Product Description

Precision Pulse Control

The PCX-7500 is an air-cooled, high power current source designed to drive laser diodes, bars, and arrays. The output current can be set from 10 A to 450 A, compliance voltage is variable. The pulse width is adjustable between 4 µs to 5,000 µs, with a frequency of 8 Hz to 10,000 Hz.

Ease of Setup and Operation

The PCX-7500 may be operated through its intuitive front panel controls. The color QVGA LCD provides immediate visual confirmation of all operating parameters, including pulsed current set points, internal trigger pulse width, internal trigger frequency, and error/fault messages.

Complete System Integration

For automated applications, complete control of the instrument is provided through RS-232, USB and Ethernet computer interfaces. Up to four system configurations may be stored in internal non-volatile memory, providing instant recall of frequently-used configurations.

Low Inductance Output Cable

The laser diode is connected to the PCX-7500 through a low impedance strip line cable, designed to preserve the fidelity of high-speed current pulses. The output connector is interlocked, so that the PCX-7500 is disabled when the connector is removed.

Internal or External Triggering

Conveniently located front panel BNC connectors allow the PCX-7500 to be externally triggered and synchronized for specialized interconnected equipment applications. The input impedance of the trigger is selectable to either 50Ω or 10,000Ω. The synchronization output pulse is synchronized to the leading edge of the output current pulse and is active with internal or external trigger.
