Nicslab XPOW U-8
An 8-channel, unipolar SMU designed for compact, low-power automated testing.
Quantity
Overview
A compact 8-channel unipolar source measurement system supporting independent voltage/current sourcing and measurement per channel (CCvCV configuration), or independent voltage sourcing with voltage/current measurement per channel (CV Only configuration). 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)
Two control configurations are available: CC+CV — Constant Current (0–300 mA) and Constant Voltage (0–34 V); or CV Only — Constant Voltage (CV, 0–34 V) with current determined by the connected load and an unregulated maximum compliance of 300 mA.
Software-selectable voltage ranges with 16-bit resolution: 0–5 V, 0–10 V, 0–20 V, 0–34 V
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#)
USB connectivity (USB 2.0 minimum; USB 3.0 Type-B cable included)
GPIO header for external control and monitoring
Optional Premium features: configuration save/upload, CV (or CC/CV) sequence automation, data recording, per-channel voltage/current threshold limits, notes
CE and RoHS3 (2015/863) compliant
Note: The Basic version operates on a fixed 0–34 V output range. Software-selectable voltage sub-ranges (0–5 V / 0–10 V / 0–20 V) are a Premium feature — see Basic vs. Premium Features below.
