This technical note presents the results of output drift measurement tests performed on a typical LDX-3100 Board-Level Precision Current Source.

The ILX Lightwave LDX-3500B Series Precision Current Source can be modulated by an external analog signal up to 500 kHz, 150 kHz or 100 kHz depending on the model.

The measurement setup is shown in Figure 1. The LDX-3525B was placed in a temperature controlled oven and stabilized for one hour at 20oC. The LDX-3525B was placed in low (200 mA) range, …

This technical note presents the results of measurement (display) accuracy tests performed on a typical production model LDX-3525B Precision Current Source.

The measurement setup is shown in Figure 1. Each tested unit was set to drive a 1W load, with the DC output level set to 100 mA, and the limit set at 125 mA. The output was then modulated …
