaluated using advertising demo firmware with embedded PA control.
During this test the Advertising, Connection and Extended Sleep modes were evaluated.
15.1.3.2
Advertising Mode
For this measurement the DUT was supplied by 3 V. FW was downloaded and the JTAG
programmer and then it was disconnected.
