Source/Monitor Unit (SMU)
Source/Monitor Unit (SMU)
The source/monitor unit (SMU) has the following three modes:
• voltage source and current monitor mode (V source and I monitor mode)
• current source and voltage monitor mode (I source and V monitor mode)
• source common mode
SMU can output constant or pulsed source. (Only one SMU can be set to pulsed
source.)
Figure 1-2 shows a simplified SMU circuit diagram.
