Nicslab XDAC U-8
An 8-channel SMU with 16-bit resolution, unipolar outputs, and USB/Ethernet connectivity.
Quantity
Overview
A compact 8-channel unipolar source measurement system supporting independent voltage/current sourcing and measurement per channel. Designed for low-power applications ranging from simple electronic circuits to complex photonic integrated circuits.
Key Features
8 independently controlled channels
Unipolar output — single-quadrant sourcing (0 to 34 V, 0 to 300 mA)
Two operating modes: Constant Current (CC, 0 – 300 mA) and Constant Voltage (CV, 0 – 34 V)
Software-selectable voltage ranges with 16-bit resolution: 0–5 V, 0–10 V, 0–20 V, 0–34 V
Software-selectable current ranges with 16-bit resolution: 0–300 mA down to 0–3.125 mA
Real-time voltage reading with 0.15–0.6 mV resolution (range-dependent) and current reading with 10 µA resolution (range-dependent).
Control via intuitive GUI or SCPI commands (Python, MATLAB, LabVIEW, C#)
Ethernet connectivity (USB-to-Ethernet adaptor included)
Optional Premium features: configuration save/upload, CC/CV sequence automation, data recording, per-channel threshold and short-circuit protection
CE and RoHS3 (2015/863) compliant
Note: The Basic version operates on a fixed 0–34 V / 0–300 mA output range. Software-selectable sub-ranges (0–5 V / 0–10 V / 0–20 V and 0–200 mA down to 0–3.125 mA) are a Premium feature — see Basic vs. Premium Features below.
