BE214x – Voltage Source: ±12V ±15mA, 4 output channels
Four independent ±12V / ±15mA voltage sources with 21-bit resolution and <5 µV peak-to-peak noise.
Designed for ultra-low-noise and high-stability applications.
Description
The BE2141 module integrates four independent voltage sources sharing the same isolated ground.
Each channel provides 4-quadrant DC operation and 6½-digit resolution, combining high accuracy and very low noise.
Two output ranges are available: ±1.2V and ±12V, with a ±15mA current limit.
Noise is exceptionally low — down to 5 µV peak-to-peak (<1 µV RMS) — with a voltage noise density below 3 nV/√Hz and no spike visible up to 3 kHz.
The source achieves few ppm stability within 24 hours and a typical settling time of 45 ms.
The BE2141 offers 21-bit resolution, 4-wire sensing, and programmable waveforms (exponential, ramp, staircase, steps) with input/output triggers on SMB connectors.
Each output and sense connection uses SMA connectors.
The module can also be upgraded to the BE2142 version, which adds current measurement capability.
It operates within ±150V isolation, features no transient on power on/off, and ensures no crosstalk between sources.
