Designed for ease of use and readability, the front panel features a large 7-segment LED display with integrated dot matrix display. Instrument controls are grouped by mode and function to allow for easy setup. The display allows for easy viewing of multiple parameters such as pulse output current, pulse repetition interval set point, duty cycle set point, and pulse width set point. Discrete function buttons allow for quick configuration without a complex multiple menu system. A selection of instrument operating modes includes constant duty cycle, constant pulse repetition interval (PRI), and external trigger. During a system error, the dot matrix display provides easily readable errors to allow for quick troubleshooting. In constant duty cycle mode, the set duty cycle is maintained while adjusting pulse widths. In constant PRI mode, the set pulse interval is maintained while adjusting pulse width. In external trigger mode, the user sets the current and pulse width and the LDP-3830 will respond to an external TTL signal from a single pulse up to the maximum PRI. To maintain system uptime, the LDP-3830 provides the ability for the user to upgrade the firmware without returning the instrument to ILX. To upgrade the firmware, the user needs a computer with a USB and internet access.
