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)

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).
