BS/BSA – Precision DC Source

Our BS/BSA series multichannel supplies provide precise and low noise DC voltages up to +/-40 V on a ppm level of stability.

A short response time of a few milliseconds and a high stability allow for
✔ fast and precise qubit biasing in quantum computing
✔ precision experiments with ion traps
✔ reliable usage in source-meter applications with automatic test equipment (ATE)

Key Features
voltage range bipolar: -0.1 V .. +0.1 V up to -40 V .. +40 V
number of channels: 2 up to 16 (32 channels in preparation)
programming resolution: 16-bit (model BS) or 19-bit (model BSA)
absolute accuracy: better than 250 ppm
short term fluctuations as root mean square values (rms): 0.3 ppm in 1 min / 0.8 ppm in 1 hour / 2.6 ppm in 24 hours
Tips and tricks

1. Improve response time and communication latency of the device
Try setting the latency timer of USB driver to 1 ms (default: 16 ms). See these instructions (pdf).
