Symmetric Supply with R&S® Power Supplies

Analog circuits like operational amplifiers often require a symmetric supply with supply ground, positive rail and negative rail. The supply ground is the reference for analog signals in the circuit.

The channels in R&S® multi-channel power supplies are galvanically completely floating against each other as well as against safety earth. This provides the maximum flexibility for connecting channels in parallel or in series to provide increased current or voltage output, or for split or symmetric supply.

This application note describes how to configure two outputs for a symmetric supply, providing both positive and negative rails.

The instructions apply also to both discontinued and future multi-channel models of R&S® power supplies.
