I've been using the Atmel Power Debugger to sort out power consumption issues on some µController based circuits... and have been pretty pleased. Unfortunately, it's limited to a maximum of 5.5 volts and I need to work on some circuits which are a little above that range, up to 18 V.
Can someone recommend a method and or off the shelf hardware to help me get going on DC power measurements in the 0-18 V range?
What are some options for logging power consumption over several hours... maybe as long as 24 hours to evaluate circuit / firmware performance?
A different post (How to Measure Power Consumption on Extremely Low Power Devices?) mentioned the µCurrent Gold Multimeter adapter to utilize with a multimeter, but it's out of stock.
Any suggestions would be greatly appreciated!
