1. 07 Keysight Advanced Power System N6900 and N7900 Series Power Supplies Brochure Properly powering on and off your DUT with the APS If you work with DUTs that have multiple power supply inputs such as satellite payloads you often need to properly sequence on or off each power supply at strictly repeatable times to prevent current surges and latch up conditions In addition to sequencing on or off each supply you may need to set the ramp rate of each supply at turn on or turn off to a particular rate These requirements add significant complexity to an ATE test system both in hardware and software The APS power supplies can help you overcome this test challenge by providing built in sequencing capability across APS mainframes or with Keysight s popular N6700 family of modular system power supplies Also the APS power supplies provide adjustable slew rate control at turn on or turn off These built in capabilities provide a clean low complexity way to properly power on or off your DUT during test Add power lexibility to your test system by paral leling multiple APS supplies Paralleling multiple power supplies together is a great way to add power flexibility to your test system The down side of paralleling power supplies together is typically you cannot get all the supplies to operate in the desired constant voltage CV or constant current CC mode For instance when trying to operate in CV mode with two parallel2.
