Agilent 6620A Series Multiple-Output,
40-105 W DC Power Supplies, GPIB
Data Sheet
Speed and accuracy for test optimization
• Up to four fully isolated power supplies in a 3U package
• Dual-range outputs
• Fast, low-noise outputs
• Built-in measurements and advanced programmable features
• Protection features to ensure DUT safety
Two, three, or four isolated outputs are
integrated into one package, conserving rack space and GPIB addresses.
Most of the outputs also provide dual
ranges, for more current at lower
voltage levels. The outputs can be
connected in parallel or series to further increase the flexibility that these
products offer the system designer.
Programming is done using industry
standard SCPI commands. Test system
integration can be further simplified by
using the VXIplug&play drivers. These
power supplies help reduce test time
with fast up and down programming,
enhanced by an active downprogrammer
which can sink the full rated current.
