Saving and Recalling from the Front Panel

For applications where several different instrument configurations may be
required for different types of testing, the LDX-36000 Series High Power Current
Sources offer a useful Save and Recall feature. The SAVE feature allows all front
panel settings for a given instrument configuration to be easily stored for future
use. These settings, which are stored in one of ten memory locations, can be
retrieved at any time with the RECALL function. This saves setup time and it
reduces the chance of setup error for tests which are periodically repeated. For
example, one test may require QCW-Pulse mode with a fixed pulsewidth of 250
µs, a pulse rate of 100 Hz, and a peak current of 3.5 A. This test is performed on
a fixture with an embedded, calibrated thermistor. A second test, using a totally
different fixture, with no temperature monitoring, may require CW mode with a
current of 5 A. Storing these two test configurations in two memory locations
allows them to be quickly retrieved and used when needed.
To enter the Save/Recall mode, repeatedly press the Parameter Select button
(Figure 3.7) until the SAVE or RECALL LED (as required) is illuminated. The
currently selected Save/Recall location will be shown in Display 1. Press the
Parameter Set button and rotate the Adjust knob to change to a different location.
Releasing the Set button completes the Save/Recall operation and all instrument
parameters will be saved or recalled as appropriate to/from the displayed location.
When a configuration is recalled from memory, the instrument is restarted and the
front panel parameters are reconfigured to the new parameter set.
