Our BS/BSA series multichannel supplies provide precise and low noise DC voltages up to +/-50 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 -50 V .. +50 V - number of channels:
2 up to 16 (32 channels in preparation, cf. MS preview below) - programming resolution:
16 bit (model BS) or 19/20 bit (model BSA) - absolute accuracy:
better then 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 for BS/BSA devices
- 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).
Preview: MS Series – Ultra High Stability Current Source (on request)
Our new modular MS series adds a high-precision multichannel current source to our product range, designed specifically for superconducting qubit biasing and cryogenic electronics. It had been developed for the qBriqs quantum technology project.
- 32 fully galvanically isolated channels — no common ground, minimal interference
- 20-bit resolution over an output range of 0 to 10 mA
- Ultra-stable outputs — typical short-term fluctuation below 1 ppm rms, temperature drift ~5 ppm/K
- Response time of a few milliseconds, suited for fast qubit biasing
Each channel is completely isolated from all others (typically 40 MOhm between channels), reliably eliminating ground loops and improving coherence times in quantum computing setups. Control is via USB using simple ASCII commands, compatible with Python, C++, LabVIEW and others.
