Hi, based on some code from Omprakash Gnawali we built a DC measurement tool (which is probably similar to the one in rfx).
It tracks the time the radio is on and reports this over the serial. We used it in the ORW paper (IPSN 2012) and some others. Have a look at: https://github.com/olafland/orw/blob/master/tinyos/tos/chips/cc2420/dc/DutyCycleP.nc (If needed, one can probably build a similar tools for the processor.)
