FUNCTIONS AND FEATURES

This chapter introduces you to the LDX-3232 High Compliance Current Source functions and operating features such as event triggering, analog modulation of laser injection current, and Save and Recall.

Saving and Recalling from the Front Panel

For applications where you might need to alternate between particular instrument configurations, the LDX-3232 Current Source offers a unique SAVE and RECALL feature. The SAVE feature allows you to easily store all front panel settings for any given instrument configuration. These settings, that are stored in one of ten memory bins, can be retrieved at any time with the RECALL function. This saves setup time, and it reduces the chance of setup error for tests that are periodically repeated. For example, using the configuration described in Chapter 2 where the Current Source is operating in Constant Current mode, the instrument parameters saved by using the SAVE function would be Constant Current Mode, 2000 mA range, a limit setpoint of 1750 mA, a laser current setpoint of 1500 mA, and Display Mode I. Once this setup is saved, the LDX-3232 Current Source may be configured for another unique setup. You can recall the original setup for the first experiment any time using the RECALL function.

To enter the SAVE/RECALL mode, press the SELECT switch in the PARAMETER section until the SAVE indicator LED becomes lit and the unit displays the SAVE "bin" on the display. If another bin number is desired, press and hold the SET switch and rotate the adjust knob until the desired bin number is displayed. Releasing the SET switch completes the SAVE operation and all of the instrument parameters are saved to the indicated bin number as they appear on the front panel.
