662x multiple-output DC power supplies integrate
Agilent 662x multiple-output DC power supplies integrate two, three, or four isolated outputs into one package, conserving rack space and GPIB addresses. Most of the outputs also provide dual ranges for more current at lower voltage levels. Connect these outputs in parallel or series to further increase their flexibility. Test throughput is increased with an active down-programmer that can sink full-rated current. The precision models have up to 1µA current resolution.
