The Ossila Source Measure Unit P2005A2 is a compact dual channel instrument for current-voltage (I-V) characterization of electronic devices. It combines four instruments on one board: two source measure units that apply a voltage while sensing current and voltage, plus two precision voltage sense channels. A general-purpose shutter/trigger BNC can send or receive control signals to coordinate with other equipment.
Each SMU sources within ±10 V and offers five current ranges, from ±200 mA down to ±20 µA with 0.1 nA resolution on the lowest range, so both large and very small currents can be measured. Output voltage is read directly at the BNC to account for load effects such as short circuits or low impedance. Positive and negative voltages are handled without resetting the setup.
The unit measures 185 mm x 125 mm x 55 mm and connects via USB or Ethernet, allowing several units to run together. Free Front Panel software controls every channel independently and saves data as .csv or .txt files, while languages such as Python, LabVIEW, MATLAB, Java and C/C++ can be used for custom control.
- Characterizing LEDs and OLEDs through I-V measurements.
- Recording solar cell I-V curves and running stability or lifetime measurements.
- Measuring transistor properties such as current gain.
- Measuring battery discharge rates using the V Sense channels.
- Determining material conductivity, leakage currents and four-point probe sheet resistance.
