Ultrastable bipolar voltage source UM 1-5b

The UM 1-5b is an ultra high precision bipolar  voltage source. It offers three independent channels, each resolved with 25Bit, +/-14V and +/-3.5V range. It is the first device on the market having three independent voltage channels with better 0.1ppm resolution and stability. It shows an unrivalled combination of resolution, stability and long term drift, making it ideal for  quantum computing and high precision ion trap based spectrometry.
It's e.g. in use at the University of Mainz, Department of Physics in the  g-factor proton experiment and the  g-factor calcium experiment.
