Ion trap and precision experiments, STM/AFM and Nanoscience
are the main areas, in which our precision voltage sources are used. Here a
synoptic table of our versatile range of multichannel voltage sources.

|
|
Our BS Series devices provide precise and stable DC voltages up to +/-14V for biasing
purposes. Unlike DC power supplies, the outputs currents are limited to small values,
and the outputs are optimized for high short and long term stability, low noise and
low temperature drift. The device is housed in a standard 19-inch rack-mount case.
User control of the device can be accomplished by PC control programs, utilizing a
standard USB connection (USB 2.0 compatible). The programmed voltages and measured
output currents are displayed on the front LCD display. Read more in the

The new UM 1-5/1-14 LN on the left is the latest family member of our series of 3-channel ultra high precision voltage sources.
It features a further improved temperature-coefficient and even less voltage fluctuations on a 10E-8 level.
The device represents the preferential choice for applications needing up to 3 precision voltage outputs
in the +/-14V range and is currently unrivalled in its class. Data Sheet UM-series (pdf, 2 MB)
The UM 1-5b on the right is a bipolar ultra high precision 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.

Our new QUAD 1-10 rotating wall drive is designed to create a rotating dipole or quadrupole electrical
field inside a Penning Ion Trap. The resulting electrodynamical "rotating wall" enables fast
compression of big ion clouds after loaded into the trap. The QUAD 1-10
represents a tool to handle a wide range of ions/plasma rotation frequencies with respect to this novel
application.

The QUAD 1-5b rotating wall drive is a Precision Wideband Phase Shifter in combination
with output amplifiers, dedicated for compression of non-neutral plasmas in Ion
Traps. It provides 4 phase shifted outputs with up to 20Vpp Amplitude.
It operates in a wide frequency range from 100kHz to 5MHz. Small
mismatches of amplitude and phase are provided over the entire frequency range.

DC 1-10ref is a fixed voltage reference, providing an 1.000000V and an 10.000000 V output.
Calibrated to a Josephson-Junction-based standard it serves a high precision seondary
voltage standard and laboratory reference. Long term and temperature drifts are in the
ppm-range and rival much more expensive reference solutions. Typical applications are
calibrations of other devices (e.g. multimeters) and trap based precision experiments.
