Applications
Built for device characterisation
Nanoampere resolution and 4-quadrant source/sink on both channels, measured in the miniSMU app and shown here as it appears on screen.

Solar cells & photodiodes
J-V sweep with fill factor, PCE, Voc and Jsc extracted automatically.

Transistors
Dual channels drive gate and drain for output and transfer curves.

Batteries & stability
Long-running logging and MPP tracking with CSV export.
Also used for LEDs, organic & perovskite photodiodes, electrochemical and printed transistors, and sensor characterisation.
Capabilities
Capabilities
2 channels
Independent SMU channels
Full 4-quadrant sourcing and sinking on both channels. Drive a transistor’s gate and drain from a single instrument.
V & I sourcing
A true current source
Drive a fixed current and measure voltage. Ideal for LED stability, battery cycling, and sensor biasing. Most SMUs under $4,000 can only source voltage.
±12 V · ±180 mA
Wide measurement range
Source and sink voltage and current in all four quadrants, per channel.
±15 nA
Low-current accuracy
Five current ranges down to 500 nA full-scale resolve nanoamp-level leakage and dark currents.
24-bit ADC
High-resolution acquisition
24-bit delta-sigma conversion with adjustable oversampling lets you trade speed for noise floor to suit each measurement.
Auto-ranging
Seamless range switching
Current ranges switch automatically mid-sweep without disturbing your measurement.
V & I limits
Built-in device protection
Programmable voltage and current compliance clamp the output automatically, so delicate devices survive an entire sweep unattended.
USB-C + Wi-Fi
Bench or remote
Wired USB-C, or 2.4 GHz Wi-Fi for measurements anywhere in the lab.
SCPI
Automation-ready
Official Python and LabVIEW libraries, a dedicated SweepMe! driver, and an easy SCPI-style command set.
2-wire & 4-wire
True 4-wire Kelvin sensing
Use both miniSMU channels together to eliminate contact and lead resistance measurement errors, with true force/sense separation at each terminal of the device under test. Essential for accurate solar cell fill factor, PCE, and low-resistance device characterisation. Standard 2-wire mode is also supported.
Software
