Lianxun Instruments S2019C Four-Channel PXIe Plug-in Source Measure Unit Precision Power/Measurement Unit ±40 V, ±500 mA (DC), ±1 A (pulse)

Model：S2019C Country of Origin：China

Category：SMU Source Measure Unit

Overview：

Semight Instruments S2019C A compact, cost-effective four-channel PXIe source/measure unit (SMU) that simultaneously sources and measures voltage and current, delivering up to ±40 V and ±500 mA (DC) or ±1 A (pulsed). It supports standard SCPI commands for fast, easy migration of 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 DMM;
♦ 1 pA / 1 µV resolution: excellent measurement sensitivity;
♦ 1 MS/s ADC sampling rate: enables high-speed measurement, with fast setup and digitization rates for the arbitrary waveform generator (list sweep);
Extensive sweep capabilities

Channel【2】【3】	CH0 to CH3
Output power	Max. 4 W per channel, max. 8 W total for four channels
Overshoot	<±0.1% (typical, Normal, step from 10% to 90% of range, full-scale point, resistive load test)
Noise 10Hz-20MHz	6 V voltage source, 0.5 A resistive load, <3 mVrms

[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 has potentially hazardous high voltage (±42 V) output 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 to chassis ground or output LO), otherwise the instrument will be damaged
