Source Measure Units (SMUs) combine the precision of a digital multimeter with the control of a power supply, allowing you to source and measure voltage or current simultaneously in one instrument. They’re essential for laboratory, R&D, and production environments where accuracy, repeatability, and traceability are critical.

At Vicom, we partner exclusively with Tektronix and Keithley to supply professional-grade Source Measure Units across Australia and New Zealand, backed by local expertise, calibration, and long-term support.

SMUs are used wherever precise sourcing and measurement are required. Common applications include: – Semiconductor and device characterisation – Testing diodes, MOSFETs, and power devices with sub-microamp and microvolt precision for IV sweeps and leakage measurements. – Battery and energy storage testing – Cycling cells, measuring capacity, and evaluating internal resistance with high repeatability and integrated safety controls. – Sensor development – Characterising optical, magnetic, pressure, and temperature sensors with stable excitation and ultra-sensitive measurements. – Materials research – Measuring resistivity and contact properties over wide dynamic ranges. Across defence, communications, manufacturing, and university research, Vicom customers use Tektronix and Keithley SMUs to validate designs, accelerate automation, and ensure measurement confidence.

Keithley, part of Tektronix, pioneered the Source Measure Unit and remains the global leader in precision sourcing and measurement. Keithley SMUs provide exceptional accuracy, wide dynamic ranges, and advanced programmability suited for both R&D and automated test systems.

Tektronix complements this leadership with integrated software, automation frameworks, and calibration solutions that ensure efficient workflows across your lab. Whether for semiconductor characterisation, battery testing, or materials research, Keithley SMUs deliver unmatched performance, reliability, and total cost-of-ownership advantages.
