Lianxun Instruments S0342C 4-channel PXIe plug-in source meter precision power supply/measurement unit ±30 V, ±500 mA (DC/pulse)

Model：S0342C Country of Origin：China

Category：SMU Source Measure Unit

Overview：

Semight Instruments S0342C is a compact, cost-effective four-channel PXIe source/measure unit (SMU) capable of sourcing and measuring voltage and current simultaneously, with a maximum output of ±30 V and ±500 mA (DC/pulse). It supports conventional SMU SCPI commands for quick and easy migration of existing test code, is compatible with mainstream PXIe chassis, and supports multi-card synchronization for integration into production test systems, improving test throughput and reducing cost.

Features and Benefits

5 functions in one
Voltage source
Current source
Ammeter
Voltmeter
Electronic load
Quadrants I and III operate as a source: the actual polarity of the V/I output follows the source setting;
Quadrants II and IV operate as a load: CC and CV work together; when used as a load, the load setting polarity is opposite to the source polarity;
Capable of testing a wide range of devices
Capture more measurement data
♦ 6-digit resolution: accuracy comparable to a 6½-digit multimeter;
♦ 100 pA / 60 µV resolution: excellent measurement sensitivity;
♦ 500 kSa/s sampling rate: high-speed measurement with fast setup/digitizing rate for arbitrary waveform generation (list sweep);
Extensive sweep capabilities

[1] Accuracy calculation example: to test the accuracy of a 1 V output on the 6 V range, the tolerance is:

[2] All channel outputs are electrically isolated from earth ground, but the outputs of all channels share a common ground (LO)

[3] This instrument outputs potentially hazardous high voltage (±31.5 V) to the HI/Sense HI/Guard terminals. To prevent electric shock, relevant safety precautions must be taken before power-on. Do not connect the Guard terminal to any output, including shorting it to chassis ground or output LO, otherwise the instrument will be damaged.
