0.4 m, PXIe-4135 GND/LO/LO SENSE Daisy-Chain, Braided Low-Leakage Cable for SMU—The SH3M-FL helps you connect the GND, LO, and LO SENSE terminals of a PXIe-4135 PXI Source Measure Unit (SMU) together, and the flying lead cable helps you daisy-chain multiple PXIe-4135 SMUs together. Daisy-chaining the PXIe-4135 SMUs allows the modules to share a common LO and reduces the number of SMU LO cables that need to be connected to the interface board or device under test (DUT).
