Save Time and Reduce Errors with Computer-Controlled Solid-State Connections

The Precision 4164 Switch Matrix System is a reliable solid-state switch matrix system in a compact rack-mountable or benchtop device providing computer-controlled connections between any input and any output. Connect between 64 input and 64 output channels with 4,096 cross points.

Save time and reduce errors on your switch system setups with the easy to use spreadsheet style Graphical User Interface. Save configurations and download them to your switch system over the network—and your tests are ready to go. Program the switch from your application via the high-level Ethernet interface. Edit configurations offline in Excel.

With system health monitoring, fault diagnostics, and exhaustive self-tests, you can have confidence in the integrity of the 4164 system. Option F provides Go/No-Go test feature and Factory Acceptance Tests (FAT) routines.

The built-in Go/No-Go test feature automatically verifies run-time setup by checking each programmed connection using a direct input-to-output measurement. The 4164 FAT routines measure switch system parametrics, including gain, crosstalk and open/short, in situ to verify performance and provides full test reports.

When power is applied to the system, the system provides unidirectional signal paths from input to output channels. When power is removed, switch settings are retained in nonvolatile memory and restored at power up. Balanced differential input buffers reduce noise susceptibility and correctly reference the signal inputs to their corresponding ground. Ground sensing output buffers reduce power-line hum when driving single-ended loads.
