Short Description
The BE2142 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 BE21412offers 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 has current measurement capability.
It operates within ±150V isolation, features no transient on power on/off, and ensures no crosstalk between sources.
