The LDX-3220 Precision Laser Diode Driver is a 200mA / 500mA microprocessor-based current source that offers a high stability, low noise output and integrated laser diode protection circuits. In addition to precision current control, the LDX-3220 Precision Laser Diode Driver is loaded with standard features such as dual current ranges, constant power control, fine/coarse set point control, four-wire forward voltage measurement, and external modulation capability. For automated testing applications in an R&D or production environment, remote operation is easily accomplished through the GPIB/IEEE-488 interface. For virtual instrument programming, LabVIEW instrument drivers are available.
