CSBX Programmable Bipolar Current Supply

CSBX provides very low noise programmable current with both digital and analog controls. Thanks to galvanic isolation between digital and analog sides, it does not create a ground loop between the computer and the current source. It offers dc currents as well as very slow modulations of a few Hz. Thanks to its grounded output, it is easy to sum other currents or modulations with the output using a simple SMA tee. An additional output filter can be enabled to provide lower noise at frequencies above 100 Hz.
