35-Channel, 0.25 A PXI Signal Insertion Switch Module—The PXI‑2515 is a multiplexer switch module that enables connectivity by routing high-speed digital I/O (DIO) signals between a device under test (DUT) and an NI high-speed DIO device or a parametric measurement device. You can use modules such as PXI Source Measure Units (SMUs) and PXI Digital Multimeters (DMMs) with high-speed digital devices. With the PXI‑2515, you can perform parametric tests on digital pins without external connectivity or impedance mismatch challenges.
