Application-specific modules for battery test, mobile device manufacturing

Two application-specific modules have been introduced for use with the Agilent Technologies N6700 modular power system (MPS) family. The N6783A-MFG module provides sourcing and measurement capabilities designed to meet the challenges of battery-powered (mobile) device manufacturing. The N6783A-BAT module proivdes basic two-quadrant operation for charging and discharging batteries for the design of a mobile device.
 
At the beginning stages of design, engineers can qualify the battery for use in the final product by using the battery charge/discharge module. Throughout the design, they can use the N6781A source measure unit to perform battery drain analysis. When the design is complete and moves to manufacturing, the mobile communications DC power module can be used in the final test system.
 
The Agilent N6783A-MFG module has features specifically for testing mobile devices in manufacturing. Its voltage transient response ensures that a stable output voltage is maintained at the device under test during load transients. This improves system throughput by eliminating inadvertent device shutdowns that occur if the voltage is allowed to drop too low, such as when a non-specialized power supply is used.
 
The built-in digitizer also maximizes throughput by providing flexible measurements that are customizable so that the desired balance between speed and accuracy can be achieved.

The N6783A-MFG module is a follow-on product to the Agilent 66300 mobile communications DC source series but has twice the output density (up to four outputs in 1 U) and modern I/O (USB, LAN and GPIB are standard).
 
The N6783A-BAT module is a basic two-quadrant DC module designed to enable mobile device designers to validate the battery to be used in the device being designed. Battery validation requires charging and discharging the battery while measuring voltage and current to ensure it meets the desired specifications.
 
Its two-quadrant operation allows it to act as a power supply to charge the battery or as an electronic load to discharge the battery. It has a built-in digitizing measurement system that provides  accurate measurements over the short and long term.

The N6783A-BAT can also be used to condition batteries for test in mobile devices by charging or discharging the battery to a specific level to see how the device performs under specific conditions. It can be used for battery charge/discharge only. For advanced battery drain analysis and battery emulation, the N6781A two-quadrant SMU for battery drain analysis should be used.
 
The N6783A-MFG and N6783A-BAT are a part of the N6700 modular power system family, which consists of the N6700 low-profile mainframes for automated test environments and the N6705 DC power analyzer mainframe for R&D. The product family has four mainframes and over 25 DC power modules, providing a complete spectrum of solutions, from R&D through design validation and manufacturing.
