±20 V, ±2 A DC, 40 W PXI Source Measure Unit—The PXI‑4130 is a programmable source measure unit (SMU). It has a single isolated SMU channel that offers a four-quadrant output that incorporates remote (4‑wire) sense. With its five current ranges, it is ideal for transistor ch...
This article will discuss ways to combine multiple SMU channels (from multiple modules) to extend the voltage-current coverage for applications that require higher voltage or current levels. The following discussion assumes that PXI-4130 is used with APS-4100 auxiliary power supply. When combining ...
