Hi David, I use a high-precision 1 Ohm or 10 Ohm resistor connected in series between the mote and a laboratory power supply set to 3V. I then measure the voltage over the resistor with a digital oscilloscope. This allows me to sample the power consumption at a high frequency and thus distinguish between different phases of operation (radio turning on vs. listening vs. actually sending data).
