SMM3000X Series
A precision four-quadrant Source Measure Unit that sources and measures voltage and current in one tightly-integrated instrument. Spanning ±210 V and ±3.03 A DC (±10.5 A pulse) at 31.8 W per channel, it resolves down to 10 fA and 100 nV with 6½-digit readback — ideal for characterising semiconductors, LEDs and laser diodes, sensors, materials and batteries. DC, pulse, sweep and list modes, 100,000 readings/s acquisition, a 5-inch capacitive touchscreen and SCPI over USB/LAN make it equally at home in R&D and automated production test, in single- or dual-channel versions.
Precision Source Measure Unit (SMU)
A precision four-quadrant Source Measure Unit that sources and measures voltage and current in one tightly-integrated instrument. Spanning ±210 V and ±3.03 A DC (±10.5 A pulse) at 31.8 W per channel, it resolves down to 10 fA and 100 nV with 6½-digit readback — ideal for characterising semiconductors, LEDs and laser diodes, sensors, materials and batteries. DC, pulse, sweep and list modes, 100,000 readings/s acquisition, a 5-inch capacitive touchscreen and SCPI over USB/LAN make it equally at home in R&D and automated production test, in single- or dual-channel versions.
Both models share the same platform, 5-inch touch interface and SCPI command set, so you choose on channel count — then add the triaxial adapters and GPIB control your fixtures need. siglent.eu is the official EU distributor, with stock, warranty and local support.

Features in depth
Source and measure, across four quadrants
A Source Measure Unit combines a precision programmable source and a high-resolution meter that track together. The SMM3000X can force a voltage and measure the resulting current — or force a current and measure the voltage — while sourcing or sinking power in any of the four quadrants, so it characterises active and passive devices a plain supply or meter cannot.
- Force V / measure I, or force I / measure V
- Four-quadrant operation — source or sink
- ±210 V, ±3.03 A DC, ±10.5 A pulse, 31.8 W per channel
- 0.015% + 225 µV voltage & 0.1% + 100 pA current accuracy
Femto-amp resolution for precision device test
With 10 fA current and 100 nV voltage resolution and 6½-digit readback, the SMM3000X resolves leakage currents and small signal levels that ordinary instruments miss — the basis for semiconductor, sensor and materials characterisation.
- 10 fA / 100 nV resolution, 6½-digit (2.1 M count)
- Linear & logarithmic sweeps, list mode (10 µs interval)
- Up to 100,000 readings/s, 100k-point time-stamped storage
- Single-channel (SMM3311X) or dual-channel (SMM3312X)
Rear panel, triaxial connections & remote
Triaxial outputs preserve the guarding needed for low-current measurement, and the standard USB/LAN interfaces make the SMM3000X easy to automate. Optional banana-to-triaxial adapters connect it to test fixtures and wafer probe stations.
- Triaxial force/sense outputs with guard
- USB & LAN (embedded web server) standard; SCPI
- Optional USB-GPIB adapter for GPIB buses
- Optional STC6-series banana-to-triaxial adapters

Frequently asked questions
An SMU combines a precision programmable voltage/current source with a high-resolution meter that operate together. It can force a voltage and measure current, or force a current and measure voltage, while sourcing or sinking power in all four quadrants — ideal for characterising devices such as semiconductors, LEDs and sensors.
The SMM3311X is a single-channel SMU and the SMM3312X is a dual-channel version; both share the same ±210 V, ±3.03 A DC (±10.5 A pulse), 31.8 W/channel performance and 10 fA / 100 nV resolution. Choose the dual-channel model when you need to source and measure two nodes at once.
Down to 10 fA of current and 100 nV of voltage, with 6½-digit (2,100,000-count) readback — fine enough for device leakage and small-signal characterisation.
The outputs are triaxial. The optional STC6-series banana-to-triaxial adapters (STC6P4W 4-wire/Kelvin, STC6P2W 2-wire with guard, STC6P2W-B 2-wire) connect the SMM3000X to test fixtures and wafer probe stations; a USB-GPIB adapter adds GPIB control.
Yes — USB and LAN with an embedded web server are standard, with full SCPI command support and optional GPIB via the USB-GPIB adapter, plus list/sweep modes and up to 100,000 readings/s for high-throughput test.
