DC power supplies measure battery standby and sleep-mode currents

Agilent Technologies has introduced two modules for its Agilent N6700 Modular Power System family that deliver quick and accurate measurements of microamp current for a device under test (DUT).

For R&D engineers designing integrated circuits and electronic devices that run on batteries, these power supplies measure current consumption and its effect on battery run time. When used in automatic test equipment (ATE) systems, they give test engineers accurate measurements of microamp currents in milliseconds, allowing them to increase ATE system throughput.

Agilent's N6700 family of power supplies with microampere current measurement technology feature fast transient response at high currents and are capable of fast, accurate, low-level current measurements. The patented design does not induce voltage disturbances.

This technology, available as option 1UA to the N6760 Precision DC power modules, allows microampere current measurements to be made in a few milliseconds with only 100 nA of offset error, while still meeting transient response time of less than 50 microseconds for currents of 2 A.

N6760 Precision DC power modules are supported in the AN6705A DC power analyser for R&D and in the N6700 low-profile modular power system for ATE.
