±200 V, 1 A Precision System PXI Source Measure Unit—The PXIe‑4137 is ideal for a broad range of applications including manufacturing test; board-level test; lab characterization with devices such as ICs, power management integrated circuits (PMICs), and radio frequency integrated circuits (RFICs); and discrete devices including LEDs and optical transceivers. The PXIe‑4137 features 4-quadrant operation. The PXIe‑4137 is a hardware-timed instrument with a high-speed sequencing engine for synchronizing acquisitions between multiple SMUs. The module supports direct DMA streaming between the host PC and SMU, so you can stream large waveforms and measurement data at the full update rate and sample rate of the instrument. You can custom-tune the PXIe‑4137 response to any load to achieve optimum responses with maximum stability and minimum transients.
