PCX-7401 Pulsed Precision Current Source
Precision Pulse Control
The PCX-7401 offers the capability of providing both pulsed and bias outputs. A modern internal trigger source is capable of two modes of operation: duty cycle and single shot. External trigger is available for additional flexibility.
Low Inductance Output Cable
Connection to the laser diode is made through an innovative low-inductance stripline cable, designed to preserve the fidelity of high-speed current pulses. The output connector is interlocked so that the PCX-7401 is disabled when the cable is removed.
Output Protection
The PCX-7401 features advanced circuitry to protect both the laser diode and instrument. At turn on, and at any time the output is not enabled, the PCX-7401’s output is electronically shorted to ground, ensuring that no current flows through the laser diode. Safety features of the instrument include a separate output enable key switch, an output cable safety interlock, and an external enable control signal.
Ease of Setup and Operation
The PCX-7401 may be operated through the intuitive front panel controls. The color LCD provides immediate visual confirmation of all operating parameters. Store and Recall User Settings
All system configurations may be stored and recalled in the internal non-volatile memory.
Complete System Integration
Automated applications can utilize RS-232, USB, or Ethernet computer interfaces.

Notes
* Current accuracy +/- 1 mA for output currents with pulse frequency below 100 kHz. Current accuracy between 100 kHz and 1 MHz is: +0 mA / –X mA Where X =((Output frequency in Hz) * (current setpoint in A) / 31,000)
** In single shot mode bias is a fixed pulsewidth before and after the main pulsewidth, as shown above.
