There is a growing need for battery current drain testing in hardware development, software development, design validation and manufacturing of wireless devices. Most wireless devices spend the majority of its operating life time in an idle or sleep mode and operate in short bursts of activity to conserve power. This causes the battery current drain to go from nA's and uA's up to Amps of current. This wide dynamic range of current is very difficult to measure using traditional fixed range current measurement techniques such as the use of current probes and shunts.
 

In the past, maximizing the battery life of your devices was challenging because dynamic current was difficult to measure. Now, two new source measurement unit (SMU) modules for Agilent's N6705B DC power analyzer eliminate the challenges of measuring dynamic currents with a feature called seamless measurement ranging. Seamless measurement ranging lets you measure dynamic currents precisely without glitches or disruptions. As the current drawn by your DUT changes, the new N6781A and N6782A SMUs automatically detect which current measurement range will return the most precise measurement and change to that range instantaneously. This ultrafast ranging gives you an unprecedented effective vertical resolution of 28 bits, which offers unrivaled insights into your DUT's power consumption. You can now see your complete current waveform, from nanoamps to amps, in one pass and one picture.
 

This webcast will go on to discuss an Agilent exclusive feature called "seamless measurement ranging" which overcomes the limitations of traditional techniques for battery current drain testing. "Seamless measurement ranging" is a patented technology that accurately measures battery current drain from uA to Amps in a single sweep, while at the same time ensuring the highest level of measurement accuracy at each portion of the measurement waveform.
