Overview
The Nicslab XDAC B-120 (SKU XDAC-120MUB-R4G8) is a compact 120-channel source measurement system. Each channel independently sources and measures voltage or current, with bipolar 4-quadrant outputs that can both source and sink current.
The system is intended for low-power applications, from simple electronic circuits to complex photonic integrated circuits. Each channel operates in Constant Current (CC) or Constant Voltage (CV) mode, and the voltage ranges are selectable in software at 16-bit resolution.
Software and control
The instrument is controlled through a graphical user interface or with SCPI commands from Python, MATLAB, LabVIEW or C#. It connects over Ethernet, and a USB-to-Ethernet adaptor is included.
Basic and Premium versions
The Basic version runs on a fixed ±16 V output range. The Premium version adds software-selectable sub-ranges (±2.5 V, ±5 V, ±10 V) for higher-resolution operation. It also adds configuration save/upload, CC/CV sequence automation, data recording and per-channel short-circuit protection.
