The Keysight U2751A is a USB modular switch matrix designed to establish flexible connection paths between multiple test instruments and various points on a device under test. This 4×8 two-wire matrix with 32 crosspoints operates at up to 45 MHz with -30 dB crosstalk, delivering maximum switching times of 4 ms. The module handles up to 42 V / 2 A in standalone operation, with channel resistance power loss limited to 6 W per module.
The U2751A connects via high-speed USB 2.0 (480 Mbps) using USBTMC-USB488 standard and communicates through a DB25 connector. It operates independently or integrates into the U2781A USB Modular Product Chassis for expanded multi-module configurations. Power consumption is +12 VDC at 2 A maximum.
