CSB Low Noise Bipolar Current Supply

CSB provides very low noise programmable current. It offers three independent channels of output current referenced to ground. Thanks to its internal galvanic isolation, it does not create a ground loop between the computer and the current sink. 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.
