Introduction

The U2751A USB modular switch matrix offers a high quality, low cost switching solution for automated test. It can operate as a standalone or modular unit when used with the U2781A USB modular instrument chassis.

The U2751A is a compact 4×8, two-wire modular switch matrix which is controlled remotely over a USB interface via the Agilent Measurement Manager software. The U2751A can also be programmed using the provided drivers or via SCPI commands.

The U2751A has the following features.

32 two-wire cross-points organized in a 4 rows by 8 columns configuration

any combination of rows and columns can be connected at a time. Multiple channels can be closed at the same time

relay cycle counter

The U2751A offers you the most flexible connection path between your device under test (DUT) and your test equipment, allowing different instruments to be connected to multiple points on your DUT at the same time.

Using the Agilent Measurement Manager, you can instruct the matrix to make or break any of the 32 row-column intersections over the USB interface. More details will be covered in the Agilent Measurement Manager help file.
