Plotting Diodes with Power Supply

I understand the reasoning for having a drive circuit before a diode: to help provide a steady application of power that does not spike all over the place and maintains a smooth and proper amperage and voltage supply.

I bought a new DC power supply, and I wanted to ask the forum if this supply is capable of testing diodes directly to produce accurate output plots, in your opinion. I do have a LPM. I assumed that I chose a decent supply and there would be no issues, but I wanted to run it by those here just in case you had something to mention that maybe I should watch out for or etc.

The supply is a Instek GPS-3030DD.

Exerd;

Your new lab supply will work fine for plotting diodes with a few precautions.

I have used a similar model for some of my old testing.

Ramp the voltage up for testing, and ramp it down before turning the supply off.

For precision, you will need a good meter to monitor the voltage with a little more precision.

Let the tests begin.

Excellent. :)

I have two DPMs and will surely use one of them for better resolution during testing.

I just wanted to double-check. Thanks
