LDD-1321 Configuration Software (FW ≥ v1.40)
(free of charge)

Simple configuration, control, and monitoring of the Laser Diode Driver LDD‑1321



Free software for configuring, monitoring, and logging operating parameters of the LDD-1321 laser diode driver from Meerstetter Engineering.

The software allows you to read and save measurement data and configure device settings. It also includes functions for calibration and firmware updates.

The optional Light Power Control (LPC) feature can be configured and used via the software, provided that the corresponding hardware option and the paid license are available.

Detailed Description

The LDD-1321 Configuration Software supports the operation of the laser diode driver from the initial setup through ongoing use. It is used for parameterization, monitoring, diagnostics, and remote control of the device.

Features at a Glance:

  • Monitoring of perating parameters:
    Display and visualization of relevant device parameters such as output current, voltage, and temperature
  • Internal signal generator and lookup tables:
    Configuration of current waveforms using built-in signal shapes (e.g., sine, triangle, square) as well as user-defined lookup tables
  • Parameter configuration:
    Configuration of the device’s operating and control parameters
  • Graphical analysis:
    Time-resolved display of measurement and system parameters
  • Data acquisition and export:
    Recording of operating data and export as a CSV or Excel file
  • Error analysis:
    Display of fault conditions and access to diagnostic information
  • Support of PWR-1191:
    Configuration and operation of the optional TEC control
  • Autotuning (with PWR-1191):
    Automatic optimization of PID parameters for temperature control
