Overview
The 7144-02-04 MultiSource is a compact, mutli-channel laser diode driver for lower power applications. Excellent accuracy, great long term stability, and the hardware protection features you'd expect from an Arroyo Instruments product.
Standard Computer Interfaces
The MultiSource includes both Ethernet and USB computer interfaces, allowing for quick and easy connection to a PC for remote operation. In addition, the command set is compatible with ILX and Newport controllers, allowing you to leverage any existing software you may have already developed.
Simple Local Control
While intended to be primarily operated from a PC, the display on the MultiSource allows you to locally monitor status and turn channels on and off.
