2.3.1.2 Active Current Measurement

To measure active current in a profile form, TI recommends utilizing a 0.1Ω 0603 sized resistor, and measuring the differential voltage across the resistor. This can be done using a voltmeter or an oscilloscope for measuring the current profile for both power supplies (3.3V or 1.8V).

The jumper J15 shunt should be removed and the 0.01Ω resistor is populated in parallel to measure the active currents on the 1.8V supply (see Figure 2-8). Similar operation with jumper J16 and 3.3V supply.
