2.3.3 Current Consumption Measurements

For each of the measurements, the XDS110 debugger jumpers are initially kept on the LAUNCHXL-CC1352P board. The relevant application software is then flashed on the CC1352 using the CCS IDE. Once completed, the board is is disconnected from the PC device and all the jumpers on the Launchpad are removed except for the XDS110 GND, 3.3V, RXD<< and XDS110 Power jumpers as these are crucial for the functionality of the EnergyTrace™. The board is then reconnected to the PC device using the USB micro and EnergyTrace™ is started.

Each reported current value is the average of 10 measurements on four boards, for a total of 40 measurements and is the average of a 30 sec time window run of the program specified. All measurements were done in a room temperature environment.

The application note uses the following software and hardware to find the current consumption of the Sensor Controller:
