UM – a voltage source with 10-8 level stability

The UM is worldwide unrivaled as a 3-channel ultra-high precision voltage source for its proposed voltage ranges, typically ±14 V. It features an extremely low-temperature dependency of 10-6 ΔV/V per Kelvin and temporal voltage fluctuations of less than 10-7 ΔV/V per minute.

This unique combination of resolution, stability, and long-term drift makes it ideal for quantum computing and high-precision ion trap-based spectrometry. The UM is currently used, for instance, in virtually all high-precision ion trap spectroscopy experiments globally.

The voltage range of the device can be customised: According to your application, you would typically limit the maximum voltage in order to tap the full potential of the 25 bit resolution.

Key Features
standard voltage range: ±14 V, customisable to e.g. ±30 V
3 channels each resolved with 25 bit (0.1 ppm resolution)
10 ppm base accuracy
fluctuations on 10-8 level
