Overview

A compact 40-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

  • 40 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.
