SMU

A Source Measure Unit (SMU for short) or Source Meter is a combination of a bipolar power supply, current meter and voltage meter all rolled into one instrument. In a testing system, the SourceMeter is indispensable when you need to measure DC current-voltage properties (I-V, V-I, I-R, V-R) or parameters. Applications are: testing semiconductor components and integrated circuits, solar cells and optoelectronic components such as laser diodes and LEDs. The SourceMeter can also measure the power consumption of circuits and modules.
