6.2.4 Procedure

  1. Modifications for each board
    1. For CC3100Boosterpack: Remove jumper J6, Connect at Jumper J10, Pin_3.2 for GND.
    2. For CC3200LaunchPad: Remove resistor R62 across jumper J12 and also jumper J12.
  2. Connect external supply to the pin, which connects to device(on other pin we can measure 3.3V which is coming from board supply).
  3. Connect current probe to the positive supply wire and make sure current direction in the wire and arrow on the current probe are in same direction.
  4. Start executing the code and measure the active currents on the oscilloscope.
    1. To measure the charge of a profile, place the cursors to limit the profile and use “math” function to perform integral over time. The result will be the total profile charge in [Coulombs] in between the cursors.
    2. To measure the peak current of transmit (TX) and receive (RX) modes use the “Y” axis cursors.
