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.
