S0342C – Semight Instruments 4-Channel PXIe Precision SMU
The S0342C Precision source meter is compact and cost-effective 4-Channel PXIe Source/Measure Units (SMUs) with the capability to source and measure both voltage and current. They have Maximum ±30 V, ± 500 mA DC/Pulsed sourcing capability, supports conventional SMU SCPI commands for easy test code migration. Support Most of standards PXIe chassis, support multi-card synchronization, these features improve efficiency and lower the cost of ownership when integrating the SMUs into systems for production test.

Electronic load


- Three quadrants as the source: the actual polarity of output V / I follows the source setting;
- The four quadrants are loads: CC and CV cooperate. When the load is used, the polarity of the load setting is opposite to the source polarity;
Can test various equipment
