CMicrotek is advancing the state of the art in current measurement instruments with the µPower Analyzer
and µCurrent ProbeTM. As the number
and variety of battery powered portable products have exploded over the past decade, an engineer’s ability to measure the power used by a
device has not kept pace. The traditional approach of measuring current with an oscilloscope worked for many decades because the power consumption level of most
circuits remained relatively steady regardless of the activity level of the product. Today’s battery powered products with wireless radios
have current levels that can be 100,000 times higher when the radio is active compared to when the product is in sleep mode. The traditional
approach has many issues with such wide ranging currents. The power management schemes used in today’s products also create complex current
waveforms that make it nearly impossible to accurately estimate power consumption over time based on simple current measurements. A simple
battery drain test can give you an idea of battery life but you have to be able to analyze the current waveforms in order to make improvements.
Inaccurate current measurements and power calculations are not just a problem for engineers, they can have significant business related
consequences. Worst case they can cause a product to be a complete market failure, best case a company can waste weeks and thousands of dollars
in engineering resources trying to fix a non-existent problem. Our specialized data acquisition products can help you avoid these
situations by giving you much more accurate measurements in much less time than the outdated traditional methods.
If you are looking for the µCurrent multimeter adapter from Dave Jones, you can find it
here on Dave's EEVblog, it's a good solution for
low-current readings with a multimeter.
