7144 SERIES FEATURES

The 7144 Series MultiSource Multi-Channel Laser Diode Driver is designed for applications requiring a large number channels in a cost-effective and compact solution. The MultiSource is an excellent building block for system applications such as device burn-in and characterization. Built with the performance you would expect from an Arroyo Instruments product, and both Ethernet and USB connectivity, you can quickly and confidently get your system operational.

OVERLAPPING LASER PROTECTION

Including safety interlock, ESD protection, hardware limits for current & voltage, soft power-on, and intermittent contact safeguards.

MULTIPLE OPERATING MODES

Choose from:

  • Constant Current
  • Constant Power
  • Constant Voltage

REMOTE VOLTAGE SENSING

Supports an extra pair of sensing wires to measure the operating voltage of your laser diode or LED.

ANALOG MODULATION (OPTIONAL)

Bandwidths up to 100 kHz.

ETHERNET INTERFACE

The built-in Ethernet interface allows the 7144 to be easily accessed via a network and integrated into larger system applications.

SIMPLE USER INTERFACE

Operational summary and individual channel information on an easy-to-read VFD display.
